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。

Abstract: 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.

Key words: dietary concentrate to forage ratio; Tibetan lamb; daily gain; feed efficiency
