Looking at some options for supplementing my cows this winter. Im considering soy hulls, corn gluten and whole cottonseed. The wcs seems like the most bang for the buck but i currently do not have a way to store it unless i store on tarp and cover with another tarp. Will that work? Is a soyhull corn gluten mixture ok or would i be better with just soyhulls? I also have the option of a wcs in pellet form but its pretty pricey. I know pulling analysis of my hay to see exactly what i need would be the best option, but what have yall found that seems to work? The cows do have fall born calves on their sides. Thanks in advance
