Abstract: Allopatry fattening has become the main mode of beef cattle production in China.Scientific measures are expected to be taken to release the stress response of the purchased store cattle caused by long-distance transportation as soon as they arrive at the farm;the feeding and management during the transition period should be emphasized;for the purpose of precise feeding,the beef cattle individuals should be clustered into different groups according to their body weight,physical fitness and feed intake speed;for the store cattle with body weight lower than 200 kg,the crucial points of feeding are as follows:promoting the growth and development of skeleton,viscera and muscle,gradually enhancing the functions of digestive organs,providing the diet containing high-quality protein,offering appropriate concentrations of calcium,phosphorus,minerals and vitamin;for the store cattle with body weight ranging from 200 kg to 250 kg,high protein diet should be offered,and the abundant roughage should also be offered to stimulate the development of rumen;for the store cattle with body weight ranging from 250 kg to 300 kg,the diet should be composed of high-ratio roughage and complementary concentrate;when the body weight of the store cattle reaches up to 350 kg,the characteristic of the dietary nutritional requirement is that the protein content and energy level are recommended to be higher at the early and late stage of fattening period,respectively.The feed conversion ratio reduces with the increase of body weight for sale.Accordingly,the fattening strategies and marketing time of the beef cattle should be rationally applied and determined according to the fattening purpose,respectively.
