Problems solved by technology

[0005] At present, the traditional Chinese medicine preparation feed additive commonly used in the breeding industry is prepared from the whole medicine of traditional Chinese medicine. The whole medicine of Chinese medicine needs to be digested by cows to absorb the effective drug ingredients. The drug utilization rate is low and the effect is slow; Therefore, it is often necessary to increase the dosage of feed additives for traditional Chinese medicine preparations, which not only increases the cost, but also creates a crisis of competition between humans and animals

Embodiment 1

[0036] A feed additive using perilla to improve the immunity of dairy cows in milk production period, including perilla antibacterial peptide, fermented alfalfa powder, traditional Chinese medicine extract preparation and compound enzyme preparation. The preparation method of the feed additive is as follows: mixing each raw material according to the proportion by weight, adding water to the mixed raw material to immerse the mixed raw material, stirring evenly, and then successively granulating and air-drying to obtain the granular feed additive.

[0037] Perilla antimicrobial peptides in feed additives are prepared by the following steps:

[0038] Step 1. Wash and remove impurities from the perilla seed meal:

[0039] Dry the remaining perilla seed meal after extracting the perilla seed oil and crush it to 50 meshes. Add ethyl acetate to the perilla seed meal powder at a solid-to-liquid ratio of 1g:5mL, and keep the temperature at 30-40°C After stirring for 30 minutes, filter...

Embodiment 2

[0047] The difference between this example and Example 1 is that the parts by weight of the components in the feed additive of this example are as follows: 10-20 parts of Perilla antimicrobial peptide, 30-50 parts of fermented alfalfa powder, 10-20 parts of Chinese medicine extract preparation, 10-15 copies of compound enzyme preparation.

Embodiment 3

[0049] The difference between this example and Example 1 and Example 2 is that the fermented alfalfa powder in the feed additive of this example is obtained by the following method: fresh alfalfa is dried and crushed to 50 mesh, and 100 parts of alfalfa are weighed by weight Powder, 5 parts of molasses, 3 parts of yeast extract and 200 parts of water, after mixing, carry out 121 ℃ autoclaving for 20 minutes to obtain aseptic alfalfa powder material; the number of viable bacteria is 1 × 10 9 CFU of Saccharomyces cerevisiae seed solution and viable count of 1×10 10 The CFU lactic acid bacteria seed solution is respectively added to the alfalfa powder at a volume percentage of 5%, fermented at 37° C. for 36-48 hours, and the fermentation product is filtered to remove water to obtain fermented alfalfa powder.

Abstract

The invention belongs to the technical field of feed additives, and particularly relates to a feed additive for improving immunity of cows in the milk production period by use of perilla and a preparation method of the feed additive. The feed additive comprises perilla antibacterial peptide, fermented alfalfa meal, a traditional Chinese medicine extract preparation and a complex enzyme preparation. The perilla antibacterial peptide is prepared from perilla seed meal left after oil pressing of perilla seeds. The perilla antibacterial peptide acts together with perilla leaf, dandelion, honeysuckle flower, Shuanghuanglian, fructus forsythiae and isatis root extracts with antibacterial and anti-inflammatory effects in the feed additive and can effectively treat and prevent mastitis of the cowsand improve the immunity of the cows in the milk production period. The fermented alfalfa meal, the traditional Chinese medicine extract preparation and the complex enzyme preparation in the feed additive provide a richer and more balanced nutrient basis for the cows and can effectively promote milk secretion and improve the yield and quality of milk, and green milk without hormones, antibioticsand chemical residues can be obtained.

Description

technical field [0001] The invention belongs to the technical field of feed additives, and in particular relates to a feed additive for improving the immunity of dairy cows in milk production period by using perilla and a preparation method thereof. Background technique [0002] In recent years, the dairy farming industry has developed rapidly, and the scale of breeding has continued to expand. The direct impact of the increase in scale is that the breeding density is too high, the growth environment of dairy cows is poor, and they are particularly prone to diseases, and the infection rate of diseases is very high. The level of autoimmunity of animals lower and lower. Large-scale factory-style breeding, excessive breeding density, high production performance and other stresses make dairy cows in a low immune level and sub-health transition, resulting in high morbidity and mortality of animals, bringing a lot of economic losses to farmers, serious Affected breeding efficienc...
