To improve the efficiency of feed utilization and reduce the feeding cost, we proposed a feed formulation method based on Differential Evolution algorithm. Individuals were constructed according to the content of each raw material in the feed formulation and the lowest feed formulation cost was taken as the objective. The feed formulation was solved by Differential Evolution algorithm. Using NRC (2001) prediction model of main nutrient requirement of dairy cows and the data of common feed of dairy cows in China Feed Database, we carried out the experiment of feed formulation for lactating dairy cows. Compared the feed formulation result of our method with those of Linear Programming method, our method performed better.
