I have a 5 y/o working cow horse that is boarding about a half hour from me. Being boarded my choices on feed are limited because they generally only feed supplements once a day and only supply alfalfa hay. With that being said, my horse is on alfalfa 2x a day with unlimited salt and water access. I give her one pound of renew gold daily as well. She gets bored with food very easily and won't eat her renew gold anymore. She was on triple crown in the past and became tired of that too, and I didn't like it anyway. Is there any recommendations? She is in training and is being ridden often, I want her to have a healthy weight and feel and look as good as possible! Thank you!
