Calculate a ration for a mature, pregnant cow weighing 1250 lbs using the same feeds. Her dry matter intake is expected to be between 18.75 and 25 lbs. Her CP requirement is 1.47 lbs and her TDN requirement is 10.51 lbs. (What if our hay was different, say fescue with 7% CP? Calculate a 2nd ration with this hay - 55% TDN, 7% CP)
