试验采用微贮发酵技术对棉花秸秆进行发酵处理,将体重相近的育肥牛8头随机分为两组,试验组在日粮中添加微贮棉杆,对照组在日粮中添加粉碎的棉杆,同时添加营养添砖自由采食,研究微贮棉秆饲喂肉牛增重效果。结果表明,饲粮中添加微贮棉杆组育肥牛采食量增加350 g.d^-1.头^-1,平均日增重多118 g.头^-1,试验组与对照组相比差异显著（P〈0.05）。试验结果表明,棉花秸秆通过用微贮发酵处理,饲喂育肥牛可增加采食量和达到增重效果,经济效益明显。因此,可以考虑在生产中较大范围地使用微贮棉秆饲喂肉牛。

A single factor experiment design was carried out and 8 finished cattles were chosen,and there were two treatments in the trial（microbial-treated cotton stalk 350 g·cattle-1·d-1 and control only including untreated cotton stalk）.The purpose of this study was finding the best combination of microbial-treated cotton stalk and multinutrient blocks in feeding finished cattles.The results showed that the diets intake and average daily gain of cattles fed microbial-treated cotton stalk were higher than cattles fed control diet significantly（P0.05）.The average daily gain of cattles fed microbial-treated cotton stalk was 118 g higher than cattles fed control diet.It suggested that microbial-treated cotton stalk could rise intake and average daily gain of finished cattle and increase economic benefit.As a result,microbial-treated cotton stalk should be popularized in finished cattle production.
