I am trying to figure out how to background some calves this winter without buying either a mixer box or hauling more 5 gallon buckets. Usually we bucket them 3.5-4 lb grain (75 corn/25 DDG) and free choice grass/alfalfa hay. I talked to a Sweetpro rep today who said one lb of Sweetpro (Kalfkandi I think is the one he recommended) would likely take the place of about 3 lb grain. Wondering if anyone has used their products in a backgrounding situation and how it turned out. Thanks.
