湿态发酵蛋白饲料是玉米经酵母发酵、提取酒精后,又经益生菌发酵、密封包装的产物,其可溶性好、易消化、易吸收、蛋白质含量高。通过对肉牛进行饲喂试验可知,肉牛食用8kg该饲料,平均每头牛日增重1.81kg,比对照组高0.26kg;平均屠宰率为57.1%,比对照组高3.8%;平均售价为21.35元/kg,比对照组高1.52元/kg;平均每日比对照组多收益6.1元。试验结果表明,肉牛饲喂湿态发酵蛋白饲料增重效果好、屠宰率高,经济效益显著提高。%Wet fermented protein feeds are the products of maize which are treated by yeast fermentation, alcohol extraction, probiotics fermentation and sealing packaging. Through fattening experiment of beef cattle, results showed that after one beef cattle was fed with 8 kg wet fermented protein feed, beef cattle growth reached 1.81 kg per beef cattle which was 0.26 kg more than control; the average dressing percentage was 57.1% which was 3.8% more than control; the average selling price was 21.35 yuardkg which was 1.52 yuardkg more than control; there was 6.1 yuardd of income more than control. It was concluded that after beef cattle were fed with wet fermented protein feeds, there were good beef cattle growth and high dressing percentage, and economic benefit was improved significantly.
