[QUOTE="hayray, post: 623596, member: 3046"] TDN values are better used for balancing cow rations. For feeders better to use Net energy and CP values. Feed high energy concentrate (corn) guessed at 8% protein and at 80% of total dry mater intake and feed hay to match at 20% Dry matter intake and feed to match 3% of body weight of dry matter intake/day. You can test your hay or make assumptions of hay CP % and then from there see if you need to add any protein to bring overall dietary protein up to 12% of diet. Often while feeding a grass mix hay you can add a half pound/head of protein per day to make up for it -- for example - 1 pound per head per day of soybean meal at 48% protein gives you an extra half pound per day. MSU is having a cattle feeding program tonight up at the pavillion on campus at 6:30. [/QUOTE]
