Most of our residents arrive with a body condition that would alarm a first-time horse owner. Decades of doing this — alongside guidance from our veterinarians — have shaped how we feed and rehabilitate every horse that comes through our gate. This page shares those standards, both for transparency with our supporters and as a resource for anyone caring for a senior or rescued horse.
Nearly every wild horse and feedlot rescue that has come through Whispering Winds has arrived underweight — some critically so. The instinct is always to feed as much as possible, as fast as possible. That instinct, if followed, can kill a starved horse. Overfeeding a severely malnourished horse can trigger refeeding syndrome — a metabolic crisis that can cause fatal heart, kidney, and respiratory failure.
Horses that have lost up to 30% of body weight can and typically do recover fully with careful refeeding. Horses that have lost more than half their body weight face a far harder road. The difference between recovery and tragedy is almost always the speed of that first week of feeding — which is why we treat "how fast can we fatten them up" as the wrong question entirely.
Our median resident age keeps climbing — we currently care for horses well into their 20s and 30s. Aging horses digest and absorb nutrients less efficiently than younger ones, and several of our residents, like RC in his day, are natural hard keepers who need extra calories just to hold a healthy weight.
Ginny was one of our Nevada Range mares — one of the fertility study horses, extremely underweight when she arrived. She and Susan built a close bond over a summer of rehab. In her later years, Ginny began losing her teeth. We started feeding her a soaked mash, which helped her hold her weight even as chewing became difficult. It's a pattern we've now repeated for nearly every senior horse in our care since.
Many of our older residents have "expired" teeth — worn past the point of being able to grind hay effectively. Left on long-stem hay, these horses lose weight, and risk choke or impaction colic trying to swallow forage they can't properly chew. The fix isn't more hay. It's different hay.
Based on guidance from our veterinarians and consistent with what's recommended across equine nutrition research, our go-to mash for a toothless or nearly-toothless senior combines:
Unsoaked beet pulp, which can expand in the gut and cause choke or impaction. Feeding beet pulp or mash meals too large or too infrequent. And for any senior showing signs of Cushing's (PPID) or insulin resistance, we switch to unmolassed beet pulp and low-sugar hay replacers, always in consultation with our vet.
Many of our senior horses are monitored for PPID and insulin dysregulation through regular bloodwork. Clinical signs like muscle loss, delayed shedding, or unusual fat deposits prompt a vet visit before we make any changes to feed.
Every practice on this page reflects both our own decades of hands-on rehabilitation and current guidance from equine veterinarians and nutritionists. We update our approach as veterinary science evolves — and we always defer to our own vets for any individual horse's specific needs.
