Description
Technical Field
In particular, the present invention relates to a method for evaluating poultry quality based on habitat location and time of movement.
Background
The poultry production and consumption market in China presents diversified characteristics, although fast large white feather broilers, white feather meat ducks and high-yield laying hens in the market at present occupy the leading position, special products such as yellow feather broilers, local chickens, local eggs and sheldrake do not lack the market foundation, and most of the poultry varieties still adopt the traditional breeding mode. In recent years, on the basis of introducing and absorbing foreign varieties, technologies and management experiences, broiler chickens, laying hens and meat ducks quickly achieve the goal of high yield, and the surplus of the productivity is increasingly obvious after the problem of market shortage is solved, so that the wide attention inside and outside the industry is aroused. These products are not bad from a nutritional point of view, but deviate from the consumer's mind in terms of differentiation, personalization, as market prices are most convincing. Under the current era background of quality consumption at home, the existing poultry product supply system has relatively poor capability of meeting diversified and personalized consumption, surplus products at middle and low ends and in public, insufficient supply of high-end and personalized products, and market details create more opportunities for differentiated competition. At present, the country proposes a supply-side reform, the core of which is to provide a good product which can meet the demand better so as to solve the problem of mismatching of supply and demand, which is believed to bring more dividends to the production of the poultry industry, and the initiative adaptation situation developers will take precedence over the high-value place.
