My main herd is steady eating 3 rolls of hay a day. That works out to 28 pounds of hay per head per day. I have never unrolled hay with success. Always ended up waisting too much to please me. I'm going to run smack out of hay, at some point in the future. I want to unroll one in the morning, and one in the afternoon. That's going to be 18 pounds of hay per day. I've never fed less, than free choice. What ramifications are there to feeding 18 pounds per day verses 28. By mid February, every cow in the field will get 6 pounds of ddg a day, until the green up. I could easily start earlier, if need be.
