I just got my first horse and am wondering about the best feeding for him. His previous owner fed him grass hay/alfalfa mix and during the winter months she added grain (Safe Choice by Life Design). I believe he has also been on straight grass hay, but availability caused her to switch to a mix.
At our barn, he is currently getting grass hay/alfalfa mix 2x per day and a small amount of grain (not sure the exact kind, our barn provides basic feed with boarding). I have been told and read here a lot of differing opinions on alfalfa and grains. Part of me has the attitude, "if it ain't broke, don't fix it", so as long as he seems to do well I should just keep it the same, but I want to do the right thing. I also wonder about a specific senior feed being important.
He is an 18 yr old arab/QH cross. Currently he gets worked/ridden (light work) about 1-2 hours per day. What would be a good, basic diet for him?
