It works in a lot of situations.. keeps them on feed, holding rations, helps to loosen up or deepen tighter gutted animals, gives you good fill when you need it. However, it is not something you want to use a lot of if you are pushing for weight gain.
We feed it at a very low rate to start out with & then increase as needed. We also might pick it up a bit for the weekend of a show and then drop it off some when we get home.
Just a side note.. BCCC, have you ever put some in water to see how much it expands? Kinda cool. I have a customer who had the roof ripped off of her barn during a tornado earlier this year. Apparently a couple bags of soaking wet Full Tank are a sight to see.
