Abstract

Data from 325 treatment means in 35 previous beef cattle feeding studies were used to evaluate the 1996 NRC model for accuracy of gain predictions and to develop predictions of net energy adjusters for use with the model. The model was found to inaccurately predict gain of cattle fed diets varying in ingredients and energy density. Net energy adjusters were used to achieve accurate prediction of gain for each observation and then equations were developed for predicting the level of net energy adjustment required to improve accuracy of gain prediction.
