摘 要:试验旨在研究日粮精粗比对羔羊增重的影响,为育肥羔羊日粮合理配制提供理论依据。选择90只2月龄藏羔羊,随机分为3组,分别饲喂精粗比为7∶3、6∶4和5∶5的3种日粮,试验期120 d。结果表明,羔羊日增重随日粮精粗比的提高而增加(P<0.01),提高日粮精粗比能有效提高饲料利用效率,精粗比为7∶3的日粮饲喂藏羔羊经济效益较好。The experiment was conducted to study the effect of different dietary concentrate to forage ratio on gain of Tibetan lamb and aid to provide a theoretical foundation for compounding dietary in Fattening lambs.90 two-month age Tibetan lambs were selected and divided randomly into 3 groups,and fed dietary with different concentrate to forage ratio of 7∶3,6∶4 and 5∶5,respectively.Experiment period was 120 days.The results showed that the lamb daily gain increased with dietary concentrate to forage ratio increased(P〈0.01),the feed efficiency was increased with dietary concentrate to forage ratio improving.Economic profit was best when the ratio was 7∶3.
