Embodiment 1

[0028] The specific techniques or conditions not indicated in this embodiment were all carried out according to the techniques or conditions described in the literature in this field or according to the product instructions. Reagents or instruments whose manufacturers are not indicated are all commercially available conventional products. According to the US NRC (2012) nutritional requirements of pigs, a full-price diet was configured for the experiment.

[0029] A total of 180 Du Sanyuan pigs with similar ages, weights, and health status were selected and randomly divided into 6 treatment groups (5 replicates in each treatment group, 6 pigs in each replicate), respectively as control group and pigs. 5 test groups (test group 1, test group 2, test group 3, test group 4, test group 5), each added to the basal diet (referring to the US NRC (2012) pig nutritional requirements). The composition of the basal diet is shown in Table 1, and the composition of feed additives in each t...

Embodiment 2

[0045] A feed additive for improving intestinal health, comprising the following components and contents by weight: 0.2 part of milk thistle extract, 0.6 part of perilla extract, 0.5 part of Boluohui extract, 1 part of Atractylodes polysaccharide, tannic acid 3 parts and 1 part of Lactobacillus plantarum powder.

[0046] Among them, in the milk thistle extract, the mass percentage of silymarin is 78%; in the perilla extract, the mass percentage of sclareolide is 99%; The percentage content is 55%; in the Lactobacillus plantarum powder, the effective live bacteria content is ≥1×10 11 CFU / g.

[0047] The preparation method of the feed additive comprises the following steps:

[0048] 1) Pass milk thistle extract, Perilla extract, Boluohui extract and Atractylodes macrocephala polysaccharide through a 60-80 mesh sieve, mix, and then sieve again;

[0049] 2) adding tannic acid and Lactobacillus plantarum powder, mixing evenly, granulating, and drying to obtain a feed additive. ...

Embodiment 3

[0052] A feed additive for improving intestinal health, comprising the following components and contents by weight: 1 part of milk thistle extract, 0.2 part of perilla extract, 1 part of Boluohui extract, 0.2 part of Atractylodes polysaccharide, tannic acid 6 parts and 0.5 part of Lactobacillus plantarum powder.

[0053] Among them, in the milk thistle extract, the mass percentage of silymarin is 90%; in the perilla extract, the mass percentage of sclareolide is 96%; The percentage content is 75%; in the Lactobacillus plantarum powder, the effective live bacteria content is ≥1×10 11 CFU / g.

[0054] The preparation method of the feed additive comprises the following steps:

[0055] 1) Pass milk thistle extract, Perilla extract, Boluohui extract and Atractylodes macrocephala polysaccharide through a 60-80 mesh sieve, mix, and then sieve again;

[0056] 2) adding tannic acid and Lactobacillus plantarum powder, mixing evenly, granulating, and drying to obtain a feed additive. ...

Abstract

The invention relates to a feed additive for improving health of intestinal tracts and a preparation method and application of the feed additive. The feed additive comprises a silybum marianum extract, a purple perilla extract, a macleaya cordata extract, bighead atractylodes rhizome polysaccharide, tannic acid and lactobacillus plantarum powder. The preparation method comprises the following steps of during preparation, firstly, separately screening the silybum marianum extract, the purple perilla extract, the macleaya cordata extract and the bighead atractylodes rhizome polysaccharide, thenperforming mixing, adding the tannic acid and the lactobacillus plantarum powder, after uniform mixing, performing granulation and performing drying. During application, the feed additive is added toa basic ration, wherein the addition proportion of the feed additive to the basic ratio is 0.5-2wt%. Compared with the prior art, the feed additive provided by the invention can promote growth and development of animals, and the diarrhoea rate and the attack rate are reduced; and besides, damage of harmful bacteria to the intestinal tracts can also be reduced, the growth of beneficial bacteria inthe intestinal tracts is promoted, the intestinal flora can be maintained balanced, the immune function can be reinforced, and the health of the intestinal tracts can be improved.

Description

technical field [0001] The invention belongs to the technical field of feed additives, and relates to a feed additive for improving intestinal health, a preparation method and application thereof. Background technique [0002] Under intensive and large-scale breeding conditions, animals are stressed due to stocking density, immunization, virus infection, fright, etc., and they are prone to physiological problems such as diarrhea and intestinal flora imbalance, making nutrients unable to be digested and absorbed, and serious It affects the growth and development of animals, resulting in reduced production performance and reduced meat quality, causing huge losses to the production efficiency of the farm. Although the use of antibiotics can alleviate the above situation, it will cause the disorder of animal intestinal flora, enhance bacterial resistance, produce toxic and side effects, and seriously affect the quality and food safety of animal products, indirectly endanger huma...
