稻草发酵制备饲料工艺研究

Technology for Preparing Feed with fermented Rice Straw

稻草经盐酸预处理后 ,采用白腐真菌进行发酵制备饲料 ,对发酵工艺进行了优化 ,试验结果表明 ,当稻草发酵初始pH值为 7.0 ,接种量为 10 % ,发酵温度为 5 0℃时 ,发酵时间为 10d ,稻草可被降解 ,木质素含量下降 2 0 .4 8% ,蛋白质含量增加4 2 .83%。

Rice straw was pretreated with hydrochloric acid, and fermented with white-rot fungi for preparing animal feed. In view of optimizing the fermentation technology, the test results indicated that when the initial pH value of rice straw was 7.0, the inoculated amount was 10% and the fermentation was carried out under 50℃ for 10 days, the rice straw could be degraded with its contents of lignin and protein being decreased and increased by 20.48% and 42.83% respectively.
