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、密封包装的产品。因其可溶性好、易消化吸收、所含的蛋白质量多质优,因此,用于肉牛育肥时,肉牛生长速度较快。通过对饲喂湿态发酵蛋白饲料育肥牛（15头,来自2个饲养场）的屠宰率与饲喂常规饲料育肥牛的屠宰率（425头,来自24个饲养场）进行统计对比可知,肉牛的屠宰率与屠宰时的体重成高度正相关（R2=0.9528）,并且全程饲喂湿态发酵蛋白饲料育肥牛的屠宰率比饲喂常规饲料育肥牛的屠宰率平均高3.65个百分点,这样1头牛将多收入640元。因此,饲喂湿态发酵蛋白饲料会使肉牛育肥经济效益显著提高。

Wet fermented protein feed of maize product with sealed package that was fermented by probiotic bacteria after yeast fermentation and alcohol extraction.Because it had good solubility,strong digestion and absorption abilities,rich and high-quality protein,the growth speed of beef cattle was fast when it was used in the fattening of beef cattle.The slaughter rate of 15 fattening cattle from 2 breeding farms that was fed with wet fermented protein feed was compared with that of 425 fattening cattle from 24 breeding farms that was mot fed with wet fermented protein feed.It was shown that the slaughter rate of beef cattle showed highly positive correlation with the slaughter weight(R2=0.952 8).And the slaughter rate of fattening cattle that was fed with wet fermented protein feed in the whole test period was 3.65 percentage points higher than that of fattening cattle that was fed with conventional feed,and thus the income for each cattle increased 640 yuan.Therefore,the economic benefit of the beef cattle's fattening was significantly enhanced by feeding with wet fermented protein feed.
