The invention discloses novel biological protein feed and a production method thereof. The novel biological protein feed is prepared from the following materials in percentage by weight: (1.0%-3% of)bacterial liquid, (40%-60% of) bean meals and (40%-60% of) water. The novel biological protein feed is characterized in that fine strains is used to ferment the bean meals so as to produce the biological protein feed, thereby reducing the water content, shortening the fermentation time, reducing the production cost, being simple and easy to operate and having high practicality; the pH value of theproduced biological protein feed restrains the growth of harmful intestinal tract bacteria; the strain number of the fermented biological protein feed reaches 10<8> so as to regulate the balance of the gastrointestinal tract bacterial flora of livestock and poultries; the stress reaction ability of the livestock and poultries is enhanced by enhancing the oxidation resisting ability of livestock and poultry organisms; and the protein metabolism efficiency is enhanced and the weight increment and feed utility ratio are enhanced by improving the blood biochemical indexes of the organisms.
