Evaluation of a beef cattle finishing simulation model for intake and live weight gain prediction under different herbage and maize grain allowances

摘要：

Most animal grazing models require in advance measures or estimates of animal intake and feed quality to predict animal performance.An intake model linked to an animal performance model are the key components for whole‐farm simulation.Model evaluation is not a straightforward issue as individual herbage and maize grain intake are not always readily available.The objective of this study was to develop and to evaluate a beef cattle finishing model for predicting herbage intake and animal performance under different herbage and maize grain allowances.
