I've got an elderly (30 yrs) quarter horse mare who within the last month or so has declined most feed. She eats about 5 lbs of equine senior a day but will not eat beet pulp, hay pellets (orchard grass, timothy or alfalfa) or grass hay. She has access to feed and water at all times. We've done tests for liver and kidney function and they are close to normal. We're trying steroid injections and we're treating her for possible ulcers from not eating enough. Clearly she will not survive the winter at the current rate.
Does anyone have experience with a similar problem. Any suggestions on feed to try?
Maybe she's just come to the end of her life and is shutting down.
