固相酶解技术在动物粪处理领域的探讨

摘要

Poultry manure and swine manure were processed in feed resource to obtain regenerated feed by solid phase en‐zyme technology .The pretreatment process of manure and the type and addition amount of enzyme were optimized .It was indi‐cated that crude protein content of poultry manure feed and swine manure feed were 23 .80% and 15 .15% ,respectively ,and acid soluble protein content were 14 .80% and 7 .94% ,respectively .The content of crude protein and acid soluble protein by the solid phase enzyme hydrolysis were increased by 19 .16% and 18 .82% than that of drying group;the ratio of the added value of the acid soluble protein content and the real protein were 29 .06% and 28 .22% ,respectively ;the total number of bacteria in regen‐eration feed are less than 1 000 CFU/g ,and the content of vomitoxin reduced by 34 .8% on average .%利用固相酶解技术分别对鸡粪、猪粪进行饲料化处理，以获得再生饲料。通过对粪便前处理工艺、酶的种类及添加量等参数进行优化，获得再生饲料生产的最优工艺。产品检测结果为，鸡粪、猪粪再生饲料中粗蛋白质质量分数分别为23．80％和15．15％，酸溶蛋白质量分数分别为14．80％和7．94％，经固相酶解处理后酸溶蛋白与粗蛋白质的比值较直接烘干组提升18．82％、19．16％；处理后酸溶蛋白含量增加值与真蛋白的比值分别为29．06％、28．22％。再生饲料中细菌总数≤1000 C F U／g ，呕吐毒素含量平均下降34．8％。
