Fermented dietary fiber feed raw material and preparation method thereof

Abstract

The invention belongs to the technical field of feeds, and particularly relates to a fermented dietary fiber feed raw material and a preparation method thereof. The microbial agent comprises the following components in parts by weight: 55-60 parts of a fermentation substrate and 40-45 parts of a bacterial liquid, wherein the fermentation substrate is a plant raw material containing crude fibers; bacteria liquid, wherein the viable count concentration of bacillus subtilis is 1-3 * 10 <8> CFU / ml, the viable count concentration of saccharomycetes is 1-3 * 10 <8> CFU / ml, the viable count concentration of lactobacillus delbrueckii is 1.5-4 * 10 <8> CFU / ml, and the viable count concentration of lactobacillus plantarum is 1.5-4 * 10 <8> CFU / ml. The mixed strain is added to ferment the crude fiberraw material, so that the content of resistant components in the material can be remarkably reduced, and the protein content of the bran is increased while the content of vomitoxin in the bran is reduced; moreover, the pH value of the material is reduced, the fermentation metabolite of the strain and the viable count of probiotics are increased, the eating desire of animals is effectively promoted, the palatability is greatly improved, the intestinal health of the animals is favorably ensured, and the effect of the fermented dietary fiber feed raw material is stable.

Description

technical field [0001] The invention belongs to the technical field of feed, and specifically refers to a fermented dietary fiber feed material and a preparation method thereof. Background technique [0002] Dietary fiber is a substance that cannot be digested by the body. It can neither be absorbed by the small intestine nor produce energy, but it has health significance. Dietary fiber is a carbohydrate polymer that exists naturally in plants or synthesized by extraction, and has a degree of polymerization DP ≥ 3. It can be divided into two categories-soluble dietary fiber and insoluble dietary fiber. Soluble dietary fiber comes from carrots, oats, citrus, lemons, apples, peas, cabbage and other fruit and vegetable foods, including hydrocolloid substances such as pectin and some hemicelluloses, located in plant cell fluid and intercellular substance; insoluble dietary fiber A large amount of fiber exists in cereal grains, such as oatmeal, brown rice, wheat bran, beans, fru...

AI Technical Summary

Problems solved by technology

Dietary fiber feed raw materials are of great significance to animal intestinal health in animal husbandry. In recent years, research on dietary fiber raw materials such as wheat bran and soybean hulls has attracted more and more attention. Among them, processing fiber raw materials by fermentation can improve Feed nutrients, reducing the content of anti-nutritional factors, on the other hand, can increase the number of probiotics and improve their flavor and palatability, but the existing fermentation methods have the defects of unstable effects or difficult to achieve the desired purpose
