Broiler chicken grows fast, is tender, has poor adaptability and disease resistance and high morbidity, and generally adopts daily ration added with antibiotics to prevent broiler chicken diseases in broiler chicken production. However, long-term use of antibiotics can not only cause drug residues in the body. The bacteria can generate drug resistance, and the health of human beings can be seriously threatened through a food chain, so that the improvement of the livestock and poultry health by utilizing natural plants and Chinese herbal medicines is of great interest. The wild buckwheat is a product which is worthy of development. Wild buckwheat rhizome is a local crop with both medicinal and feed, and is distributed in Tibetan, Guizhou, Sichuan, Yunnan, Hubei, Hunan, Jiangsu, Zhejiang, Guangdong, Guangxi and other provinces (regions) of China. The wild buckwheat has no strict requirement on soil, can well grow on barren land and newly reclaimed land, and can be fully utilized for planting in barren mountain fields and gardens in general rural areas. The stem and leaf of the forage grass are tender and succulent, the palatability is good, various livestock and poultry like to eat, and the forage grass is an excellent forage grass resource. The root tuber can be used as a medicine, has physiological functions of immunocompetence, antioxidation, anticancer, bacteriostasis and the like, has wide clinical application in veterinary medicine, and can be used for preventing and treating chicken respiratory tract infection, bacterial diarrhea and staphylococcosis.
The drug effect of the wild buckwheat rhizome is closely related to the growth environment, the morphological change of the wild buckwheat rhizome in low altitude areas is obvious, and the drug effect is obviously reduced. The golden buckwheat in Qian is a new variety of pasture used as both medicine and feed, which is bred by taking wild golden buckwheat in Guizhou province as an original material through a system. Examined by the national grass variety examination committee in 2019, and the variety registration number: 581 and is suitable for cultivation in the area with the altitude of 800-1800 m in Guizhou province.
The carried research shows that the wild buckwheat rhizome (root of a piece) is added into the broiler feed as a feed additive, so that the oxidation resistance of broiler chickens can be improved, the immunity function of organisms can be enhanced, the weight gain of the broiler chickens can be reduced, and in addition, the report that the wild buckwheat rhizome (root of a piece) is added into the broiler feed to improve the production performance of the broiler chickens is not seen.
