Embodiment 1

[0022] Mix 100kg of commercially available poor-quality fish meal with strong smell, 10kg of molasses, 5kg of brown sugar, and 0.2kg of microbial protease (300U / g substrate wet base), then add 180kg of clean water, 30kg of lactic acid bacteria and 20kg of yeast , Was prepared into a liquid fermentation medium, heated to 38℃-42℃, after a first liquid fermentation enzymatic hydrolysis for 60 hours, 60kg corn meal and 250kg alfalfa grass powder were added, and the second solid fermentation enzymatic hydrolysis under the condition of 32℃-38℃ After 72 hours, the fish meal small peptide feed (wet basis) with the odor eliminated and the fishy sour taste is prepared, or the fish meal small peptide feed (dry basis) is prepared by drying.

[0023] The nutrient content in the fish meal small peptide feed (wet basis) prepared in Example 1 is shown in the following table:

[0024] Item

Embodiment 2

[0026] After mixing 100kg of commercially available poor-quality fish meal with strong smell, 20kg molasses, 10kg glucose and 0.2kg microbial protease (300U / g substrate wet base), add 250kg clean water, 25kg lactic acid bacteria seed liquid and 15kg yeast seed liquid , Prepared into a liquid fermentation medium, heated to 38℃-42℃, after 72 hours of primary liquid fermentation, 50kg corn meal and 200kg alfalfa powder were added, and the second solid fermentation was carried out at 32℃-38℃. After 96h, the fish meal small peptide feed (wet basis) with the odor eliminated and the fishy sour taste is prepared, or the fish meal small peptide feed (dry basis) is prepared by drying.

Embodiment 3

[0028] After mixing 500kg of commercially available poor-quality fish meal with strong smell, 80kg molasses, 30kg glucose and 1.2kg of microbial protease (350U / g substrate wet base), add 1500kg clean water, 100kg lactic acid bacteria seed liquid and 60kg yeast seed liquid , Prepared into a liquid fermentation medium, heated to 38 ℃-42 ℃ for a liquid fermentation enzymatic hydrolysis for 48 hours, 300kg corn meal and 800kg alfalfa grass powder were added, and the second solid fermentation enzymatic hydrolysis at 32 ℃-38 ℃ After 120h, the fish meal small peptide feed (wet basis) with the odor eliminated and the fishy sour taste is prepared, or the fish meal small peptide feed (dry basis) is prepared by drying.

Abstract

The invention belongs to the technical field of fermentation of feeds, enzymic preparations and microorganisms and in particular relates to a preparation method of a fish meal small peptide feed. The preparation method of the fish meal small peptide feed comprises the following steps: mixing commercially-available poor-quality fish meal, molasses, brown sugar or glucose, water, microorganism protease, lactic acid bacteria strain liquid and saccharomycetes strain liquid to prepare a liquid fermentation culture medium, carrying out primary liquid fermentation and enzymolysis for 2-120 hours at the temperature being 20-70 DEG C to prepare fish meal small peptide liquid; mixing the fish meal small peptide liquid, corn flour and alfalfa powder to prepare a solid fermentation culture medium, carrying out secondary solid fermentation and enzymolysis for 6-360 hours at the temperature being 10-50 DEG C to prepare the fish meal small peptide feed. The prepared fish meal small peptide feed is capable of removing anti-nutritional factors, killing pathogenic microorganisms, producing abundant small peptides, lactic acid, yeast protein and probiotics, removing odor, presenting fishy sourness, improving the feed intake of livestock and poultry, promoting growth of piglets and improving milk yield of milking sows.

Description

Technical field [0001] The invention belongs to the technical field of feed, enzyme preparation and microbial fermentation, and specifically relates to a method for preparing fish meal small peptide feed. Background technique [0002] China is a populous country and the world's largest pig raising country. In 2011, the output value of China's animal husbandry reached 2.2 trillion yuan, and 646 million live pigs were slaughtered, including 48 million sows and 50.53 million tons of pork. According to statistics from the Ministry of Agriculture, my country’s total commercial feed output will reach 180 million tons in 2011, including 149 million tons of compound feed; 25 million tons of concentrated feed; 6.05 million tons of additive premix feed, of which more than 5 million tons of sow feed. In 2011, the total output value of the national feed industry was 541 billion yuan. It is estimated that by 2015, the national compound feed production will reach more than 200 million tons, ...
