With massive and intensive development of Chinese live pig industry, the imbalance of feeding nutrition turns out to be a primary problem. The main reason is that the nutrition needs to be adaptive to live pig’s exact growth conditions in production management process. Regarding this, the paper aims at developing a feeding selection model for pig breeding based on major nutrients predictive model proposed in the Nutrient Requirements of Swine published by U.S. NRC in 1998. The objective of this model is to achieve a minimum cost of feeding stuff under the premise that the nutrients satisfy pig’s needs. According to values proposed in NRC and nutritional elements data, a feeding selection model was developed to give proper suggestions on feeding dietary nutrients as well as exact type and quantity of pig feeding stuff. The work presented in this paper would contribute to the optimal precision feeding strategies so as to guarantee live pig growth quality in management process.
