Preparation method of fish meal small peptide feed

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, ...
