摘要/Abstract

摘要： 将20只藏系羯羊(1岁)分为Ⅰ、Ⅱ、Ⅲ、Ⅳ 4个处理组，Ⅰ、Ⅲ、Ⅳ组分别用150、300、450 g/(d·只) 3种精料添加水平，自由采食干披碱草，Ⅱ组添加青贮料，以研究不同精料添加量和青贮料对藏羊生产性能的影响。试验结果表明，4组藏羊全期平均日增重分别为(41.00±5.48)、(63.00±8.37)、(68.00±9.75)、（69.00±9.2） g，Ⅳ组极显著高于Ⅰ组（P＜0.01）；Ⅱ、Ⅲ组显著高于Ⅰ组（P＜0.05）；Ⅱ、Ⅲ、Ⅳ组间差异不显著(P＞0.05)。在本试验日粮条件下，每天每只饲喂300 g（Ⅲ组）精料时的饲料转化率最高，青贮料比Ⅲ组更为经济。

Abstract: 20 castrated Tibetan sheep which were randomly divided into four treatments (group Ⅰ, group Ⅱ, group Ⅲ and groupⅣ)were adopted to investigate the effect of different concentrate levels(150，300，450 g/d) and silage on production performance． The results indicated that average daily gain(ADG)of four groups were （41.00±5.48），（63.00±8.37），（68.00±9.75），（69.00±9.2） g respectively．ADG of group Ⅳ was higher than that of group Ⅰ，significantly(P<0.01), ADG of group Ⅱ and group Ⅲ were higher than that of group Ⅰ，significantly(P<0.05), there was no significant difference among group Ⅱ, group Ⅲ and groupⅣ. The highest feed efficiency showed at 300 g/d concentrate leve1(group Ⅲ), and group Ⅱ (the silage) showed to be more economical than group Ⅲ.
