Abstract

Data from 277 treatment means in 15 previous beef cattle studies were used to develop equations to predict net energy adjusters throughout the feeding period to better predict gain with the National Research Council’s 1996 Nutrient Requirements of Beef Cattle model. Early in the feeding period the net energy adjuster reduces the energy to correct for overprediction of gain and late in the feeding period the net energy adjuster increases energy to correct for under prediction of gain. The average NE adjusters were 0.88 and 1.08 for the beginning and end of the feeding period.
