we raise sheep and some beef cattle,soIm not sure of dairy ration. THE DHIA has all sorts of rations because ususally the dairy herds are in the 200 to 1000 cow range round here. Most of the dairy farmers I know use a combination of corn chop and cob all made into silage. They also feed grass hay with a free choice for mineral salts. I dont like salt blocks because sheeps dont chew, so we mic=x he minerals right into our grain mix.
WE get our mixes made freom corn, oats, mineral mix and dry molasses . My wife keeps the reipe but its not difficult, corn for energy and oats for protein. We also feed alfalfa or grass hay (depending on the season)
