Abstract

The invention relates to a preparation method of an acidification calcium salt zymohydrolysis feed for livestock and poultry, and belongs to the technical field of feeds. The preparation method comprises the following steps of performing pulp-mixing on starch-containing substances, performing enzymolysis, performing saccharification, performing inoculating with lactic-acid-generating strains for fermentation, performing fed batch of calcium oxide for fermentation, and after performing separation and concentration, obtaining a thalli acid sludge wet basis and a calcium lactate concentrated solution containing lactic acid; after performing pulp-mixing on starch-containing substances, performing enzymolysis, performing saccharification, performing inoculating with citric-acid-generating strains for fermentation, and after performing separation and concentration, obtaining a citric acid sludge wet basis and a citric acid concentrated solution; mixing one or more of the sugar sludge wet basis, the thalli acid sludge wet basis and the citric acid sludge wet basis with feed raw materials, clean water, compound bacteria and complex enzymes, and then performing zymohydrolysis so as to obtain a zymohydrolysis sludge meal wet basis; and mixing the calcium lactate concentrated solution with the citric acid concentrated solution and the zymohydrolysis sludge meal wet basis to prepare the acidification calcium salt zymohydrolysis feed for livestock and poultry. The prepared feed disclosed by the invention is rich in nutrient components of citric acid, calcium lactate, lactic acid, smallpeptides, oligosaccharide and the like, and has the characteristics of being high in calcium absorption rate, resistant to diarrhoea, good in palatability and the like.

Description

technical field [0001] The invention belongs to the technical field of feed processing, and in particular relates to a preparation method of acidified calcium salt fermented feed for livestock and poultry. Background technique [0002] China is a big country in aquaculture. In 2015, the output value of animal husbandry reached 3.2 trillion yuan, and the output of meat, poultry eggs, milk and aquatic products reached 84.54 million tons, 28 million tons, 38 million tons and 55 million tons respectively. Along with the development of aquaculture, the feed industry has developed at an astonishing speed. According to statistics from the Ministry of Agriculture, the national commercial feed production reached 218 million tons in 2015, including 179 million tons of full-price feed, 21.51 million tons of concentrated feed, 6.4 million tons of premixed feed, including 89.74 million tons of pig feed and 89.74 million tons of poultry feed. 90 million tons, 53 million tons of aquatic ...
