Description

Poultry breeding seed selection system based on Internet of Things
Technical field
The present invention relates to a kind of Internet of Things technical field of data processing, particularly relate to a kind of poultry breeding seed selection system based on Internet of Things.
Background technology
Improved seeds are one of most important material bases of Developing Modern Livestock Husbandry, the raising animal products market competitiveness, and a key factor that improves family's livestock and poultry level of production is kind.China is animal husbandry production and Consumption of animal by-product big country, but the market competitiveness of poultry prod is not strong, and very important reason is exactly cultivate poultry breeding indifferent.The govern-house-variety that , China animal husbandry is at present used in producing is all Foreign Modern commercial breed, all will spend a large amount of foreign exchanges from external introduction poultry breeding every year.At home, existing independent intellectual property has again the poultry commercial breed national brand of the great market competitiveness and influence power seldom even not have.External animal husbandry developed country is at present in left and right or even monopolize the developing direction in China's animal husbandry and market.This situation serious threat China sustainable development of animal husbandry process, once there is international trade and technology controversial issue or epidemic prevention disease factor, China's animal husbandry will face great kind potential safety hazard.
The American-European animal husbandry developed country that waits has just started poultry business breeding truly as far back as five sixties of last century, the high yield specific breed selecting through their high strength has become the principal item that world's herding is produced, these high yield specific breeds all be take soon long or high yield type as main, can significantly improve animal husbandry output and efficiency, be suitable for the intensive management of fund, technology-intensive type, adapt to very much China's the eighties in last century in economic environment and the herding market demand of Initial stages for reform and opening-up.
Two during the last ten years, and external famous commercial poultry kind has been brought into play great impetus to the development of China's animal husbandry, and herding output improves rapidly, has met the demand of domestic market to poultry prod quantity.
Yet, because the continuous high-strength directional of external high yield specific breed is selected, make in kind, interracial hereditary variation is more and more narrow, finally cause selection limit, simultaneously but continuous decrease of immunity and premunition when production performance improves constantly, faces larger epidemic disease risk (after kind unification, some susceptible epidemic disease easily being propagated in the world).And, top core kind fowl resource long-term dependence on import in the breeding of method of China most of breeding enterprise, vicious circle in " introduce a fine variety → maintain → degenerate → introduce a fine variety again " for a long time, Post-WTO, many exotic poultry specialized company directly enters Chinese market, and the form that domestic kind of poultry farm faces is very severe.
Meanwhile, along with China's rapid economic development, there is great variety in product consumption relation between market supply and demand, people are changed to mass type direction by scalar type the demand of animal food, and more and more higher to animal food quality requirements, abroad these unification kinds can not meet the need.And the good characteristics such as the many local poultry kinds of China not only have that meat is good, unique flavor, ripe morning, and there is stronger resistance against diseases and resistance, very applicable consumer demand.Therefore, rationally utilize national genetic resources, cultivate the inevitable choice of poultry new varieties ,Shi with Chinese characteristics China animal husbandry development.
But, in current traditional normal poultry breeding seed selection process, poultry breeding seed selection system mainly relies on staff to complete, and cannot guarantee promptness and accuracy at all, thereby cause the data of breeding seed selection system unreliable, cannot complete well the seed selection of science poultry breeding.
China scientific and technological circle and relevant breeding enterprise attempt utilizing good poultry kind genetic resources both domestic and external to form the corollary system of oneself always, but these effort rarely have successfully, and mainly there are the following problems:
