Preparation method of livestock and poultry acidification and glycolysis feed

Abstract

The invention relates to a preparation method of a livestock and poultry acidification and glycolysis feed. The method comprises the following steps: crushing a starch-containing product, mashing the crushed starch-containing product, carrying out enzymatic hydrolysis to prepare a residue-containing saccharification liquid or carrying out solid-liquid separation to obtain a residue-free saccharification liquid; inoculating the residue-containing saccharification liquid to citric acid producing strains, and carrying out solid-liquid separation to obtain acid residues and a citric acid fermentation liquid; inoculating the residue-free saccharification liquid to lactic acid production strains, fermenting the inoculated saccharification liquid, and acidifying the fermented saccharification liquid to prepare a lactic acid fermentation liquid; concentrating one or more of the lactic acid fermentation liquid and the citric acid fermentation liquid to prepare an organic acid concentrate liquid; mixing one or more of sugar residues and acid residues with a feed raw material, a composite strain liquid and a compound enzyme, and carrying out enzymatic hydrolysis fermentation to prepare glycolysis residue meal; and mixing the organic acid concentrate liquid and the glycolysis residue meal with one or more of feeding inorganic acids, organic acid salts, carbohydrates and grease to prepare the livestock and poultry acidification and glycolysis feed. The livestock and poultry acidification and glycolysis feed prepared in the invention is rich in organic acids, small peptides, oligosaccharides, probiotics and other nutrients, and has the characteristics of diarrhea resistance, good palatability and easy digestion.

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 acidification and fermentation feed for livestock and poultry. Background technique [0002] In recent years, food safety and environmental pollution have been widely concerned by governments at all levels in various countries, which are related to the health and life safety of the people. The safety of animal products requires that the feed has no drug residues, and the environmental protection requires that the feed has low pollution. In the past, we talked about "effective and safe" feed, but now the Ministry of Agriculture has repeatedly emphasized "safe, effective and low pollution". As we all know, since the advent of antibiotics, their use in livestock and poultry to prevent diseases and stimulate growth has indeed received good results. However, with the passage of time, the defects of antibiotics ...

AI Technical Summary

Problems solved by technology

However, the preparation method of this patent has the following defects: 1. It does not contain functional active nutrients such as probiotics, oligosaccharides, and small peptides, and has poor anti-diarrhea effect, which is poor in replacing or reducing feed antibiotics; 2. It hardly contains protein , crude fiber, crude fat, vitamins and mineral elements and other conventional nutrients, a small amount of conventional nutrients such as protein, crude fiber, crude fat, vitamins and mineral elements are all from the fruit, not from the enzymatic hydrolysis of sugar residue and acid residue Fermentation; 3. A large amount of non-nutritive silica is added as a carrier, which seriously affects the palatability and feed intake of livestock and poultry; 4. It is only an additive with a small amount added, which is inconvenient to use in small farms ; 5. The sugar residue and acid residue produced in the fermentation process of organic acid production have not been effectively treated, resulting in serious pollution
