Research of nutritional regulation of growing and fattening in beef cattle

The regular pattern of nutritional self-regulation in animals'bodies can be completely mastered and used.In the practice of beef cattle feeding and fattening,the distribution law of nutrient substances in vitro in beef cattle can be used to regulate the condition and the composition of meat.Major regulatory measures include the structural control technology for dietary nutrients,changing feeding system and using nutrient regulation reagents of tissue metabolism and etc.This paper focuses on the research of regulation technology of nutritional engineering in growing and fattening beef cattle.
