soaked beet pulp with a little grain and some corn oil really puts the weight on fast. Be careful to start with small amounts at first and gradually increase the amounts. Begin with 1/4 cup of beet pulp, soaked in water overnight with a handful of grain. The next week go to 1/2 a cup, next week add a tablespoon of oil. You just have to be careful with any diet change. I took care of a horse for awhile that was brought over in the middle of winter and very thin. I was up to 1 1/2 cups of beet pulp and 1/2 cup of oil, with a handful of oats for flavor, by the end and he looked shiny and a good weight. I believe, someone correct me if I am wrong, not only is this an economical way to go but less likely to make them hot than the expensive feeds.
