摘要
分别选用正大饲料羊精料补充饲料"584"(I组)和"自行研制加工的颗粒精料补充料(II组)对妊娠藏母羊从产羔前一个月至产羔后两个月进行补饲,以探讨不同精料补饲藏母羊对繁殖性能的影响。结果表明,试验I组、II组羔羊的初生体重、二月龄重、成活率均高于对照组,差异显著(p<0.05);试验I组与II组羔羊的初生重、二月龄重、成活率差异不显著(p>0.05);试验I组、II组每只羔羊收益分别比对照组提高2.3%、10.6%,经效益分析,试验II组投入低,效益好,饲料加工简单易行,方便在高寒农牧区藏羊生产推广应用。
The CTG concentrate supplement ＂584＂ （Group I） and Self-made pellet concentrate supplement feed （Group II） were selected in supplementary feeding pregnancy ewes from a month before lambing to two months after lambing in order to explore the effects of different pellet feed on the production performance of pregnant Tibetan sheep. The results showed that the lamb birth weight, two-month-age weight, survival rate of the group I and group II were significantly higher than those in the control group （P〈0.05）, which were not significantly different between group I and group II （P〉0.05） ; The income of each lamb increased 2.3% and 10.6% respectively in the group I and group II compared with the control group. Consequently, the benefit analysis suggested that the group II had low input, good benefits and simple feed processing which could be conveniently applied in Tibetan sheep pt＇oduction in alpine agricultural and pastoral areas.
