摘　　要：本试验选择2.5周岁的中国西门塔尔—太行类群牛公牛40头,随机分为两组(P>0.05),进行全株青贮与黄贮强度育肥对比试验。试验组饲喂全株青贮,对照组饲喂黄干青贮,在饲养管理和精料饲喂量完全相同的情况下,经过50d的育肥试验,试验组日增重达1337g,比对照组日增重1051g提高了27.2%(P<0.05)。试验组头均纯收入5638.6元,比对照组3418.6元提高了64.9%。结果表明应用全株青贮饲喂肉牛,经济效益明显。The 50 days fattening experiment with the same condition of feeding management and concentrative feed amount was conducted with 40 Chinese Simmental - Taihang taxa bulls（2.5 years old）,which were selected and divided randomly into 2 groups：test group was feed whole-plant corn stover silage,control group was feed green corn stover silage,under the condition of feeding management and concentrative feed amount, The average daily gain of test group were 1337g,increased by27.2%（P0.05） compared with the control group （1051g）,average revenue of a cattle in test group were 5638.6 yuan,increased by 64.9%（P0.05） compared with the control group,It was concluded that the economic benefit of grazing with whole-plant corn stover silage feeding was significant.
