Warmblood Fragile Foal Syndrome Type 1 (WFFS) is an inherited defect of connective tissue characterized by hyperextensible, abnormally thin, fragile skin and mucous membranes that are subject to open lesions. Affected horses may also have hyperextensible limb joints, floppy ears, accumulation of fluid (hydrops), subcutaneous emphysema, hematomas, and premature birth. The disease is present at birth and affected newborn foals are euthanized shortly after birth due to the poor prognosis of this untreatable condition.

Testing Now Available - Researchers at the UC Davis School of Veterinary Medicine have identified a genetic cause for the fatal condition, equine familial isolated hypoparathyroidism (EFIH), in Thoroughbreds, marking the first genetic variant for hypoparathyroidism identified in any domestic animal species. Additionally, this is the first widely available genetic test for Thoroughbreds.

A poll on HORSEJournals.com asked the question: Should equines be cloned? Some 83 percent of respondents said no, not until more research has been done; 15 percent said maybe, in special situations with strict parameters; just two percent said yes, and that registration of clones should be allowed.

On August 6, 2020, a cloned Przewalski’s horse foal was born at the Texas veterinary facility, Timber Creek Veterinary, a long-time collaborator with ViaGen Equine in Cedar Park, Texas, a world leader in cloning services. To bring a cloned Przewalski’s foal into the world, they worked together with San Diego Zoo Global’s Frozen Zoo, and Revive & Restore, a conservation organization promoting biotechnology in conservation techniques.

Genetic Study Challenges Common Beliefs - A study involving Arabian horses from 12 countries has found that some populations maintained more genetic diversity and that the breed did not contribute genetically to the modern-day Thoroughbred, contrary to popular thought.

A possible new treatment for foal pneumonia that doesn’t risk causing multi-drug resistance has been discovered. Researchers at Texas A&M University and the University of Georgia found that gallium maltolate (GaM), a semi-metal compound with antimicrobial and anti-inflammatory properties, could be a viable alternative to overprescribed antibiotics. The research, funded by the Morris Animal Foundation, has been published in the Nature journal Scientific Reports.

Keyhole Vasectomy for Standing Horses, breeding stallions, laparoscopic technique standing horse, equine science update

Male horses are usually castrated to moderate unwanted male behaviour and limit unintended reproduction. Vasectomy, interrupting the vas deferens to prevent sperm being released, is an option to prevent breeding while still maintaining male behavioural characteristics. It is performed less frequently in horses than in other species.

By Juan C. Samper, DVM - Endometritis, which is the inflammation (swelling and irritation) of the uterus, is the main reason for mares not becoming pregnant. This inflammation can be acute or it can be chronic; in other words, this inflammation could be something that is occurring for the first time or it could be a problem that has been going on for a long time.

Morris Animal Foundation’s $2 Million Research Investment Offers Hope for Horse Lovers - After decades in the making, a vaccine against deadly foal pneumonia might finally be within reach, thanks to Morris Animal Foundation-funded research conducted at two major universities. The breakthrough could potentially save the lives of thousands of foals every year.

Artificial light has been used to mimic longer day length and hasten the onset of seasonal reproductive activity in mares. Extending the day length to about 16 hours is now a common management tool on horse breeding farms.
