Abstract

Rice straw's poor palatability and low nutrition limit its utilization as livestock feed, resulting in low intake rates. To address this, three fermentation treatments (compound bacteria, compound bacteria + enzymes, lactic acid bacteria) were tested over 25, 45, and 65 days, analyzing crude fiber, soluble sugar, and protein to evaluate quality. Results showed compound bacteria + enzymes performed best at 65 days: crude fiber reduced to 34.83%, crude protein increased to 9.45%, and soluble sugar reached 1.89%. Feeding trials with Simmental cattle revealed a 93% intake rate for fermented straw—65% higher than unfermented. This study establishes a microbial degradation technology for rice straw, identifies optimal starters, and forms a feed production process, laying a foundation for enhanced rice straw utilization as livestock feed.

水稻秸秆适口性差、营养价值低，使其作为畜禽饲料的利用率受限，导致采食率偏低。针对这一问题，本研究采用三种发酵处理方式（复合菌、复合菌 + 酶、乳酸菌），分别发酵 25 天、45 天和 65 天，并通过分析粗纤维、可溶性糖和蛋白质含量来评估饲料品质。结果显示，复合菌 + 酶处理在 65 天时效果最佳：粗纤维含量降至 34.83%，粗蛋白含量提升至 9.45%，可溶性糖含量达 1.89%。对西门塔尔牛的饲喂试验表明，发酵秸秆的采食率为 93%，较未发酵秸秆提高 65%。本研究建立了水稻秸秆的微生物降解技术，筛选出了适宜的发酵剂，形成了秸秆饲料生产工艺，为提升水稻秸秆作为畜禽饲料的利用率奠定了基础。
