I live in KY and have 17 heifers around 18 months old and one bull. My brother and I started back in Dec. 2011. He said that one should allow 7-10, 4-foot rolls of hay per cow during winter. This year however, ours averaged 2.5 rolls. The winter wasn't harsh, and we did let them roam a wide territory instead of having them more confined. Nonetheless, I was amazed at how little hay they ate. We didn't feed anything else. Did anyone else in KY or surrounding states get by with less hay this year?
