摘要
利用米曲霉和白地霉接入鲜鸡粪与麸皮等混合料中进行固态发酵 ,并在发酵过程中添加氮源 (尿素 ) ,使得鸡粪饲料粗蛋白与氨基氮含量都较高 ,分别为 2 0 .70 %、19.74 % ,培养物中的氨基氮由发酵前的 5 6 .89%提高到发酵后的 95 .36 % ,饲料适口性较好 ,可替代部分配合饲料 ,喂猪试验表明添加4 0 %鸡粪饲料后 ,猪日增重比单喂配合饲料增加 10 .83%。
Protein feed are produced from the mixtures of chicken manure and wheat bran with the aspergillus oryzae and geotrichum candidum by solid state fermentation., at the same time, nitrogen source (urea) was added to the culture in the course of the fermentation.The contents of protein and amino nitrogen in the chicken manure feed reach 20.70% and 19.74% and the amino nitrogen in culture change from 56.89% to 95.36%. The feed is very tasty and can replace partial formula feed. The result of feeding pig showed that the average daily gain is increased by 10.83% compared with the control group.
