不同菌种对香蒲发酵饲料的影响

Effect of Different Strains on Typha Fermented Feed

以衡水湖香蒲为主要发酵原料,分别加入4种单菌、混合菌、不接菌或自然发酵,利用微生物将其转化为利于牲畜消化吸收的饲料,研究不同菌种和接种方式对香蒲发酵情况的影响。试验结果表明:随时间增加,粗蛋白、粗纤维含量变化增加显著;灭菌发酵优于自然发酵;混菌发酵优于单菌;各单菌比较,黑曲霉效果最强。

Typha in Hengshui lake taken as the main fermentation material,four kinds of single bacteria,mixed bacteria,non-inoculated bacteria or natural fermentation were added respectively,and the microorganisms were used to convert them into feed which was conducive to digestion and absorption of livestock,the effects of different strains and inoculation methods on the fermentation of cattail were studied.The experimental resulted show that:With the increase of time,the content of crude protein and crude fiber increased significantly;Sterilization fermentation is superior to natural fermentation.Mixed fermentation was superior to single fermentation;Comparison of single bacteria,Aspergillus niger was the most effective bacteria.
