不同处理豆粕日粮对舍饲羔羊生产性能的影响

The Influence of Different Processed Soybean Meal on the Feeding Lamb Performance

试验研究了不同处理豆粕日粮对舍饲羔羊生产性能的影响。结果表明,饲喂膨化豆粕日粮组和饲喂膨化豆粕+加酶益生素日粮组,舍饲羔羊的平均日增质量分别比饲喂羔羊常规日粮对照组提高32.61%,44.35%;饲料转化率提高6.72%,5.70%;植物性蛋白源饲料豆粕经膨化和添加加酶益生素后能有效去除和降解抗营养因子和过敏原,减少对羔羊消化系统的刺激,适应其消化生理特点,可提高舍饲羔羊日增质量和饲料转化率。充分验证了舍饲羔羊应用植物性蛋白源饲料营养调控的效果和必要性。

The paper investigated the influence of the different treated soybean meal on the feeding lamb performance. The results showed that the average daily gain of feeding lambs in experiment I group （feeding with extruded soybean meal） and experiment II group （feeding with expanded soybean added probiotics ration） increased by 32.61% and 44.35%, and its feed conversion rate （FCR） increased by 6.72% and 5.70%. Especially in the early weaning, the lamb weaning stress symptoms and the rate of diarrhea were reduced by feeding with extruded soybean added probiotics total mixed ration. And it played an important role on cultivating strong lamb, improving the level of breeding sheep, and showing excellent lamb performance. It fully verified the effect and the necessity of vegetable protein feed source after applying nutritional regulation for feeding lamb.
