“I used to build props and worked in film and television production, and I had a shop in my garage at home,” says Russ Gray, cofounder of Veterinary Simulator Industries (VSI) in Calgary, Alberta. “My neighbour was the dean for the University of Calgary’s new Veterinary School. He knew that I built weird things, so he asked me if I could build the back end of a cow just to garner some interest for the new school at the agricultural fair in Calgary. He wanted the back end of three cows so that kids could reach up into the rectum and palpate a calf’s head. I contacted my business partner, Bryan Pfahl, and we created them for him. At the time we were doing all kinds of jobs for science centres and things like that during the course of our careers, so we just took it on as another project.”

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.

Q: I own a top quality mare that I would love to have a foal out of. However, she is also my primary riding and competition mount, and I’d prefer not to stop riding her so she can have a foal. I do have another mare and am considering using her as a surrogate for embryo transfer. What exactly is involved in embryo transfer? How can I tell if my second mare is a good surrogate candidate?

How to Care for Your New Foal

Updated:

April 14, 2019

By Mark Andrews, DVM - You have waited eleven months for your foal to arrive. Now he is here what can you do to ensure he gets off to the best possible start in life? First thing's first. Make sure that the foal sucks. A normal foal should stand and drink from the mare within two hours. If the foal is having difficulty sucking, or is not interested, he may have serious problems. Call an experienced horse vet sooner rather than later.

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.

Effects of Longer Day Length on Pregnant Mares

Updated:

May 25, 2018

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.

In most cases, mares give birth quickly and without complications. The foal stands and nurses within an hour or two, and a few days later is following the mare around the pasture and snoozing in the sunshine. Sometimes, however, complications just before, during, or after birth can result in a decreased oxygen supply to the foal’s brain.

Research Targets Equine Herpesvirus

Updated:

April 12, 2018

Researchers at the University of Guelph are searching for clues to better manage a virus that can cause late gestation abortion in mares. Horses carrying equine herpesvirus (EHV) may exhibit signs as minor as a runny nose and mild fever, but the virus is a major cause of neurological, respiratory, and reproductive disease, including abortions, in the equine industry.
