help old horse gain weight
I have a 26 year old standardbred, Maggie she is pastured with two lively and fat quarter horses on limited turnout. She became depressed over the winter, she was at home by herself and lost a lot of weight even though she was on free choice hay, 24 hour turnout and pretty much all the grain she could want. Right now she is a bcs scale 3.5 or so. She is on 4 pounds of nutrena life design senior, and we just added 1/2 pound of nutrenta 10 10 sweet feed, but are building her up to 2-3 pounds, and about 1/2 cup of corn oil. The problem with her is that she sometimes won't eat. If we try to feed her in the morning, more grain she won't eat. What we are feeding her now is pretty much the max she will eat. Her and her pasturemates are out for 4 hours in the morning and 3 hours at night. We also put Maggie out at night with her grain hopeing she will eat more grass. She has no worms: fecal egg count followed up with deworming and retest. And her teeth were checked by an equine dentist and very good condition. What do I do to put more weight on her?
