In recent years, China's animal husbandry has often been affected by epidemics, and antibiotics have been widely used as a conventional feed additive for animal husbandry. However, because of its prone to drug residues, drug resistance, and toxic and side effects on animal organisms, as well as abuse and blind use in livestock production and application, the incidence of various infectious diseases has risen sharply. At present, the search for feed additives with little side effects and significant effects has become a major issue that needs to be solved in livestock and poultry production. Chinese herbal medicine additives have attracted people's attention due to their natural, small side effects, remarkable curative effect, both drug and nutritive properties. Huangqi has been increasingly used in animal husbandry as a traditional Chinese herb additive for Fuben. Industry production. The pharmacological effects of Huangqi The most active ingredient in Astragalus membranaceus is astragalus polysaccharides, which is the main component of Astragalus membranaceus exerting immunopotentiation. Some scholars have used newly hatched chicks with immature immune function as a model to study the effects of APS on immune function. The results showed that a certain concentration of Astragalus polysaccharides can significantly reduce the incidence and mortality of newborn chickens. Astragalus polysaccharides have antiviral and antibacterial effects in addition to enhancing immunity. Jaundice can prevent colds and can reduce the incidence of 50%. Astragalus has a certain effect on porcine circovirus disease, infectious bursal disease, chicken Marek's disease, chicken Newcastle disease, and influenza virus infection. Its inhibitory effect on the virus increases with increasing concentration. Application in chicken farming The use of astragalus-based and other Chinese herbal medicine supplemented groups can significantly increase the egg laying rate of more than 7%, feed remuneration can be increased by more than 15%. Adding 1% astragalus powder to the diet of 1-week-old chicks can significantly increase the appetite, enhance digestive abilities, increase disease resistance, and greatly reduce the mortality of chicks. Adding 0.3% dose to summer diets can reduce the heat stress of laying hens, significantly increase the laying rate of laying hens, reduce the feed-to-egg ratio and the mortality of laying hens, and can improve the quality of eggs. Adding 1% of the added amount to the broiler feed can significantly increase the body weight of the broiler by more than 5% and the feed conversion rate by 9%. It can also increase the antibody titer of chicken serum Newcastle disease and reduce the cholesterol content of the chicken. Application in pig industry Adding astragalus to the diet of weaned piglets can significantly improve the body's immune function, effectively eliminate the immunosuppressive effects caused by early weaning stress, and significantly reduce the rate of diarrhea. Adding 0.05% of astragalus polysaccharides to the diet can increase the digestibility of nutrients in weaned piglets and increase the weight gain of piglets. The 1.5% astragalus powder was added to the feed of weaned piglets and was continuously fed at a low temperature of 12°C for 14 days. The results showed that the experimental group could effectively reduce the impact of cold stress on weaned piglets, and the daily gain was greater than the control. The group increased by 75% and had better resistance to disease and growth. Adding 600-800 mg/kg of Astragalus to pig diets can increase pig weight gain by 20% to 30% and feed utilization by 15%. The group consisting mainly of astragalus is added to piglet feed in a ratio of 0.5%, which has a significant preventive effect on common diseases such as colds and enteritis. Application in aquaculture Adding 1% of astragalus polysaccharides to the feed can increase the weight gain of the squid by 7.36%, and the feed coefficient also decreases. Adding the scutellaria baicalensis to the feed of the scutellaria baicalensis can also significantly increase the weight gain rate of the scutellaria baicalensis, indicating that the polysaccharide of the scutellaria baicalensis has obvious promotion.
