Abstract: 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 cow, results showed that after one cow was fed with 4 kg wet fermented protein feed, milk yield was improved by 2.18 kg, and income was increased by 2.03 yuan/d per cow, which suggested good yield-increasing effect and significant economic benefit. Besides, it was found that adding 4 kg wet fermented protein feed every day had no significant effect on milk composition.
