Problems solved by technology

Sperm protein markers can help distinguish fertile sperm from sterile sperm, but related research is still in its infancy, and the reliability of sperm protein markers still needs to be verified in clinical trials (Kwon et al., 2015)

Embodiment 1

[0033] The present invention has two core technical links: (1) the establishment of the sperm protein marker SPACA4 related to the reproductive performance of a boar;

[0034] (2) Using the SPACA4 protein marker to realize the breeding of high reproductive performance boars.

[0035] Specific steps are as follows:

[0036] (1) Establishment of the sperm protein marker SPACA4 related to the reproductive performance of boars

[0037] In order to establish semen protein markers that can reflect the reproductive performance of boars and be used for breeding boars with high reproductive performance, the following work was carried out in this study:

[0038] (1) Scientifically and rationally select representative breeding boars as the research object based on the existing breeding performance.

[0039] According to the breeding performance records of breeding boars, important production indicators (mating farrowing rate, average litter size, average litter size and reproductive ef...

Abstract

The invention discloses a sperm protein marker SPACA4 closely related to the reproductive performance of boars and its application. The invention provides a new sperm protein marker SPACA4 which is closely related to the reproductive performance of boars, and its relative content is significantly positively correlated with the reproductive performance of boars. The fertilization ability and reproductive performance of pig semen can be used to accurately evaluate the reproductive performance of existing boars. In production, the protein marker can be used to more accurately select and breed high-reproductive boars. Elimination of boars with poor reproductive performance is conducive to improving the reproductive performance and economic benefits of pig farms. It is convenient to use in production, and it only needs to detect the content of the semen protein marker SPACA4, and will not cause boar sampling damage and stress.

Description

technical field [0001] The invention relates to a sperm protein marker SPACA4 for breeding boars with high reproductive performance, in particular to a significant positive correlation between the relative content of the boar sperm protein SPACA4 and the reproductive performance of the boar, by measuring the relative content of the sperm protein SPACA4, It is used to judge the fertilization ability and reproductive performance of boar semen, so as to select breeding boars with high reproductive performance from the boar population. 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 low heritability traits cont...
