I have a 15.3 hand QH mare that is 12 years old and on a medium workout routine with trail riding and reining. She is ridden about 4 times a week for 1-2 hours and shown or trail ridden on weekends for about 2- 4 hours.
She has had her teeth floated and is on a 2 month dewormer rotation schedule.
She gets fed twice a day with 5 lbs of 10% pellets at each feeding and all the hay she can eat (our hay is very good quality).
She seems too thin and I am worried about her, I can see her ribs.
I have tried Farnam Weight Builder for 3 months and it didn't help at all. I have also tried Purina Amplify for 2 months and did not see a change in her weight.
Would you please tell me how much weight you think she needs to gain and if you have any feeding suggestions?
I know this photo is not the best(she is leaning to far forward) but it was the only one I could find right now...
