Abstract: Based on the feeding experiment and investigation of reproduction cows,sucking calves,and feeder cattle,combing with the fattening experiment of feeder cattle and the linear fattening experiment of calves,referring to Feeding Standards of Beef Cattle and the reported data of fattening experiment of beef cattle,the feed grain needed in the productions of beef products in different fattening process of beef cattle were compared according to the supply situations of beef products and the feed resource situations of fattening beef cattle in China.The results showed that less grain were consumed by linear fattening technology than concentrated fattening in late stage to obtain the equivalent weight of beef products.And more feed grain needed to be consumed in the production of high-grade beef.
