青贮玉米盘江7号对肉羊增重效果的研究

为探讨玉米盘江7号青贮秸秆对肉羊增重效果的影响,采用全舍饲喂养的方式比较饲喂玉米盘江7号青贮秸秆和风干玉米秸秆对肉羊的增重效果。结果表明:试验期内供试羊在其他饲养管理水平完全一致的情况下,试验组(所喂粗饲料为玉米盘江7号青贮秸秆)日均增重达213.44g/只,对照组(所喂粗饲料为风干玉米秸秆)日均增重150.78g/只,试验组日均增重比对照高62.66g/只(P<0.01)。试验组只均盈利达228.38元,对照组为131.54元,试验组只均盈利比对照组提高73.62%,经济效益提高明显。

Effect of Feeding of Corn Straw Silage of Panjiang No.7 on Weight Gain of Fattening Sheep

In this study,the effect of feeding of corn straw silage prepared with Panjiang No.7 and air-dried corn stalk on weight gain of fattening sheep under fully confined rearing condition was evaluated and compared.The results showed that under the same feeding and management condition,the average daily gain of individual sheep fed corn straw silage prepared with Panjiang No.7 was 213.44 g,which was 62.66 g higher than that fed air-dried corn stalk (150.78 g).During the feeding experiment,the average economic benefit for individual sheep fed corn straw silage prepared with Panjiang No.7 was 228.38 Yuan,which was increased by 73.62% compared to that fed air-dried corn stalk (131.54 Yuan),indicating an obvious improvement of feeding economic benefit.
