Well I am not sure if she eats 50lbs a day that's what is given to her but she is below the other horse. She most likely eats around 40 lbs a day. She was also rescued last fall so I also wonder if all the worms were ever taken care of in the first place.
She currently gets a ration balancer and cool calories and last week she was started on alfalfa (up to just under 1 lb currently) with her rb at night and she gets the barn's grain in the morning.
I'm waiting on the vet to call me back still, he's busy today.
The hay she was on was not good, but within the last 3 weeks has been switched over to a better supplier. She was only getting 4 flakes of the bad hay twice a day which was about 15 lbs a feeding until almost 2 weeks ago when the hay was increased. Her teeth were floated last fall as well and she lets me open her mouth and they all look great still, she has no issues with a bit as well.
She has tons of energy, just won't put on the weight. She is also 18 or 19 which might be a factor.
Thank you for any responses.
