Aiming at the shortage of conventional bpalgorithm,a bp neural net works improved by L-M algorithm is put *** the basis of the network,a Prediction model for 305 day's milk productions was set *** methods finish these data must spend at least 305 days,But this model can forecast first-breed dairy's 305 days milk production ahead of 215 *** validity of the improved bp neural network predictive model was validated through the experiments.
