摘 要：
为研究玉米粒度对滩羊羔羊养分消化率的影响,选择体重相近的4月龄滩羊公羔24只,随机分为2组,每组12只。在饲料组成完全相同的基础上,试验组羔羊饲喂整粒玉米,对照组羔羊饲喂粉碎玉米。结果表明,玉米粒度对滩羊羔羊日粮干物质、有机物、粗蛋白和中性洗涤纤维的表观消化率影响差异均不显著(P>0.05)。提示生产实践中滩羊羔羊日粮中的玉米可以不经加工处理,采用整粒形式投喂。

摘 要：
In order to study the effects of corn particle size on nutrient digestibility of Tan Sheep lamb, a total of 24 four-monthold male Tan Sheep lambs with similar weight were chosen and randomly divided into two groups with 12 lambs for each group.On the basis of the same feed composition, the experimental group fed whole corn, and the control group fed crushed corn. The results showed that there were no significant effects of corn particle size on the apparent digestibility of dry material, organic matter, crude protein and neutral detergent fiber of lambs(P >0.05). The results indicate that it is unnecessary to process the corn in lamb diet, and the whole corn can be fed directly.
