Biological Chinese herbal feed additive for broiler chicken and preparation method thereof

Abstract

The invention discloses a biological Chinese herbal feed additive for broiler chicken. The additive is prepared by microbial fermentation of active pharmaceutical ingredients namely Chinese herbal medicines, wherein the active pharmaceutical ingredients of the Chinese herbal medicines comprise the following components in parts by weight: 1-8 of leguminosae, 2-5 of dryopteris setosa, 0.5-4 of radix isatidis, 0.5-5 of radix polygoni multiflori, 1-6 of hawthorn, 1-4 of fructus ligustri Lucidi, 0.5-5 of folium artemisiae argyi, 1-5 of fructus hordei germinatus and 1-4 of radix glycyrrhizae. By utilizing the biological Chinese herbal feed additive, the average weight of the broiler chicken is obviously increased, and the feed conversion ratio is reduced; the immunoglobulin G (IgG) level and newcastle disease (ND) antibody level of broiler chicken blood serum are obviously improved; and the activities of glutathione peroxidase (GSH-PX) and superoxide dismutase of the broiler chicken blood serum are obviously improved, and the content of malondiadehyde (MDA) of leg muscle is greatly reduced. Experiments show that by utilizing the biological Chinese herbal feed additive, the production performance and chicken quality of the broiler chicken can be improved, and the antioxidant capability and immunity of an organism are increased.

Description

technical field [0001] The invention relates to a traditional Chinese medicine feed additive, in particular to a biological traditional Chinese medicine feed additive for broilers. Background technique [0002] Commercial broiler production is an important industry for the development of my country's animal husbandry industry, and it is also an important pillar for the export of my country's animal husbandry products to earn foreign exchange. For a long time, my country's broiler products have been mainly exported to developed countries such as Europe, America, Japan, and South Korea. These countries have set strict standards for pathogenic microbial contamination and drug residues in imported livestock and poultry products. However, there have always been serious problems in the production of some commercial broilers in my country. The problem of public nuisance has led to the current situation that it is difficult to export broiler products. At the same time, a large number...

AI Technical Summary

Problems solved by technology

[0003] Microecological preparations and traditional Chinese medicine feed additives are safe, efficient, have little toxic and side effects, no residue, and are not easy to produce drug resistance. It has the characteristics of deodorizing the breeding environment and is widely used in animal husbandry. Studies have found that some traditional Chinese medicines have synergistic effects with beneficial microorganisms (Tian Biyun, 1996). The ingredients in traditional Chinese medicine can promote the proliferation of beneficial microorganisms, and beneficial microorganisms can Improve the efficacy of traditional Chinese medicine, so Yu Boyang (1999) pointed out: using some beneficial microorganisms to produce products through fermentation of traditional Chinese medicine can improve the immune function of the body, improve production performance, and produce safe and high-quality chicken products. Promote the development of animal husbandry (Yu Boyang, 1999). Fermented Chinese medicine is a perfect combination of modern biotechnology and Chinese medicine research. Fewer researches on traditional Chinese medicine feed additives for feed

[0004] At present, there are very few studies on livestock and poultry biological traditional Chinese medicine preparations at home and abroad, especially reports on the impact on broiler performance and carcass quality. Biological Chinese medicine additives are a combination of traditional Chinese veterinary theory and modern biotechnology to prepare new biological Chinese medicine preparations , to explore the effects of biological traditional Chinese medicine preparations on the growth performance, carcass quality and meat quality of broilers after replacing antibiotics, and provide a theoretical basis for the production of safe, efficient and high-quality poultry products
