I would go w/ peggysue. she was right-on with her suggestions for my boy. i'm planning to post some before and after pix soon. the difference in weight, poop, and over all health is absolutely amazing. I don't know the horse but my geuss would be he probably needs approx. a full bag of TC Senior per week. I havne't marked on a calendar but it seems like for 2 senior horses I"m going through about 10 bags of grain every three weeks.....
