不同饲草对杜湖杂交羊饲喂效果的影响
Feeding Effect of Different Roughage Forages on Hybrid Offspring of Dorper Sheep and Hu sheep
摘要
Abstract
In order to study the feeding effects of alfalfa,Leymus chinensis,oats,and peanut seedlings on mutton sheep,60 5-month-old hybrid F1 lambs of Dorper sheep and Hu sheep with medium fatness condition,healthy,disease-free,and similar weight were selected and randomly divided into four experimental groups Ⅰ, Ⅱ, Ⅲ,and Ⅳ,and 15 sheep in each group.Groups Ⅰ,Ⅱ,Ⅲ,and Ⅳ were fed with a diet consisting of yellow stored corn straw+alfalfa hay,yellow stored corn straw+ Leymus chinensis hay,yellow stored corn straw+oat hay,and yellow stored corn straw+ peanut stalk as coarse feed,fattening for 60 days.The results showed that the daily gain of group I sheep was the highest,at 193.56 g,which was 8.07%(P>0.05),5.01%(P>0.05),and 12.90%(P<0.05)higher than that of group Ⅱ,Ⅲ,and Ⅳ.The slaughter rate of group I sheep was the highest,reaching 45.53%,significantly higher than the other three groups(P<0.05).The net income of sheep in experiment Ⅰ,Ⅱ,and Ⅲ groups increased by 18.86 yuan,17.11 yuan,and-8.69 yuan compared to group Ⅳ.In summary,it indicated that feeding alfalfa and Leymus chinensis could significantly improve the fattening economic benefits of hybrid F1 lambs from Dorper sheep and Hu sheep.关键词
