Aiming at the shortage of conventional BP algorithm, a BP neural networks improved by L-M algorithm is put forward. On the basis of the network, a predictive model for the future 305 days' milk productions was set up. The model can forecast 305 days milk quantitive production of the first birth cow ahead of 215 days. The validity of the improved BP neural network predictive model was validated through the experiments.
