不同肉牛育肥的牛肉产品生产对饲料粮消耗比较分析

在对繁殖母牛、哺乳犊牛和架子牛进行饲养试验及调查的基础上,结合所进行的架子牛育肥试验和犊牛直线育肥试验,参考肉牛饲养标准和已发表的肉牛育肥试验数据,并根据目前我国牛肉产品提供状况和肉用牛育肥的饲料资源情况,分别比较不同肉牛育肥牛肉产品生产所需要的粮食。结果表明,为获得等同重量的肉牛产品,直线育肥技术比后期集中育肥要消耗较少的粮食,而高档牛肉生产（高端肉产品生产）需要消耗更多的饲料粮。

Comparative Analysis of Feed Grain Consumption in Different Beef Production of Fattening Beef Cattle

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.
