Contagious equine metritis and equine viral arteritis are sexually transmitted diseases (STDs) that affect horses, causing problems such as low conception rates, abortion, and sick or weak newborn foals.
Researchers from the University of Kentucky, University of California, and Colorado State University investigated the efficacy of an equine recombinant follicle stimulating hormone (reFSH) in noncycling mares housed under natural light conditions.
Horses have a gestation period that lasts approximately 340 days. If that sounds like a long time to wait for the baby to be born, you’d be no better off raising llamas (350 days) or donkeys (365 days).
Researchers in Denmark developed a product that would help mares with infertility caused by dormant bacterial infections of the uterus.
Potentially pathogenic bacteria were isolated from 31% of over 8,000 cultures taken from mares of different breeds in central Florida.
The majority of mares give birth without difficulty, moving smoothly through the various stages of labor and parturition. However, mare owners and foaling managers need to know when the mare is not making progress and may require intervention to ensure the well-being of mare and foal.
Stallion fertility can be influenced by nutrition, management, presentation of mares, and the stallion’s age, among other factors. To ensure the best pregnancy rates, managers need to take several factors into consideration.
Deciding whether to breed on foal heat depends on many factors, including the health of the mare after parturition and the breeder's goals for the resulting foals and the mare.
Breeding mares by artificial insemination can be accomplished using fresh semen, chilled semen, or frozen-thawed semen. Each option has its own method of use and average rate of pregnancy. Of these three techniques, using frozen-thawed semen to inseminate mares seems to be most tricky.
Premature foals born before 300 days of gestation have a low chance of survival. However, many premature foals do well with supportive care, eventually growing as well as full-term foals and catching up by or before two years of age.
