日粮制粒对绵羊利用玉米秸秆的影响

Effects of Diet Pelleting on Corn Stalk Usage by Sheep

[目的]研究颗粒料对绵羊生产性能、经济效益及秸秆消化率的影响。[方法]将玉米秸秆与混合精料混合并添加营养性添加剂,在此基础上制成颗粒料,分别饲喂2组小尾寒羊,测定各营养物质的采食量、消化量和消化率。[结果]结果表明,日粮制粒能明显地提高绵羊对玉米秸秆的利用率和绵羊的生产性能。[结论]该研究制备的颗粒料能大幅度促进绵羊的生长。

[Objective]The research aimed to study the effects of diet pelleting on the production performance,economic benefit,stalk digestibility of sheep.[Method]Diet pelleting was made with corn stalk,mixed concentrate and nutritive additive.And two groups small-tailed Han sheep were tested in feed intake,digestion amount and rate after fed with diet pelleting.[Result]The results showed that diet pelleting could obviously improve the stalk utilization ratio and production performance of sheep.[Conclusion]The diet pelleting made in this study could greatly promote the growth of sheep.
