不同湿度条件对肉鸡浓缩料中霉菌污染的影响

研究了室温条件下不同湿度(RH)贮存饲料的霉菌污染情况,在湿度条件分别为65%RH、75%RH、85%RH,利用国标检测法进行霉菌总数、产毒菌种类及毒素含量分析。结果表明,在20℃、65%RH条件下,饲料存放到第17天前就应该采取防霉措施。在75%RH条件下,存放到第10天前就应该采取防霉措施。在85%RH条件下,在生产饲料的时候就应该采取防霉措施。

Impact of different relative humidity on mould contamination in broiler concentrated feeds

At room temperature, the influence of relative humidity on the mould contamination during the broiler concentrated feeds imbursement was studied. When the levels of relative humidity were 65%, 75% and 85%, through national standard test method, the mould sum, the kinds of toadstool and toxin content were analyzed. The results show that, under the conditions of 65%RH and 20 ℃, the anti-mildew measures should be adopted before the 17th day, and when the relative humidity is 75%, the anti-mildew measures should be adopted before the 10th day. When the relative humidity reaches 85%, the anti-mildew measures should be taken during the produce of the broiler concentrated feeds.
