摘要: Routine methods for predicting animal performance use in livestock management are changing. Static systems of feed requirements beginning to be replaced by dynamic simulation models able characterise response a wider range input conditions than those accommodated traditional systems. This paper summarises work conducted over the last seven years aimed at developing growth. The has been based on assumption that critical determinants growth identified causal representing factors associated with cellular hyperplasia and hypertrophy can aggregated whole level will result greater accuracy application is usual more empirically defined models. methodology used model development described elsewhere [ 241.
