提高双低菜籽皮对反自动物营养价值的研

摘要

本研究以双低菜籽皮的中性洗涤纤维(NeutralDetergentFiber，NDF)含量为评

定指标。采用混合嵌套设计从干式NaOH法(处理时间分别为d1、d2、3d)、尿素

氨化法(处理时间分别为1d0、1d5、ZOd)、碱化一氨化复合处理(处理时间分别为

15d、ZOd、25d)筛选出最佳处理组及其处理时间;采用L(3‘)正交设计筛选出最

佳配比的纤维素酶、B一葡聚糖酶、木聚糖酶和a一淀粉酶处理组;从而得到最佳化学

处理组和最佳复合酶制剂处理组。采用扫描电子显微镜(SacunnigEleetrno

Mcriosocpe，SEM)技术分析上述最佳处理组处理的双低菜籽皮的结构;并分别以

稻草、未处理双低菜籽皮、经最佳化学组处理的双低菜籽皮、经最佳复合酶制剂组

处理的双低菜籽皮为粗料配制不同日粮，研究其对湖北麻城黑山羊的生长性能的影

氨化复合法处理后中性洗涤纤维(NDF)含量降低，中性洗涤纤维2h4降解率升高。

双低菜籽皮经不同化学方法处理后，中性洗涤纤维(NDF)含量组间差异极显著

同种方法不同时间处理后，时间对NDF含量及中性洗涤纤维24h降解率的影响是极

低菜籽皮表面光滑，“孔穴”结构更加规则，并且细胞器基本完全解体脱落。表明双
