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 development of modern animal husbandry, improve one of most important material base of the animal products market competitiveness, and the key factor that improves the tame livestock and poultry level of production is a kind.China is animal husbandry production and livestock products consumption big country, but the market competitiveness of poultry prod is not strong, and very important reasons is exactly cultivate the poultry breeding indifferent.At present, employed govern-house-variety all is external modern Commercial kind in China's animal husbandry is produced, and all will spend a large amount of foreign exchanges from external introduction poultry breeding every year.At home, existing independent intellectual property the great market competitiveness and influence power arranged again poultry commercial breed national brand seldom even do not have.External animal husbandry developed country at present about or even the developing direction in monopolization China's animal husbandry and market.This situation serious threat China sustainable development of animal husbandry process, in case international trade and technological controversial issue or epidemic prevention disease factor occur, China's animal husbandry will face great kind potential safety hazard.
Animal husbandry developed countries such as America and Europe have just begun the commercial breeding of poultry truly as far back as five sixties of last century; The high yield specific breed that selects through their high strength has become the principal item that world's herding is produced; These high yield specific breeds are main with fast length or high yield type all; Can significantly improve animal husbandry output and efficient; Be suitable for the intensive management of fund, technology-intensive type, adapt to very much economic environment and the herding market demand of China's the eighties in last century at the reform and opening-up initial stage.
Two during the last ten years, and external famous commercial poultry kind has been brought into play great impetus to China's Developing of Animal Industry, and the herding output improves rapidly, has satisfied 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 that kind is interior, interracial hereditary variation more and more narrow; Finally cause selection limit, immunity and premunition but continue to descend when production performance improves constantly simultaneously, face bigger eqpidemic disease risk (after the kind unification some susceptible eqpidemic disease being prone to propagate in the world).And; Core stud bird resource long-term dependence on import in top in the breeding of method of China most of breeding enterprise; Be in the vicious circle of " introducing a fine variety → keep → degenerate → introduce a fine variety again " for a long time; After the accession to WTO, many exotic poultry specialized company directly gets into Chinese market, and the form that domestic kind of poultry farm faces is very severe.
Meanwhile; Along with China's rapid economic development; Great variety has taken place in the product consumption relation between market supply and demand; People are changed to the mass type direction by scalar type the demand of animal food, and increasingly high to the animal food quality requirements, and abroad these unification kinds can not address that need.And good characteristics such as the many local poultry kinds of China not only have that meat is good, unique flavor, ripe morning, and has stronger resistance against diseases and resistance, very suitable consumer demand.Therefore, rationally utilizing national genetic resources, cultivate poultry new varieties with Chinese characteristics, is the inevitable choice of China's animal husbandry development.
But; In present traditional normal poultry breeding seed selection process, poultry breeding seed selection system mainly relies on staff to accomplish, and can't guarantee promptness and accuracy at all; Thereby cause the data of breeding seed selection system unreliable, can't accomplish the seed selection of science poultry breeding well.
China scientific and technological circle attempt utilizing good poultry kind genetic resources both domestic and external to form the corollary system of oneself with relevant breeding enterprise always, but these effort rarely have success, mainly have following problem:
1, the collection real-time of stud bird individual data items is relatively poor in the breeding seed selection process, can't satisfy the data accuracy requirement;
2, the frequency acquisition of stud bird individual data items is low excessively in the breeding seed selection process, and sample data is very few, can't satisfy science breeding seed selection needs;
