摘要
为研究苜蓿、羊草、燕麦、花生秧对肉羊的饲喂效果,选择膘情中等、健康无病、体重相近的5月龄杜湖杂交一代羊60只,随机分为Ⅰ、Ⅱ、Ⅲ、Ⅳ四个试验组,每组15只羊,分别饲喂以黄贮玉米秸秆+苜蓿干草、黄贮玉米秸秆+羊草干草、黄贮玉米秸秆+燕麦干草、黄贮玉米秸秆+花生秧为粗饲料的日粮,育肥60 d.结果表明,试验Ⅰ组羊的日增重最高,为193.56 g,分别较试验Ⅱ、Ⅲ、Ⅳ组高8.07%(P>0.05)、5.01%(P>0.05)和12.90%(P<0.05).试验Ⅰ组羊的屠宰率最高,达45.53%,显著高于其他3组(P<0.05).试验Ⅰ、Ⅱ、Ⅲ组羊的只均净收益分别比Ⅳ组羊高18.86元、17.11元和-8.69元.综上,饲喂苜蓿和羊草可以明显提高杜湖杂交羊的育肥经济效益.
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.
