Embodiment 1

[0022] A composite fiber additive for improving pork quality, prepared from the following raw materials in weight percentage: 19% of oat bran, 16% of wheat bran, 8% of microcrystalline cellulose, 5% of beet pulp, 5.5% of pea fiber, and 5% of lentinan %, fructooligosaccharide 3%, inulin 3%, konjac gum 3.5%, sodium alginate 1.3%, corn starch 30.7%.

[0023] The preparation method is:

[0024] 1) Pulverize oat bran, wheat bran and sugar beet pulp respectively, pass through 80-mesh sieve and select for later use;

[0025] 2) Mix the pulverized oat bran, wheat bran, and beet pulp with microcrystalline cellulose, pea fiber, lentinan, fructooligosaccharide, inulin, konjac gum, and sodium alginate in proportion, and then add Mix the cornstarch evenly.

Embodiment 2

[0027] A composite fiber additive for improving pork quality, prepared from the following raw materials in weight percentage: 11% of oat bran, 9% of wheat bran, 6% of microcrystalline cellulose, 3% of beet pulp, 4% of pea fiber, and 3% of lentinan %, fructooligosaccharide 1%, inulin 2%, konjac gum 3%, sodium alginate 0.6%, corn starch 57.4%.

[0028] The preparation method is the same as in Example 1.

Embodiment 3

[0030] A composite fiber additive for improving pork quality, prepared from the following raw materials in weight percentage: 26% of oat bran, 20% of wheat bran, 10% of microcrystalline cellulose, 7% of beet pulp, 6% of pea fiber, and 7% of lentinan %, fructooligosaccharide 4%, inulin 5%, konjac gum 5%, sodium alginate 1.7%, corn starch 8.3%.

[0031] The preparation method is the same as in Example 1.

Abstract

The invention relates to the technical field of animal feeds, in particular to a composite fiber additive capable of improving the quality of pork as well as a preparation method and application of the composite fiber additive. The composite fiber additive is prepared from oat bran, wheat bran, microcrystalline cellulose, beet residues, pea fibers, lentinan, fructo-oligosaccharide, inulin, konjac gum, sodium alginate and corn starch. In the composite fiber additive disclosed by the invention, the total quantity of dietary fibers is 12-60%, so that indole and skatole in caeca and colons of pigs can be effectively reduced, and the level of the skatole in back fat is reduced; the growing performance and the meat quality of the pigs are obviously improved; the content of pathogenic bacteria such as escherichia coli, staphylococcus aureus and streptococcus pyogenes in chyme in colons and caeca of the pigs is reduced, the content of probiotics such as lactobacilli and faecalibacterium prausnitzii is increased, the growth and the health of the pigs are promoted, and besides, the composite fiber additive has the characteristic of being convenient to prepare and use.

Description

technical field [0001] The invention relates to the technical field of animal feed, in particular to a composite fiber additive for improving pork quality and its preparation method and application. Background technique [0002] In animal production, L-tryptophan contained in compound feed and endogenous protein will be degraded into indole and skatole under the action of anaerobic microorganisms in the hindgut (such as colon), and the apoptotic cells in the hindgut of animals will also May be used by microorganisms to produce skatole. Clostridium, Escherichia coli, Bacteroides polymorpha and other bacteria present in the pig colon metabolize tryptophan to produce indole acetic acid, which is also the main precursor for the production of skatole. After indole and skatole are produced in the large intestine, some of them are excreted through the feces, and the other part is absorbed into the blood circulation system through the intestinal cell wall, and then reaches the live...
