Manipulating the estrous cycle in mares is a big part of many breeding operations, and medications play various roles in the process. There are several options for inducing ovulation, including human chorionic gonadotropin (hCG),
Researchers have recently identified a new equine respiratory ailment that presents clinical signs similar to heaves, but that is progressive and has a poor prognosis for affected horses. The researchers have postulated that the disease, dubbed
Success when breeding older maiden mares depends on the management of several factors
Veterinary internists met June 6-9 in Seattle, Wash., for the 25th Forum of the American College of Veterinary Internal Medicine (ACVIM) to discuss the latest research on the internal workings of horses and other animals.

In a survey of horses arriving at several different show and sale facilities, researchers found that as many as 4% of the population were shedding equine herpesvirus-1 (EHV-1) from nasal passages, and as many as 2% were shedding equine
The National Human Genome Research Institute announced the first assembly of the completed horse DNA sequence on Feb. 7, 2007. Why would a human health
A study of one Lexington, Ky., Thoroughbred farm showed that on average, 30% of the farm’s foals developed Rhodococcus equi pneumonia during the 2004 and 2005 foaling seasons. Researchers searching for a source of the disease questioned i
One of the biggest challenges in successful equine reproduction is uterine inflammation. Increased inflammation can destroy spermatozoa before they have a chance to fertilize the egg, and it can create a hostile environment that kills an embryo.
Glycogen-branching enzyme deficiency, a genetic mutation affecting a particular glycogen-storage enzyme, is traced back to Quarter Horse sire King or his sire, Zantanon. Up to 8% of Quarter Horses and Paint horses carry the GBED defect.
People are always looking for tips on how to do things better–particularly horse breeders looking for ways to get healthier foals. Benjamin Espy, DVM, Dipl. ACT, a practitioner from San Antonio, offered insight on many areas of equine reproduction
Drug compounding, the ethics of treating cryptorchids, and sexually transmitted diseases were the hot topics discussed by equine practitioners at the Reproduction Forum, led by Steven Brinsko, DVM, PhD, Dipl. ACT, associate professor of
Uterine torsion can be corrected using ropes, a plank of wood, and a burly volunteer, according to Laura M. Riggs, DVM, a clinical instructor of large animal surgery at the University of Georgia’s College of Veterinary Medicine.
It’s no secret that embryo transfer is expensive, and that its success rates are lower than those of some other methods of equine reproduction. “Commercially, single embryo recovery attempts have a 50% recovery rate, and there is a 50-65%
It’s common practice at some breeding farms–collecting the drippings from a stallion’s penis after he breeds and dismounts a mare, evaluating the sample to confirm that ejaculation did occur, then placing the sample in the mare. Reinforcement
The Biologic and Therapeutic Agents Forum at the 2006 AAEP Convention was facilitated by Craig Barnett, DVM, Intervet Senior Equine Technical Services Specialist, and co-facilitator Carol Clark, DVM, Dipl. ACVIM, of Peterson & Smith
