Abstract

The invention belongs to the technical field of fermentation of feeds, enzymic preparations and microorganism, in particular to a preparation method of a soluble easily-digested feed for young livestock and poultry. Impurity removal and smashing of corn, wheat and broken rice are performed, water is added into cereals to manufacture pulp, and a-amylase and glucoamylase are added to prepare enzymatic hydrolysate. Filtrate, plasma protein, lactose and the like are mixed to prepare dextrin priming. Filter residues, soya bean meal and the water are evenly mixed, then fungi are inoculated to perform anaerobic fermentation and enzymolysis, and small-peptide protein slurry is prepared through superfine grinding and defibrination. A total-nutrition solution is prepared through mixing, and emulsified liquid is prepared through filter pressing and homogeneity of a high-pressure homogenizer. The emulsified liquid is directly packed into a paste or liquid feed, or is manufactured into a powder feed through absorption of extruded corns and drying of a tube bundle dryer, or is manufactured into a small-pellet feed through the drying of a spray dryer after tempering is performed by adding the water. The feed is rich in short-chain dextrin, glucose, oligosaccharide, small peptide, lactic acid and probiotics and has the advantages of being balanced in amino acid, high in nutrition, easy to digest, good in palatability, low in antinutritional factor content and the like.

Description

technical field [0001] The invention belongs to the technical field of feed, enzyme preparation and microbial fermentation, and in particular relates to a preparation method of soluble and easily digestible feed for young livestock and poultry. Background technique [0002] China is a country with a large population and a large breeding industry.
