Thanks for all your input. My horses are not really in need of weight gain, and a few pounds to wear off in the spring is just fine. Beet pulp is too processed for me to consider unless we have an underweight issue. Our nights get to
-25 C, and they are eating their free choice hay faster than usual. I will start with a couple of pounds a day, and see how they make out. They also have free choice Hoffman minerals, I am not worried about balanced ration. Thanks again!
