Breeding an older mare might require some extra work by the owner and veterinarians. In this video, equine reproduction specialist Dr. Maria Schnobrich talks about considerations for breeding an older broodmare.

Since 2012, Schnobrich has worked as a theriogenologist at Rood & Riddle Equine Hospital with a primary focus on problem mares and stallions. She practices ambulatory reproduction and advanced reproductive techniques. She has been involved in several research projects collaborating with colleagues locally and nationally. Schnobrich’s interests include diagnostic methods for the problem mare, enhancing reproductive success in both sexes, and evaluating field data to assess practices that enhance reproductive efficiency.

Hands-On Exam for Older Mares

“When we are having a conversation about how I can best advise you on what breeding program and what options are available for you, I really need to see the [older] mare,” said Schnobrich. “If I look at one that is in poor health or not metabolically healthy, there’s a lot of work we need to do before we even start talking about what our reproductive options are.”

Schnobrich will do a hands-on exam of the older mare’s reproductive tract and her conformation.

An older animal that has “really kept her topline,” has excellent perineal conformation, and is healthy overall might be a straightforward management proposition.

Physical Issues

“I have a very skinny mare that has lot a lot of muscle tone and has regional areas of adiposity [fat pads] suggestive of metabolic dysfunction, that’s going to be concerning to me,” she said. That is not only because of reproductive tract issues, but oocyte quality.

Schnobrich said there are supplements and other things available that can be used to optimize the older mare’s oocyte function and capability.
