We are only a few weeks away from grass, but have ended up with most of our remaining hay supply to be 2nd cutting alfalfa. We have a limited supply of grass bales, and I have been feeding both bales for a few days now. I can only continue feeding grass for about 3 more days and am wondering how long it takes beef cows to transition to strait alfalfa hay without risking bloat? We have wheat straw which I can put out as well but can only mix manually or leave in bale rings, which I at least plan to do. Also, once feeding strait alfalfa should I continue to let them have access to it rather than forcing them to clean it up, therefore not letting them get too hungry and overeat. Any advice would be helpful, thanks.
