摘要
为检查鸡粪作为再生饲料的安全性,对发酵前和经两种方法发酵处理后的鸡粪样品进行了沙门氏菌Salmonella和大肠埃希氏菌Escherichiacoli检测。结果表明,发酵前新鲜鸡粪样品可检出沙门氏菌,大肠埃希氏菌数为1 39×108个·g-1,经直接发酵和复合微生物发酵处理的鸡粪样品均未检出沙门氏菌,大肠埃希氏菌数分别减少至2 3×106个·g-1和2 6×104个·g-1,与发酵前样品均存在极显著差异(P<0 01);复合微生物发酵处理后的大肠埃希氏菌数明显少于直接发酵样品。
To investigate the safety of chicken's excrement as reused forage,the numbers of E.coli and Salmonella in fresh chicken's excrement,chicken's excrement samples by direct and complex microorganism fermentation were surveyed.The results showed that no Salmonella in fermented samples was detected,and the number of E.coli decreased from 1.39×10~8·g^(-1) to 2.3×10~6·g^(-1) and 2.6×10~4·g^(-1) after fermentation.The difference was very significant (P<0.01) as compared with the samples before fermentation.The numbers of E.coli were much less in samples fermented by complex muroorganism than samples by direct fermentation.
