I am trying feeding oat bales to my calves this winter. With the hay shortage it seemed to make sense. They were cut quite ripe and there is alot of oats in the bales. The calves seem to be doing fine but i was wondering if i could give them some rolled barley/wheat mixture as well or would that be to much. Other years they get fine hay and the grain but i know they are getting some oats from the bales. Also would the wheat added to the barley make it hotter feed?
