An article in Hoof Beats indicates cardiac disease is the third most significant cause of poor performance in horses, following problems with the respiratory or musculoskeletal systems.
Besides feeding humans and livestock, grains are being put to new uses.
Besides feeding humans and livestock, grains are being put to new uses.
A study conducted on a Thoroughbred breeding farm showed that initial broodmare body weight averaged 1,272 pounds (577 kilograms), with an average weight of 1,448 pounds (657 kilograms) at the end of gestation.
Equine proliferative enteropathy is an emerging disease caused by the Lawsonia intracellularis bacterium. It is seen most commonly in recently weaned foals but can affect adult horses.
Low-starch, high-fat feeds seem to help many horses suffering from polysaccharide storage myopathy (PSSM), a condition that causes painful muscle cramping known as tying-up.
Turning stallions out in pairs or groups can be moderately risk-free and allows the horses to develop social relationships.
At Colorado State University, researchers studied the effect of galloping exercise in addition to turnout for Thoroughbred foals.
Horses recovering from an acute case of laminitis must have a carefully designed feed management plan in order to avoid a recurrence of the problem.
The best way to cool a hot horse is to hose or sponge cold water over him, scrape the water off with a sweat scraper, and repeat the process until the horse is cool.
During prolonged moderate exercise, horses deplete muscle glycogen which needs to be replaced after the exercise period ends.
A note in Equine Science Update says that passive stretching exercises may or may not help your horse move more freely, and could even produce the opposite result.
When health records from 14 cloned foals produced at Texas A & M University between 2004 and 2008 were examined, it was noted that 6 of the 14 were normal at birth while 8 showed problems such as angular forelimb deformities, neonatal maladjustment syndrome ("dummy foals"), and enlarged umbilical remnants.
A study of the effect of different types of exercise on behavior among stalled horses suggested that regular exercise was likely to provide positive benefits on horse welfare, training ability, and handler welfare.
Buying hay for the winter? Here's an easy way to decide how much hay to purchase.
In a presentation at the recent Veterinary Sport Horse Symposium, Dr. Kyle Newman indicated supplementing horses with omega-3 fatty acids could have a positive effect on their health and endurance during exercise.
Quarter Horses can reach speeds of about 45 miles (72 km) per hour in short bursts. What gives cheetahs the ability to run so much faster--about 70 miles (112 km) per hour? Several factors of conformation are responsible, but part of the answer is that cheetahs use a rotary gallop, while horses and a number of other mammals prefer a transverse gallop. Many animals, including horses, use both forms in some instances.
As selective grazers, horses tend to eat some pasture plants and avoid others, leading to fields with some overgrazed and some undergrazed areas.
Reports of horses poisoned by pasture plants tend to increase in late fall and early winter, possibly because pasture grasses are less available due to dry conditions and the beginning of dormancy.
If you've competed at lots of horse shows, the drill is pretty routine. You know what will happen at the show, whom you will probably see there, and how long you'll be gone. Assuming your horse is a show veteran also, there shouldn't be many surprises.
For a horse owner, almost nothing is more frightening to think about...and most horse enthusiasts have encountered this situation from time to time, either with their own horses or someone else's. It seems that no amount of thought or precautionary management can completely protect horses from the danger, and owners from the worry, resulting from an escape.
Every foal has to go through it; every owner admits to some worries about it; and almost everyone survives it. For something that happens every year, weaning never seems to take on the status of "just another day's work." Separating a foal from its dam is guaranteed to produce some anxiety in both animals.
Colic is a fact of life for horse owners. Chances are very good that anyone who keeps several horses for several years will encounter colic at some time. Mild episodes may resolve on their own before a veterinarian can arrive, and more serious equine abdominal discomfort can often be managed with medication.
A common name for the problem is chronic obstructive pulmonary disease (COPD). It is also known as recurrent airway disease, recurrent airway obstruction, or inflammatory airway disease. The descriptions of the gelding and mare seem to discuss very different conditions because the disease can result from reactions to varying environmental stimuli.
Nationwide, improper hay storage and wasteful feeding methods cause losses of around three billion dollars a year. It is estimated that up to 10% of a farm's livestock production costs can be traced to inefficient hay management.
Glycogen is a large, highly branched sugar molecule that is stored in muscle and the liver, and is used by the body as an energy source. Made of long chains and branches of glucose, glycogen is used for quick, high-intensity exercise. Depleted muscle glycogen and buildup of its end products, lactate and pyruvate, contribute to muscle fatigue.
Few sights are worse than the tragedy of malnourished or starved horses. It is important to consider that not all underweight horses are the victims of abuse or neglect. Occasionally, horses may have or be recovering from serious conditions (cancer, inflammatory/infiltrative bowel disease, parasitism, colitis, surgery, etc.) that have led to weight loss, and their owners are doing all they can to help the horse regain its previous condition.
Serious kidney (renal) disease in horses is fairly uncommon. Clinical signs of kidney disease can be difficult to differentiate from other conditions but include lethargy, depression, inappetence, ulcers on the mouth or tongue, and edema or swelling of the legs and lower abdomen.
The power of targeted equine nutrition programs is unquestionable. Take, for instance, the feeding management practices that almost entirely relieve horses of the crippling signs associated with tying-up. By reducing starch intake and filling the caloric void with fat and fiber, many racehorses genetically predisposed to the disease have become successful athletes.
Horse owners want to provide their horses with adequate nourishment, but they may be confused about the best way to meet the protein requirements of animals with different workloads or ages.
Teff hay is a warm-season grass that thrives in a variety of climates and soil types. Despite low resistance to frost and pests, researchers have recently tested teff to see how the grass stacks up against cool-season standbys, timothy and orchardgrass.
California researchers performed a retrospective study on the prevalence of cecal intussusceptions. An intussusception occurs when a segment of intestine pushes into another section of the organ, similar to the way in which a camera lens slides in and out of its casing, and remains fixed.
Most horses affected with equine metabolic syndrome (EMS) are overweight and have abnormal fat deposits that include a cresty neck, fat around the tailhead that makes the tail look inset into the body, and fat pads around the shoulder, sheath, or udder.
Small intestinal colic can result from gas or fluid distension, obstruction of the small intestine (ileal impaction or roundworms), or twisting of the gut (small intestinal volvulus or pedunculated lipoma in old horses).
Colic of the large intestine can result from gas or fluid distension, obstruction (impaction or enteroliths), or twisting of the gut (as in large intestinal volvulus or displacement of the large colon).
Endoscopic examination of the stomach, sometimes referred to as gastroscopy, removed all guesswork from gastric ulcer diagnosis.
Obstruction of the esophagus, commonly known as choke, is a life-threatening condition for horses and a panic-inducing event for their caretakers.
Vaccination with gonadotropin-releasing hormone (GnRH), a reproductive hormone, might decrease unwanted behavior in stallions and mares, researchers recently reported.
Intrauterine placement of marbles in pony mares did not change reproductive physiology or normal sexual or social behavior, according to a study conducted by researchers from the University of Liverpool.
In cases where a thorough veterinary exam does not turn up a medical explanation for the horse's actions, changes in feed management may be important in modifying the way a horse behaves. Advice from a professional horse trainer or riding coach is also an option, especially if the horse presents a danger, rather than just an aggravation, to it owner or handler.
The main role of the equine skeleton is to provide structural support. In addition to bones, the skeletal system also includes tendons, ligaments, and cartilage. Each element of the musculoskeletal system must be functioning correctly in order for the horse to travel soundly.
Researching the effects of yeast culture supplementation in animals began with ruminant nutritionists. As these scientists uncovered the positive effects of yeast culture supplementation in cattle and other ruminants, equine nutritionists began to measure the effects of supplementation in horses.
Each type of omega-3 has distinct functional properties. Seafood/algal omega-3s, also known as long-chain omega-3s, are more potent than terrestrial plant sources of omega-3s and boast certain functions that terrestrial plant based omega-3s simply cannot perform.
Suppose that unexpected events- floods, fire, winter storms-play havoc with horse management. As horse owners put together a disaster plan and cope with difficult situations, one of the first concerns should be minimizing changes in feed management.
At the 2008 convention of the American Association of Equine Practitioners, horse owners were allowed to attend a seminar on the subject of equine nutrition. The workshop identified nine keys to understanding horse nutrition. Keeping these points in mind should help horse owner's work out the best feed management plan for their horses.
The inherent athletic ability of the horse is impressive. However, to achieve optimal performance in any equine sport, a conditioning program must be designed that improves cardiovascular function, capillary density in muscle, flexibility, bone strength, increased muscle mass, increased energy substrate storage, and more efficient utilization.
The most important nutrient in the horse's diet is one that is rarely added to feeds: water. The amount of water required by the horse is determined by the magnitude of water losses from its body. These losses occur through feces, urine, respiratory gases, and sweat and, in the case of lactating mares, milk.
Should I add more fat and fiber to their diets this winter?
Feeds are more than a composite of cereal grains, soybean meal, and a dash of vitamins and minerals.
EMS is one of several disorders affecting horses that is either triggered or aggravated by excessive starch and sugar intake.
The sport in which horses participate often dictates the body condition in which they are maintained. Polo ponies are typically sleek and trim their fitness evident in a tight, tucked-up appearance. The same can be said of most racehorses. Pleasure horses, those mounts used to poke around trails and forests, are sometimes softer and less muscular, carrying more body fat.
A number of treatment options have been used to evacuate sand from horses' gastrointestinal tracts. Previous research projects studying the effects of feeding psyllium to remove intestinal sand have had mixed results.
Gastric ulcers are very common in performance horses, affecting more than 90% of racehorses and 60% of show horses. There is growing evidence that the type of hay fed to horses has a significant impact on acid neutralization and the incidence of gastric ulcers.
If you've paid careful attention to your receipts from the feed store, you certainly have noticed that the price of horse feed has crept up to unheard-of levels. And while it might be tempting to assign blame to your local feed manufacturer, larger forces are at work.
Everybody knows horses need forage and grain...but how much? How often? What kind? What else? The answers may be slightly different for each horse depending on size, breed, use, and stage of development.
Proper nutrition of the mare throughout pregnancy and lactation and of the young horse during its first two years of life will help prevent developmental orthopedic problems
Equine nutritionists and researchers are uncovering interesting trends related to body condition and metabolic conditions, some of which directly relate to whether certain sport horses are as susceptible to metabolic conditions as horses that are exercised from time to time or not at all.
If the horse is fed in a group where he must eat quickly to avoid competition, isolating him at feeding time may help. Making sure the horse is not quite so hungry at mealtime, either by feeding some hay before grain or by feeding smaller meals more frequently, may slow the greedy eater.
It's worthwhile to cater to the horse's nature by making turnout part of his daily schedule.
While bone tissue continues to respond to exercise throughout the horse's life, cartilage loses almost all of its ability to adapt or regenerate by the time the horse is mature.
Excessively high insulin sensitivity and a build-up of glycogen in the muscle fibers are also characteristic of polysaccharide storage myopathy (PSSM), a chronic form of tying-up syndrome. Horses with clinical signs of PSSM have been known to benefit from diets lower in starch and higher in fat than traditional equine rations.
Even the cleanest, best-quality hay is likely to contain a moderate amount of fine material. Collectively known as the respirable dust concentration, or RDC, these fine particles can cause severe airway irritation in sensitive horses.
Horses need to consume both omega-3 and omega-6 fatty acids, but the traditional equine diet tends to provide a skewed ratio of these compounds, minimizing the supply of omega-3s and oversupplying omega- 6s. Continuing research is revealing more information about the benefits of supplementing horses with omega-3 fatty acid to achieve a more nutritionally sound balance.
A pastured horse develops hair loss, itching, dermatitis, colic, laminitis, or even sudden death, and the owner is certain the problem must have been caused by something the horse touched or ate. The first and most urgent task is to have a veterinarian diagnose and treat the affected horse. The second, and possibly more difficult, problem is to prevent another poisoning occurrence, a challenge that involves identifying susceptible horses as well as finding and removing the poisoning agent.
Flehmen is the term used to describe the behavior in which a horse extends its neck, raises its head, and inhales as it rolls its upper lip back, displaying its front teeth.
The relationships between growth, nutrition, bone strength and development, body weight, and the forces applied to bone are all orchestrated in a careful balance when optimal growth is achieved.
Every horseman has seen, at one time or another, the telltale signs of a thin horse.
A horse's weight-carrying ability depends on a number of factors.
Knowing what to feed, and in what amount, is often the key to overcoming metabolic disorders.
The racing success of a Thoroughbred horse is determined by a multitude of factors, many of which are impossible to evaluate. Thoroughbreds destined for the racetrack are often sold at weanling or yearling sales where buyers must rely on subjective methods, rather than performance history, to select future athletes.
One of the most important goals for Thoroughbred breeders is to produce a fully-grown, sound, and top-performing athlete. Rapid growth in horses has been associated with compromised skeletal growth; however, horses that grow too slowly may not reach optimal size, possibly reducing their sales value and lessening their chances of becoming elite athletes.
There is a belief among many people that defects in conformation predispose racehorses to poor performance and injury, and horses with obvious conformation problems tend to bring lower prices at public auction.
The care and management of old horses has been the focus of much scrutiny of late. The reason is obvious: horses are living much longer than they once did, and horsemen needed to know how to offer appropriate care.
Therefore, a basic understanding of the function fermentation plays in a wide range of species is critical when considering its importance in the horse. An appreciation of the continuity of microbial fermentation across several species allows information gathered in one species to be used for the benefit of other species.
Certain situations trigger the pH of the hindgut to drop sharply. The two most common causes are the overconsumption of high-starch concentrates or pasture grasses rich in fructan. The demands placed on horses-as athletes and as breeding animals-dictate that substantial quantities of energy-laden feeds be consumed.
Colic is a catch all term used to describe abdominal discomfort from any cause. Signs of horse colic include pawing, kicking at the belly, looking at or nipping the flanks, rolling, sweating, or straining as if to pass urine or feces.
Hay, or some other source of fiber, is absolutely necessary to the health and function of the horse's digestive tract. Because of a scarcity of hay in many regions, can you just skip feeding hay this winter and make up the deficit by doubling your horse's grain ration?
Scientists have revealed that Dr. Green may not be the best prescription for all horses. Under specific growing conditions, common pasture plants can harbor sufficient sugar to cause metabolic problems in certain horses that are especially sensitive to carbohydrates.
When a pile of lawn clippings is placed in front of him, the horse can consume the cut grass much more quickly than if he were grazing naturally. If your horse has a tendency to bolt his feed (eat it very quickly), he may do the same with lawn clippings.
All horses are subject to digestive upsets associated with lush spring pasture. The content of highly fermentable carbohydrates in lush pasture can be overwhelming to the unadapted digestive system.
The bacteria produce toxins that irritate the intestinal lining of the animal they infect. Some strains cause illness in horses, and others are responsible for infections in cattle and other animals.
An aged broodmare sometimes requires an extra dash of diligence by caretakers and health-care professionals. Despite some misguided lore, it is possible for those grizzled, sunken backed doyennes of the broodmare band to be fleshy and in fine fettle during all phases of production.
European warmbloods and warmblood crosses have become prominent as sport horses in the United States, where they compete regularly in dressage, show jumping, and three-day eventing. Feeding nutritionally balanced rations and attending to nutrition-related idiosyncrasies of warmbloods are the first steps in producing and maintaining sound athletes.
Insulin resistance occurs when the cells become less sensitive to insulin, thereby limiting the uptake of glucose. When this occurs, more and more insulin is required to move glucose out of the bloodstream and into cells. When insulin resistance is severe enough, glucose accumulates in the blood, thus limiting the availability of energy to cells.
Digestibility of various grains was quantified and fecal analyses were conducted to establish which grains held the greatest risk of hindgut starch fermentation and acidosis. Hindgut acidosis can impair performance, and could be career-threatening if it leads to laminitis.
In a recent study conducted by the Virginia-Maryland Regional College of Veterinary Medicine (VMRCVM) and the College of Agriculture & Life Sciences at Virginia Tech, 300 horses were examined between June and August of 2006. Of these, more than half (51%) were determined to be overweight or obese.
Horses have evolved over millions of years as grazers, with specialized digestive tracts adapted to digest and utilize diets containing high levels of plant fiber.
The care and management of old horses has been the focus of much scrutiny of late.
The most popular types of forage cubes are made from coarsely chopped alfalfa hay, timothy hay, alfalfa/grass hay, whole corn plants, and alfalfa hay/whole corn plants," said Crandell. Horsemen derive numerous benefits by choosing hay cubes over more traditional long-stem hay.
Both protein amount and type are important in the diets of growing horses because certain amino acids cannot be produced in the horse's body and must be provided by ingested food. The site of protein digestion is important to optimal absorption.
To understand splints, we need to remember that prehistoric ancestors of the modern horse had multiple toes on each foot. The horse of today walks on the tip of its middle toe, but vestigial traces of the other toes are still present. Two of these leftover toe bones, called splint bones, lie along the inner and outer sides of each cannon bone beginning just below the horse's knee or hock and tapering to an end above the fetlock.
Scientists are delving deeper into how certain fats help horses. Researchers have focused their attention on two distinct families of fatty acids: the omega-3 family and the omega-6 family.
Forages, concentrates, and other basics of equine nutrition.
Yields of timothy hay grown in some areas of New York, New Jersey, Maryland, and Pennsylvania have dropped as much as 70%. Shortages of this popular horse hay have led growers to look at other forage crops that produce high yields, offer equivalent nutrition, and are less susceptible to cereal rust mite damage.
Following Hurricane Katrina it became clear that thousands of cattle, horses, and other livestock were in need of basic food and care. Tons of hay and pallets of feed were required immediately, and in enormous quantities. It was clear that no quick or easy "fix" was going to sustain these large animals throughout the months ahead.
Foals are generally weaned when they are somewhere between four and six months of age. Well before this time, young horses need to be eating grain regularly, deriving the majority of their nutrition from pasture and concentrates. One way to do this is by providing an enclosed feeding area in the pasture that allows foals to enter while excluding mares.
Yearlings that commanded bids higher than the median price of the session in which they were sold tended to be heavier and slightly taller, but not fatter, than yearlings receiving bids below their session's median price.
While very young, very old, or ailing horses may need specific changes in stable routine, healthy horses with an intact coat can usually tolerate winter weather with few problems if owners pay attention to basic feeding and management principles.
Most mare owners know the dangers of grazing late-pregnant mares on endophyte-infected tall fescue. The grass causes legions of problems, collectively called fescue toxicosis, in broodmares: prolonged gestation (as long as 13 to 14 months), foaling difficulties, thickened placentas (including "red bag" emergencies), and a decrease or complete absence of milk upon delivery.
At times, identifying a food allergy seems more like trial and error than hard-core science. While diagnosis involves tremendous dedication, the result--a happy, healthy horse--is well worth the effort.
As we all know, hay is often a mainstay of winter diets.
Lives of Thoroughbreds in race training differ greatly from those of most sporthorses.
It is most commonly seen as a sign of dehydration and electrolyte depletion among horses performing in endurance races.
Can't live with them, can't live without them. Humans have been inundated with the supposed evils of carbohydrates. But what contributions-good or bad-do carbohydrates make to the equine diet? Must horsemen be mindful of counting carbs in their horses' diets? As with most topics in equine nutrition, the question cannot be answered with a simple yes or no.
Weaning is synonymous with stress. The process produces anxiety among foals and mares, not to mention their caretakers. To ease the transition all foals must face-from maternal coddling to self-sufficiency among peers-owners can do a little homework before the day of parting arrives.
Extruded, pelleted, or sweet feeds can all provide energy, and each feed form has other attributes that owners should consider as they look for the best products to suit their animals. Examining the pros and cons of each type of feed can clarify the decision.
The plant disease might involve individual kernels or clusters of kernels on an ear of corn. Discoloration of kernels is usually the first visible sign, with kernel caps becoming salmon-pink or a light shade of red. Once the signs develop, the pathogen may continue to spread on the ear, knitting a cotton-like growth that might eventually cover the entire ear. Complete coverage is likely to occur if moisture was trapped beneath the husk. Not all infected kernels, however, show signs.
A sound nutritional plan, along with careful attention from a handler, veterinarian, and farrier, can save many starved horses. Recovery may take several months, and during this time each horse must be evaluated and treated on an individual basis.
Grand Prix show jumper turns to careful equine management in his quest to qualify for the Olympics.
This result indicates that laminitis flare-ups may be triggered by allergens and also by reactions to ingredients in common vaccines.
If a horse sweats little, access to a generous amount of high-quality hay and a salt block will provide sufficient electrolytes. If the horse sweats profusely or is allowed only minimal forage, an electrolyte product containing sodium, chloride, and potassium is recommended. Consistent supplementation with electrolytes may be just the thing to transform lackluster summertime performances into winning ones.
The most important component of any feeding program is forage, be it pasture or hay. Without question, a survey of the paddocks, pastures, and other turnout areas in which your horse may reside is in order before finalizing a boarding arrangement.
As the grass brightens from brown to green, the nutrient content of the plant changes considerably. Horses will undoubtedly relish the newfound forage, but care must be taken to allow only the amount of grazing time necessary to sustain optimal body weight. If horses are allowed unchecked access to spring grass, they can quickly become overweight. The perils of obesity include decreased stamina and a greater likelihood for unsoundness.
What makes a police horse's job unique is the variety of experiences and challenges that each day brings. While all horses are expected to respond to their riders' signals, it's of paramount importance that the mounted police officer can trust his horse to remain calm and obedient, no matter what happens.
Soybean hulls are high in pectin and other soluble fibers. Because they are digested mostly in the cecum and contain relatively small amounts of starch, their use in equine diets does not pose a high risk for colic and laminitis.
As forage for horses, alfalfa is both revered and disparaged. While it may not be the best hay choice for all horses in all management setups, high-quality alfalfa possesses sufficient nutrients to support high production such as growth and lactation.
A number of feedstuffs can be incorporated into horse feeds to satisfy protein requirements. Though soybean meal is used preponderantly in the horse feed industry, other sources can deliver adequate protein, especially to mature horses.
Recurrent exertional rhabdomyolysis, also called tying-up syndrome, refers to the severe muscle cramping and cellular damage seen in some exercising horses. Various forms of tying-up affect horses of several breeds and are caused by different metabolic processes.
These terms are common names for conditions that restrict airflow in the laryngeal area. In both cases, noisy breathing and exercise intolerance are probably the first signs that will alert an owner or trainer to the problem.
Equine grass sickness (EGS) is a mysterious and often-fatal disease that strikes down healthy young horses as they graze. Most cases have occurred in England, Wales, and Scotland, but EGS has also been seen in Europeand South America. Mal seco, an equine disease reported in South Africa, appears to be identical.
Dorsal displacement of the soft palate (DDSP) is a misalignment of tissues in the horse's throat. This condition, which is common in horses that work at high speeds, causes a drop in performance because affected horses are unable to breathe freely.
Mares come into estrus about seven to 14 days after giving birth. This period coincides with the occurrence of diarrhea in about 80% of foals, hence the name "foal heat diarrhea." There is no certain explanation as to why foals get diarrhea at this time, and various possible causes-influence of hormonal changes in mare's milk, foal begins to eat mare's manure, bacterial infection, parasite infestation-have been advanced.
Exercising horses need a certain level of dietary protein to build and repair muscle tissue and to replace the protein lost in sweat. This study was designed to test whether decreasing dietary protein quantity, while increasing protein quality by supplementation with lysine and threonine, could reduce the negative effects of excess protein while providing sufficient amino acids to support tissue maintenance.
Why do horses behave the way they do?
Lactating mares use energy, calcium, and phosphorus at a greatly increased rate.
Most oats fed to horses are whole, meaning each kernel is encased in a hull or fibrous sheath. Oats are frequently subjected to processing, typically rolling or crimping, which cracks the hulls and adds slightly to their digestibility.
In addition to the type and amount of concentrate being fed, owners of hyperactive horses should look at other areas of management. Horses that are kept in a stall or small corral much of the day will likely be more difficult to handle than horses that have more liberal access to free exercise. Full-time turnout and regular work are sometimes all that is necessary to curtail the expression of excess energy.
Horses, like humans, come in a variety of body shapes. Some breeds and individuals tend to be "easy keepers," naturally assuming a well-rounded shape. Others always seem to look a bit thin and ribby, no matter how they are managed.
Studies in ruminants and ponies found that high levels of aluminum disrupted the use of calcium and phosphorus. On the other hand, one study found no adverse effects on macro- or micromineral digestibility and balance when small amounts of aluminum (less than 1500 parts per million) were ingested.
Higgins, on the other hand, weighed a walloping 243 pounds at 28 days of age. Colts of his age born in April usually hit the 205-pound mark. This fact makes Higgins about 18% heavier than others his age. Higgins is not obese, in fact few foals are, but he possesses height and scope, likely a reflection of his tall, lanky mother.
When the realization hit that his dam was nowhere to be found, Shout became uneasy and lapped the field at a full tilt gallop. Higgins did little to ease Shout's anxiety, merely watching the seemingly half-crazed Shout careen around the field. Skean seemed less fazed by the separation; she may have even been relieved to bid farewell to her youngster.
Skean, completely exhausted, lay motionless on the floor, breathing deeply. Milk once again flowed from her udder. Meanwhile, the veterinarians resuscitated the foal and gave him a thorough once-over, declaring him healthy except for a few fractured ribs. Skean gently rolled onto her chest, folded her legs underneath her, and offered the softest, most endearing nicker any mare could possibly bestow.
Thousands of horses change hands annually at public auctions. While the most conscientious of buyers may flood the seller with innumerable questions regarding their most recent equine acquisition, many horses are shipped without feeding instructions. When they arrive at their destination, the horses are often placed immediately on the new owner's feeding schedule, which may be considerably different than the familiar one.
Almost all the guidelines on feeding and caring for horses are aimed at the middleweight or light horse population, those that weigh in at about 1,000 pounds or so and little information is available regarding the equine extremes - ponies and draft horses. Generally speaking, horses are horses regardless of their size, but there are some differences in the nutritional requirements and management of these equids.
Raising an orphan foal is a formidable task. Often nurse mares are difficult or impossible to acquire during emergency situations, and bottle-feeding an orphan foal requires a significant commitment of time and resources.
Researchers at the University of Kentucky measured the voluntary intake of big bluestem, Indiangrass, eastern gamagrass, and timothy grass hays in a group of mature horses.
Bran mashes remain a staple in the feeding regime of some horsemen and continue to be a traditional meal for horses recovering from sickness, for mares immediately following foaling, and for aged horses with dental problems. A bran mash is often the meal of choice for horses following an intense workout, especially for those that do not drink adequately during or after intense exercise and teeter on the brink of dehydration.
In order to achieve maximal improvement in hoof health, a horse should consume 20 mg of biotin per day. If improvement has been seen within eight to 15 months, the horse will need to remain on biotin the rest of its useful life to maintain that improvement. Cutting the dose is not advisable because it may affect the results, and care should be taken not to buy more than what can be used up in six months.
Wood chewing is simply the nibbling and splintering of wooden surfaces with the teeth; sometimes the wood is swallowed and sometimes not. This behavior is thought to spring from the horse's natural appetite for a varied diet.
The most popular way to feed salt ad libitum is a salt block. These were originally designed for cattle, which possess a rough tongue, but are suitable for most horses. Occasionally a horse may be seen biting or gnawing at the corners of the block.
Random blending of whole grains or protein supplements with commercially manufactured feeds can skew the nutritional balance of feeds and induce growth problems in young horses. The best way to ensure sound nutrition and thus favorable growth, performance, and production is to choose a fortified feed that best complements the nutritional profile of the intended forage and the proposed use of the horse.
During normal bone growth, cartilage is remodeled into bone. It is during this physiologic revision that ossification goes awry and OCD lesions originate.
Evaluating the body condition of pregnant mares may become more difficult during late gestation, as the combined weight of the fetus and amniotic fluid may pull the skin tightly over the vertebral column and ribcage. Therefore, it's best to place emphasis on other key areas: along the withers, behind the shoulder, and around the tailhead.
The components of a typical diet for horses in Australia and New Zealand may seem an unlikely lot. Lupins, tick beans, and copra meal are certainly not common in the vernacular of the horse community in North America. Nutritionists have adapted these native, though seemingly unusual, ingredients into well-balanced rations that support growth, performance, and reproduction.
While obesity-associated laminitis is not well understood among researchers and veterinarians, affected horses may go on to lead otherwise healthy lives if treatment is swift and diligent. Recommended treatments center around corrective trimming and shoeing, use of nonsteroidal anti-inflammatory medications for pain, and strict diet. Forced exercise can be imposed once all laminitis-related pain has abated.
Equine colic is loosely defined as abdominal pain. The causes are numerous, and the signs of discomfort (rolling, kicking at the abdomen, pawing, sweating) are familiar to most experienced horse handlers. Colic is one of the most common health emergencies, with an incidence of just over 9 cases per 100 horses in an average year. It is a leading reason for surgery and a frequent cause of death in horses.
Now you're planning to give your horse a well-earned rest. You know he'll enjoy a few months out of his stall, rolling in the grass and taking afternoon naps with his pasture buddies. You realize that you'll be modifying just about everything in your horse's day-to-day routine. How can you keep your horse healthy as he makes this change?
First and foremost, hair helps in the formidable task of bodywide temperature regulation, and one integral aspect of this role is providing a shield against environmental conditions, hence the dense, wooly coats of winter and the slick, short coats of summer. Other functions of hair include protection against predatory insects and a pathway for transport of pheromones and other physiological signals from the body.
Figures released by the USDA and the United Nations show that North African and Middle Eastern countries have steadily increased imports of animal feeds in the last decade.
The importance of calcium in the diet of horses and ponies is crucial. When coupled with phosphorus, the two minerals compose up to 70% of the total mineral content in the body. Calcium is necessary for skeletal, cardiac, and smooth muscle function, nerve conduction, and a host of other metabolic reactions.
For mares with known or suspected fescue exposure, managers should be sure the foaling is attended and a veterinarian is available. This is recommended even if mares have been treated with domperidone or fluphenazine. The attendant may need to cut the thickened placenta or help the mare expel a very large foal that is several weeks overdue.
Products defined as digestive aids can be broadly categorized as either probiotics or prebiotics. These aids can be fed as part of the horse's regular diet, or administered only occasionally in response to a particular need.
Do not choose supplements on price alone, but look for economical products that meet actual needs. A concentrated, low inclusion product will be more expensive than one in which the dose is larger. Look at the weight of the pack and the dosage amount, not the size of the bucket.
Keeping an endurance horse fit and healthy involves more than just putting in a large number of miles on trails. The work required of these horses is quite different than that of any other equine athlete. The challenge is to provide the correct combination of nutrients that will support the special needs of these athletes during both training and competition.
In the wake of the 2001 outbreak of equine foal and embryo deaths known as mare reproductive loss syndrome (MRLS), proper pasture development and maintenance have received increased attention. The need to determine a cause for the devastation visited upon Kentucky and adjoining states by MRLS led many researchers to look towards pasture anomalies for clues.
Plain oats may have a place in the diets of some horses. Mature horses in light work and without the demands of reproduction may do just fine on plain oats, especially if pasture is scarce or low quality or if the forage source is low in energy. If oats are chosen as a way to increase caloric intake, a feed balancer should be used to ensure proper levels of vitamins and minerals are consumed.
Manufacturers of horse feeds use molasses to improve palatability, reduce dustiness, eliminate or decrease sorting of certain components in a textured feed, aid in the pelleting process, improve mixing integrity of a concentrate, and add nutrients or other ingredients to a ration.
Temperament is certainly a factor in deciding which stallions make good candidates for shuttling, but it is only one small piece of the decision-making process. Bloodlines are a larger factor.
Horses recovering from colic, surgery, high fever, or colitis can present many challenges for their owners, but one that is frequently overlooked is how to feed horses through the illnesses. While countless researchers have devoted years of study to determine the proper nutritional balance for horses of different ages and workloads, little has been done to outline proper nutrition for the sick adult horse.
Acute arthritis can be caused by injury or by bacterial or viral infection. Chronic arthritis is often osteoarthritis that results from the cumulative effects of day-to-day activity and stress. Old injuries, joint infections, and years of training and performance can all lead to the development of joint pain and stiffness. Poor conformation, hoof deformities, and problems with trimming or shoeing are other contributing factors. Probably there is some genetic influence also.
The polished weanlings and yearlings and the athletic two-year-olds that grace the sales rings throughout the world today are slightly different from the horses that went before them. Technology and research have combined to provide consignors and buyers with a slightly different opinion of what constitutes good health.
Some veterinarians provide dental treatment in addition to their other services. Others prefer to supervise a professional equine dentist who has the specialized training, equipment, and experience to complete the work quickly and competently.
Have an equine dentist do a thorough oral exam to make sure the teeth do not have sharp points or edges that are irritated by the pressure or position of the bit. In young horses, the shallow-rooted wolf teeth sometimes interfere with the bit and can easily be removed by a dentist or veterinarian.
How can a rider decide what size equine is right? To answer this question, it is necessary to consider several factors about both the rider and the horse.
Feeding well-balanced rations and attending to nutrition-related idiosyncrasies of warmbloods are the first steps in producing and maintaining sound athletes. The primary nutritional goal of managing young warmbloods should be ensuring slow, steady growth and reducing the risk of developmental orthopedic disease.
In an effort to determine the effect of yeast on digestion in horses, researchers in France carried out a study to look at the influence of feeding a preparation of Saccharomyces cerevisiae, a strain of yeast, on microbial profiles and fermentation patterns in the large intestine of horses fed a high fiber or a high starch diet.
Proper nutrition is extremely important in managing horses with metabolic disorders. Regulating the amount and type of feed, with special attention to carbohydrates, allows many horses to show minimal disease signs, maintain healthy body condition, stay comfortable, and safely perform exercise.
Stocking rate is defined as the number of horses allowed to graze a unit of land for a specific amount of time. Making the most of pastures by optimizing stocking rate may reduce other forage expenditures. Stocking rate is contingent upon numerous factors including grazing behavior, level of pasture management, forage species, seasons, and weather patterns.
Unlike some fungus or mold species that cause problems in stored grain, Fusarium grows on corn plants before they are harvested. Stress from weather or insect damage can make plants more susceptible.
Regardless of their size, all equines have the same basic nutritional needs. Each animal must consume enough water, forage, and (possibly) grain to meet the requirements of growth, tissue repair, reproduction, exercise, and maintenance of all body systems. Factors such as body size, age, breed, work, climate, health status, and metabolism affect the type and amount of hay, pasture, and grain a particular horse should be given.
Pica is the desire to eat unusual substances that possess little or no nutritional value, such as dirt, wood, hair, and feces. This phenomenon has been observed in horses of all ages, breeds, and sexes.
Enteritis is an inflammation of the small intestine. More specifically, anterior (or proximal) enteritis affects the duodenum and jejunum, sections of the small intestine anatomically closest to the stomach.
Depending upon the severity of the disease, horses may have to receive nutrition parenterally (intravenously) during treatment. This is particularly true if a bout of anterior enteritis lasts longer than three or four days.
Continuous ingestion of feedstuffs keeps the digestive tract running smoothly. Modern management practices dictate that many horses remain in confinement for long periods of time with limited or no access to pasture.
Forage remains the primary constituent of most well-balanced equine diets, but nowadays it can be proffered in a multitude of forms, from traditional long-stemmed hay to symmetrical cubes. The five most common forage forms are pasture, hay, cubes, pellets, and haylage.
Optimal nutrition of the performance horse hinges foremost on the exercise it performs. Just as the diet of a human bodybuilder is dissimilar to that of a marathon runner, horses are fed with performance goals in mind.
Weaning is a stressful time for foals and mares. While mares are often ready to say good-bye to their rambunctious, rowdy charges, foals can be far more fretful. As such, weaning rarely negatively impacts a mare. In fact, some mares may blossom and begin to flesh out once they are freed from the burden of milk production.
Forage is chock full of fiber, a dietary component that is subjected to microbial fermentation in the cecum and colon of the horse. This fermentative process produces volatile fatty acids, important sources of energy for horses fed high-forage diets. Fiber can supply a horse with 30-70% of its digestible energy requirements.
Feeding horses properly is not difficult. Reliance upon an educated horseman, a veterinarian, or an equine nutritionist is paramount if a feeding management question arises. This is particularly true when confronted with an old wives' tale.
While some old-fashioned feeding practices remain pertinent in this day and age, others have fallen by the wayside. Over the last several decades, research has debunked some commonly held beliefs concerning the nutritional management of horses.
Understanding the methods used to process feeds and knowing why they are used will make the idea of feeding processed feedstuffs more savory.
The ideal environment for a mare that is about to foal is a clean grass paddock where the mare can be observed with as little disruption as possible, but inclement weather or insufficient lighting can make this impractical.
Few topics in equine nutrition stir more controversy than feeding the weanling. Many factors add to the confusion of providing nutrition at this critical stage of growth.
Some horses are metabolically inclined to be hard keepers while others have medical, psychological or environmental reasons for having difficulty in maintaining weight.
Insufficient caloric intake is the primary cause of failure to maintain sufficient body condition in horses. A variety of reasons may account for caloric deficiency. Some are easy to pinpoint and simple to address, such as parasite loads or teeth problems. Others are impossible to diagnose without euthanizing the horse and performing a necropsy. Physical problems of the digestive tract account for many of these problems, but there may be psychological and environmental reasons as well.
As we become more aware of the problems facing geriatric horses, they have a much better chance at surviving into their golden years than they would have had 100 years ago. Strong emotional ties can motivate many owners to be observant of their beloved beasts and to take the extra steps it requires to maintain them in health and comfort.
There are many additional "tricks of the trade" that can be applied to help the halter horse reach his optimum potential, but the successful basics remain the same. It is essential for halter horses to be on a properly balanced diet. Exercise must be carefully designed for each individual animal to avoid potential injury and build the valuable muscle tone that can make a difference between winning and being just another horse in the class.
Every equine practitioner appreciates the delicate nature of the equine gut. Problems related to the small intestine and large intestine are well understood and routinely treated. What may be surprising to many is how often the stomach is affected. Specifically, the incidence of gastric ulcers is extremely high, particularly in performance horses.
To anyone who has ever loved a horse, every healthy foal is a miracle. It is a joy and a wonder to watch them stand on their wobbly legs, take their first tentative steps, and find their first meal. While the vast majority of foals born every year find their way into the world in the usual fashion, occasionally a foal will arrive that provides a new definition for the word miracle.
Vitamin E is a non-toxic, fat soluble vitamin which has an important role in many physiological functions such as reproduction, immune response and nerve and muscle function. It also has overlapping yet independent roles with selenium, an essential trace mineral.
Sorting through the numerous supplements displayed on the shelves of your local feed store or in the pages of your favorite horse magazine can be difficult. As an equine nutritionist, it is sometimes difficult for me to figure out the intended purpose of certain supplements. However, supplements can be divided into two broad categories.
Subclinical signs of selenium deficiency may be easily overlooked. Because the major role of selenium is in the oxidative defense system, deficiency would first compromise cellular integrity.
Rice bran is a highly digestible by-product of the rice milling industry. It should be heat and pressure stabilized prior to feeding to prevent rancidity and digestive upset. The primary feature of stabilized rice bran is its high (20%) fat content.
When a young horse begins training, horse owners and managers must realize the horse is still growing. The dual demands of training and growth make it especially important to pay attention to proper nutrition.
This diet food scenario has proven very effective when feeding broodmares in late pregnancy. Most mares will sail through pregnancy in good body condition and can be fed the recommended amounts of sweet feed to provide essential protein, vitamins and minerals.
Flat-footed horses are very sensitive to the type of footing on which they live and exercise. They are intolerant of exercise on rough ground and may require pads to help them to be comfortable. Careful attention to providing corrective trimming and shoeing can greatly help horses that have hoof abnormalities.
Methods to maximize the benefits of alfalfa in equine diets and balance the weaknesses often associated with alfalfa.
Signs of equine dental problems are as varied as are the horses that present them. From the obvious, handfuls of feed dropping from the mouth as the horse eats and grain passing directly through the animal, to the subtler head tilting and weight loss, the solutions involve knowledge, proper equipment, and fortitude.
Do we have adequate research and understanding of what the impact of high-fat diets might be to their metabolism or to their overall physical development?
