摘要
本试验选用4月龄滩羊60只,随机分为两组,即对照组与试验组。对照组羊只饲喂基础精料700 g,试验组饲喂600 g基础精料+200 g大麦。粗饲料均为苜蓿和玉米秸秆,玉米秸秆自由采食。试验期间定期称量试验羊只体重与耗料量,以研究日粮中添加大麦对滩羊生产性能的影响。结果表明:日粮精料中添加大麦对滩羊的生产性能有明显的促进作用。其中,试验组滩羊在整个试验期(62 d)的总增重、平均日增重均极显著大于对照组(P<0.01),分别比对照组增加1.53 kg(P<0.01)、24.58 g(P<0.01)。此外,试验组料重比为7.08,比对照组7.75减少了0.67。说明,滩羊精料中添加大麦有益于提高其生产性能。
To investigate the effect of adding barley in diet on the performance of tan sheep,sixty four-month old tan sheeps were randomly divided into two treatments （namely control group and experimental group）.The tan sheeps in con-trol group feed 700 g basic concentrate and feed 600 g basic concentrate with 200 g barley in expermental group.Alfalfa and corn straw were used as roughage both in the two groups,measured the daily gain and F/G （feed to gain ratio）during the experimental period.The result showed that added barley in daily concentrate can improve the production performance of tan sheep.Both the total gain and daily gain of experimental group were significantly improved compare with the control group（P 〈 0.01）.The total gain and daily gain of experimental group were respectively increased 1.53 kg（P 〈 0.01）, 24.58 g （P 〈 0.01）.In addition, F/G of experimental group was 7.08 lower than control group 0.67.The results indicated that adding barley in daily concentrate is beneficial for the production performance of tan sheep.
