Right now she's on full turnout (though the quality of grass is iffy this year - not much rain in my area until recently), and getting about 2lbs per day of HiFat20, 4 scoops of Cool Calories, 4lbs of Alfalfa pellet, 1lb of beet pulp(dry weight) (all per day). It seems to be about the most we're able to get her to eat (even if it's broken down to several feeding in a day). I've also just started her on "Recovery" to see if that might help her apparent stiffness. (When she's at a show her grazing is replaced by free choice, quality low sugar hay with 12% protein)
The vet has seen her, and doesn't have an "answer" for why she wouldn't be eating enough to keep weight on her. She is otherwise seemingly healthy (bright, alert, willing to work - though stiff). Her blood pannel came back fine - a little low in some minerals (so that's been increased), and her teeth are OK (she'll be floated soon anyhow, but nothing he felt was going to cause this problem).
I'm wondering if there's another feed I can add, or replace what we're already giving her with, that people will "swear by" ? (she's a little fussy, but not too bad)
She's a 13yr old American Saddlebred, probably about 900-1000lbs at a "good weight" (she's a little under that right now) - she's never been a really hard keeper before (she's new to us, but her previous two homes swear she wasn't - and they are both honest people), though she is working harder than she ever used to. What baffles me most is that she won't eat "more" feed - but still won't put weight on. Her workload has been decreased as well.
