摘要
发酵活干菌处理秸秆比未处理秸秆 CP含量提高 12 .4 %。60 d饲养试验结果表明 ,秸秆经发酵活干菌处理后显著地改善了适口性 ,试验组牛的日均采食量和采食率分别比对照组牛提高 30 .9%和 2 5.1% ,日增重提高 73.56% ,同期增加经济效益 118.5元 /头 ,具有较好的推广价值。
The CP content of straw treated by living dry bacteria for fermentation increased by 12.4% compared with that of non treated straw. A 60 d feeding experiment result showed that the palatability of straw was significantly improved after treated by living dry bacteria for fermentation. The preparation increased daily intake(30.9%), intake rate (25.1%) , daily gain(73.56%) compared with CK group. And the economic benefit increased by 118.5 yuan per cattle.
