摘　　要：雏鸡鸡粪中还剩余有丰富的营养物质,作者用乳酸菌、酵母菌、嗜热异养氨氧化细菌和嗜热侧孢霉菌组成混合微生物菌剂,将雏鸡鸡粪与由玉米粉、麸皮和豆粕组成的混合辅料混合发酵48 h。结果表明,与发酵前相比,利用微生物发酵可很大程度上改善鸡粪的感观特征,提高其适口性。经过发酵后,大肠杆菌含量在100 CFU/g以下,沙门氏菌和志贺氏菌全部被杀灭;饲料中总氨基酸质量分数达到12.89%,真蛋白质量分数高达18.34%,均比发酵前有明显提高,而且其中粗纤维降低了21.97%,明显低于发酵前。将发酵好的鸡粪饲料按25%添加到日粮中饲喂27 d,对鸡仔的生长没有不良影响,实现了雏鸡鸡粪的资源化利用。As chicken manure was still rich in nutrient,in this research,it was fermented by lactic acid bacteria,yeast,thermophilic heterotrophic ammonia-oxidizing and Sporotrichum thermophile as microbial agents and the mixture of corn flour,wheat bran and soybean meal as auxiliary materials.After fermentation for 48 hours,the result indicated that the sensory properties and palatability of chicken manure improved greatly.Furthermore,the content of E.coli reduced to less than 100 CFU/g,all the Salmonella and Shigella in chicken manure were killed.The content of amino acid and true protein reached to 12.89%and 18.34%respectively,which were higher than pre-fermentation,and the crude fiber was decreased by 21.97%.After feeding chicken with the fermented chicken manure for 27 days,results showed that adding 25%of the fermented chicken manure in the daily food did not affect the growth of chicken.This was a new way for utilization of chicken manure.
