Description
Technical Field
The invention relates to the field of animal breeding, in particular to a pig breeding method based on artificial insemination.
Background
For a long time, the large-scale pig breeding selection generally comprises the independent feeding of great ancestor breeder pig farms, the independent feeding of grand ancestor pigs and the independent feeding of ternary commercial pigs. The replacement of the sows is carried out by supplementing replacement sows from other special breeding farms. Due to the limitation of heredity, each pig farm cannot supplement replacement sows by self in a self-breeding mode. Thus, in the case of transverse african swine fever, replacement sows introduced from other pig farms are likely to infect the swine fever in the pig farm, resulting in great loss to the pig farm. Meanwhile, the reserved sows (boars) purchased outside are often high in price and uneven in quality, so that the pigs are disordered and unstable in production performance, economic benefits fluctuate along with the pigs, and production and operation of a pig farm are not facilitated. Thus, existing pig breeding methods remain to be improved.
Disclosure of Invention
The present invention is directed to solving, at least to some extent, one of the technical problems in the related art. To this end, it is an object of the present invention to propose a method of breeding pigs based on artificial insemination. The pig breeding method can realize the combined breeding and accurate matching of a plurality of pig farms, can realize the self-circulation of sows, reduce the transportation of swineries, and effectively improve the safety and the economic benefit of pig breeding.
In one aspect of the invention, the invention provides a method of breeding pigs based on artificial insemination. According to an embodiment of the present invention, the pig breeding method comprises: breeding through a first breeding field to obtain pure boars and pure sows, selecting seeds, recording information data of the pure boars and the pure sows as A, and submitting the information data to a data center; sending the pure boars subjected to the breeding to a boar station for feeding and training to obtain boar essences, recording information data of the boar essences as B, and submitting the information data to the data center; breeding in a second breeding field to obtain sows, selecting seeds, recording the information data of the pure sows as C, and submitting the information data to the data center; wherein the first breeding farm and the second breeding farm are precisely matched according to the information data A, B and C provided by the data center.
The pig breeding method based on artificial insemination according to the embodiment of the invention is also called 'Prwlett-packard breeding', and comprises two contents of combined breeding and precise matching. The joint breeding is realized by establishing genetic connection between a boar station and a second breeding field (also called a client field) in a first breeding field (also called a core breeding field), simultaneously measuring the core breeding field and the client field, and establishing a data center together. The accurate matching means that the core breeding farm, the boar station and the client farm are matched according to data and possibility provided by the data center so as to obtain the best breeding configuration and economic benefit.
The general breeding system comprises four components of a core breeding field, a boar station, a data center and a client field. Only pure breeding pigs are fed in a core breeding field, continuous breeding of the breeding pigs is improved through a modern breeding technology, and top-grade boars bred in the core breeding field enter a boar station; the boar station only feeds boars, and provides pig essence for a core breeding farm and a client farm; the client farm raises pure sow, binary sow and ternary commercial pig. The client farm carries out pure breeding, expanding breeding and ternary commercial pig production by utilizing the pig essence of the boar station. The sows in the client farm complete self-circulation. The core breeding field and the client field adopt a unified measuring mode, all information data are completely submitted to a data center, and the data center analyzes the data information and guides the seed selection and matching of the core breeding field and the client field. Therefore, the general breeding method provided by the invention not only realizes the combined breeding and accurate matching of a plurality of pig farms, but also realizes the self-circulation of sows, reduces the transportation of pig groups, reduces the risk of diseases, and is a new high-efficiency production mode of live pigs suitable for non-pestilence situations.
In addition, the pig breeding method based on artificial insemination according to the above embodiment of the invention can also have the following additional technical characteristics:
in some embodiments of the invention, the informative data comprises at least one of phenotypic data, genotypic data, pedigree data and environmental factor data.
In some embodiments of the invention, the breeding includes primary selection, weaning selection, nursery selection, performance measurement, selection, and swine renewal.
In some embodiments of the present invention, the indicators for the initial selection include: at least one of lineage number, selection strength, pit index and growth status.
In some embodiments of the invention, the performance measurement comprises: body weight measurement, backfat measurement and eye muscle area measurement.
In some embodiments of the invention, the performance test is performed when the weight of the pig to be tested is 30-115 kg.
In some embodiments of the invention, the swine updating comprises: and (4) utilizing the selected and remained pure boars and pure sows to update the boars.
