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.

“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?

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.
