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.
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?
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.

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.
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.

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.
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.
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.
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.
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.
<p> Is it safe to feed sunflower seeds to horses?</p>
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.
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.
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.
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.

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.

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.
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.

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.
