Balance a ration for a 700 lb. calf, on a dry matter basis, that requires 2.3 lbs of cp and 15.1 lbs of tdn. the dry matter intake is expected to be about 15 lbs (so don't feed more). feed 1% of the animals body weight as hay (dry matter), and use corn and soybean meal to meet the remaining needs (if any).
use
corn: 10% cp 90 %tdn 88% dm
forage 12% cp 55% tdn 84% dm
sbm 50% cp 88% tdn 90% dm
then convert to as-fed amounts
dm of forage=
as fed of forage=
dm corn=
as fed corn=
dm sbm=
as fed sbm=
