Abstract:

本文旨在研究内蒙古牧区冬春季低质粗料供给条件下,补饲不同能氮比精料对羔羊生长性能及血清指标的影响。采取单因子试验设计选取(61±2)日龄健康、体重为(20.56±1.43)kg断奶的羔羊128只,公母各占1/2,分成4组,每组32个重复,每个重复1只羊,分别补饲消化能(DE)水平相近、粗蛋白质(CP)水平逐渐升高的4种颗粒精料,其能氮比(采用DE/CP)分别为90.03(Ⅰ组)、82.55(Ⅱ组)、73.25(Ⅲ组)、67.87MJ/kg(Ⅳ组)。试验期40d。结果表明:1)Ⅲ组平均日增重分别高于Ⅳ组7.75%(P<0.01)、Ⅰ组4.94%(P<0.05)和Ⅱ组3.41%(P>0.05),且该组料重比最优。2)Ⅰ组羔羊末体高极显著低于其他组(P<0.01),其中Ⅱ、Ⅲ、Ⅳ组母羔末体高分别比Ⅰ组高3.68%、4.12%、4.44%(P<0.05);不同能氮比精料对不同性别羔羊的胸围增长、胸围增长率无显著影响(P>0.05)。3)血清尿素氮含量随着精料蛋白质水平增加而升高,Ⅳ组极显著高于Ⅰ、Ⅱ组(P<0.01);Ⅲ组羔羊血清中白细胞介素-6含量显著高于Ⅱ、Ⅳ组(P<0.05),免疫球蛋白M含量显著高于其他各组(P<0.05)。结果提示,牧区冬春季枯草期对羔羊及时补饲精料能够取得较好的生长效果,不同能氮比精料对牧区羔羊部分血清指标产生显著影响,补饲精料最适能氮比为73.25MJ/kg。
