Embodiment 1

[0032] Two core technical links of the present invention: (1) the establishment of the sperm protein marker IZUMO2 related to the reproductive performance of the boar;

[0033] (2) The application of IZUMO2 protein marker to realize the breeding of high reproductive performance boars.

[0034] Specific steps are as follows:

[0035] (1) Establishment of the sperm protein marker IZUMO2 related to the reproductive performance of boars

[0036] In order to establish the semen protein marker IZUMO2, which can reflect the reproductive performance of boars, for the selection of high reproductive performance boars, the following work was carried out in this study:

[0037] (1) Scientifically and rationally select representative breeding boars as the research object based on the existing breeding performance.

[0038] According to the breeding performance records of breeding boars, important production indicators (mating farrowing rate, average litter size, average litter size and r...

Abstract

The invention discloses a sperm protein marker IZUMO2 closely related to the reproductive performance of a service boar and application of the sperm protein marker IZUMO2. The invention provides the novel sperm protein marker IZUMO2 which is closely related to the reproductive performance of the service boar, and the relative content of the sperm protein marker is significantly and positively correlated with the reproductive performance of the service boar; by detecting the relative content of a sperm protein IZUMO2, the sperm fertilizing capacity and the reproductive performance level of theservice boar can be judged, so that relatively accurate evaluation of the reproductive performance of the existing service boars can be realized; the protein marker can be utilized to accurately select and breed service boars with high reproductive performance in production, the service boars with poor reproductive performance can be removed and eliminated, and the improvements on the reproductiveproduction performance and economic benefits of a pig farm are facilitated. The sperm protein marker IZUMO2 is easy to use in production, the reproductive performance can be judged only through the detection of the content of the sperm protein marker IZUMO2, and no sampling damage and stress of the service boars is caused.

Description

technical field [0001] The invention relates to a sperm protein marker IZUMO2 for breeding boars with high reproductive performance, in particular to the relative content of the boar sperm protein IZUMO2 which is significantly positively correlated with the reproductive performance of the boar. By detecting the relative content of the sperm protein IZUMO2, Just can judge the semen fertilization ability of breeding boar and the level of reproductive performance, thereby select the breeding boar with high reproductive performance from the breeding boar group. Background technique [0002] The improvement of breeds in animal husbandry has always been the core task of animal husbandry science and technology workers, and many breeding techniques for breeding excellent breeds have been established. Improving the reproductive performance of livestock is the main way to improve the production level and economic benefits of farms. However, the reproductive traits of livestock are lo...
