摘要： 在高寒地区选择青海欧拉型藏羊在饲养管理完全相同且同等补饲精饲料［0.25 kg/（只·d）］的情况下，分组饲喂捆裹青贮燕麦饲草、全株玉米青贮饲草、燕麦青干草和小麦秸秆51 d。结果表明，捆裹青贮燕麦饲草（全干物质%）粗蛋白较全株玉米青贮饲草、燕麦青干草和小麦秸秆分别提高13.77%、94.23%和130.13%，粗纤维较全株玉米青贮饲草高52.35%，较燕麦青干草和小麦秸秆分别降低11.14%和26.73%；捆裹青贮燕麦饲草日均饲草采食量较燕麦青干草和小麦秸秆分别提高130.93%和199.58%，差异均极显著（P〈0.01），较全株玉米青贮饲草提高4.28%，差异显著（P〈0.05）；饲喂捆裹青贮燕麦饲草日增重达197.35 g/（只·d），较全株玉米青贮饲草提高10.85%，差异不显著（P〉0.05），较燕麦青干草和小麦秸秆分别提高40.96%和101.71%，差异均极显著（P〈0.01）；捆裹青贮燕麦饲草日均盈利1.71元/（只·d），较小麦秸秆、燕麦青干草和全株玉米青贮饲草分别多盈利1.17、0.96和0.50元/（只·d），分别提高216.67%、128.00%和41.32%。捆裹青贮燕麦饲草饲喂绵羊经济效益明显，在高寒地区可进行大力推广应用。

Abstract: This study aimed to assess the nutritional composition, feeding effect and feeding economic benefit of baled oat forage silage on sheep in alpine area. Qinghai Oula-type sheep were grouped and fed with baled oat forage silage, whole-plant corn silage, oat green hay and wheat straw, respectively. Each of the experimental sheep was offered a supplementary concentrate of 0.25 kg/d during the experimental period. All of the sheep were reared in the same feeding and management conditions, and the feeding experiment lasted for 51 days. The results showed that the crude protein content （dry matter %） of baled oat forage silage was increased by 13.77%, 94.23% and 130.13% compared to that of the whole-plant corn silage, oat green hay and wheat straw, respectively; the crude fiber of baled oat forage silage was increased by 52.35% compared to that of the whole-plant corn silage, and was reduced by 11.14% and 26.73% compared to that of the oat green hay and wheat straw, respectively; the average daily forage grass intake of the sheep fed with baled oat forage silage was significantly higher than that of the sheep fed with oat green hay, wheat straw and whole-plant corn silage, which was increase by 130.93% （P〈0.01）, 199.58% （P〈0.01） and 4.28% （P〈0.05）, respectively; the individual daily gain of the sheep fed with baled oat forage silage reached up to 197.35 g/d, which was increased by 10.85% （P〉0.05） compared to that of the sheep fed with whole-plant corn silage, and was elevated by 40.96% （P〈0.01） and 101.71% （P〈0.01） compared to that of the sheep fed with oat green hay and wheat straw, respectively; the individual daily feeding economic benefit of the sheep fed with baled oat forage silage was 1.71 Yuan/d which was 1.17, 0.96 and 0.50 Yuan/d more than that of the sheep fed with oat green hay, wheat straw and whole-plant corn silage, respectively, indicating the increasing rate of 216.67%, 128.00% and 41.32%, respectively. In conclusion, the baled oat forage silage has obvious feeding economic benefit in sheep rearing, and it is worthy of popularizing in alpine area.
