If the free-range poultry grow and live in a good enclosure, the forage quality they eat is good, the resources are abundant, the drinking water is clean, it meets the sanitary requirements of poultry, the supplementary feed is appropriate, and the quality of the supplementary feed concentrate products is safe. Poultry can be vaccinated regularly according to the immunization program, and veterinary drugs are not used at will during the feeding process. Poultry products that meet these production conditions are completely reliable in safety and have high nutritional value. This product will be favored by consumers, and the price of the product is definitely higher than that of ordinary products. However, at present, the feeding environment of free-range poultry in rural areas of China is relatively poor; The quality of feed products used is unstable, and it is common to feed whatever you want; Some free-range households do not understand the harm of drug abuse and use veterinary drugs at will, which affects product safety. Therefore, at present, the quality of free-range poultry in China is uneven.
