Abstract

The invention discloses a feed additive for improving the immunity of weaned piglets, and a preparation method thereof. The feed additive is prepared from a component A and a component B through a solid state fermentation process; during fermentation, the mass ratio of the component A to the component B is 1:15 to 1:30, wherein the component A is a mixed strain comprising at least two probiotic seed solutions; the colony count of each probiotic is greater than 108 CFU / ml; and the component B at least comprises one or a mixture of two of codonopsis pilosula and astragalus membranaceus. The feedadditive for improving the immunity of the weaned piglets provided by the invention is a Chinese herbal medicine additive fermented by probiotics; release of immunologic active substance polysaccharide and synthesis of small peptides can be promoted; the content of polysaccharide before and after fermentation is 2.35% and 2.98% respectively; the content of the small peptides is improved to 6.42%from 4.97%; the immunity and disease resistance of organisms are effectively improved; and the feed additive is an ideal antibiotic substitute product after the feed is completely prohibited.

Description

technical field

[0001] The invention relates to a feed additive, in particular to a feed additive for improving immunity of weaned piglets. The invention also relates to a preparation method of the feed additive. Background technique

[0002] Due to changes in the environment, stress and dietary form, piglets are prone to indigestion at weaning, resulting in diarrhea, slow growth, and even death. According to relevant data reports, in my country's small and medium-scale pig farms, the diarrhea rate of piglets during weaning is as high as 50% to 60%, and the mortality rate is as high as 15% to 20%. Diarrhea in weaned piglets has caused huge economic losses to pig production.

[0003] In the past, it was common practice to add antibiotics or chemically synthesized drugs to feed to prevent or alleviate diarrhea in weaned piglets, but these drugs would cause pathogenic microorganisms to develop resistance and lead to antibiotic residues in animal products, which brought huge hi...

Examples

Embodiment 1

[0025] Component B was prepared with Codonopsis pilosula and Radix Astragali as traditional Chinese medicine additives.

[0026] Enterococcus faecium and Bacillus licheniformis are used as component A of probiotic fermentation strains.

[0027] In this embodiment, the feed additive probiotic fermentation strain ratio is Enterococcus faecium: Bacillus licheniformis=1:1, and the mass ratio of Chinese medicine matrix for invigorating the middle and nourishing Qi is Codonopsis: Astragalus=1:1, according to 5% of the mass of Chinese medicine matrix. % Add strains for solid-state fermentation to prepare a mixed non-antibiotic Chinese herbal medicine fermented feed additive that improves the immunity of weaned piglets.

[0028] The preparation method comprises the steps of:

[0029] 1) Preparation of traditional Chinese medicine matrix (component B): select authentic Chinese medicinal materials Codonopsis pilosula and Astragalus membranaceus, after mixing according to the ratio of C...
