Preparation method of feeding ferrous lactate

Abstract

The invention relates to a preparation method of feeding ferrous lactate, which comprises the steps of: crushing starch substances, adding water and performing slurry mixing, adding a liquefying enzyme and a saccharifying enzyme, performing enzymolysis liquefying and saccharifying, performing solid-liquid separation to obtain a sugar residue wet base and non-residue saccharifying liquid, inoculating lactic acid producing strains into the non-residue saccharifying liquid, fed-batching calcium hydroxide or calcium carbonate, performing a fermentation reaction, and performing solid-liquid separation to obtain a strain acid residue wet base and calcium lactate weak liquid; adding ferrous sulfate or ferric chloride into the calcium lactate weak liquid, enabling a reaction and performing solid-liquid separation to obtain calcium sulfate and ferrous lactate weak liquid; concentrating the ferrous lactate weak liquid to obtain ferrous lactate concentrated liquid; mixing one or two of the sugar residue wet base, the strain acid residue wet base and feed raw materials and one or two of clean water, stone powder, composite strain liquid and composite enzymes, and performing enzymolysis and fermentation to obtain a glycolysis feed wet base; and mixing and drying the glycolysis feed wet base and the ferrous lactate concentrated liquid to obtain the feeding ferrous lactate. The product provided by the invention is rich in ferrous lactate, lactic acid and ferrous lactate, and has the characteristics of rapid absorption, good iron supply effect, high palatability and the like.

Description

technical field [0001] The invention belongs to the technical fields of feed, enzyme preparations and microorganisms, and in particular relates to a preparation method of ferrous lactate for feeding. Background technique [0002] China is a country with a large population and a large breeding industry. 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. Among them, 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, 90 million tons of poultry feed, 53 million tons of ...
