I am looking to formulate a ration to feed on dormant bluestem in the wintertime. There is alot of volume of grass but the protien is low. The ration needs to be built around ground cotton burs and whole cottonseed. What other ingredients are needed and in what proportion? Does anyone have a "recipe"? I have a mixer truck to mix the ingredients. I want to feed 500 to 700 lb. stockers. Thanks!
