What does everyone feed for Protein this time of year? We are calving spring calvers and have fall cows with big calves on them. We have been feeding about 3-6 # of good alfalfa hay along with grazing stockpiled fescue, or feeding hay in some pastures. Just curious as to what other use. Cubes, Alfalfa, tubs??? What do you use and how much/hd/day?
