Feed is one of the greatest costs of beef production. Most of the feed used annually by a cow is to maintain her body. A study was conducted measuring individual feed intake of mature pregnant cows. We have determined that the amount of energy that a cow uses to maintain her body is heritable suggesting that cows can be selected for differences in the energy required to maintain their bodies.
