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

与对照组(未处理组)相比，双低菜籽皮经干式Na0H法、尿素氨化法、碱化-
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。

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
