AI Technical Summary

Technical Problem

In the existing technology, the molecular marker research on the IMF trait of Ningxiang pigs has problems such as unstable detection, poor repeatability and high cost, making it difficult to effectively identify and breed Ningxiang pigs with high IMF content.

Method used

Using SNP molecular markers associated with IMF traits and combining with KASP technology, we designed specific primer sets and gene chips to detect the IMF content of Ningxiang pigs and determine the IMF traits by genotype. We also provide the application of SNP molecular markers, primer sets, kits and gene chips.

Benefits of technology

It has achieved rapid, accurate and low-cost identification of IMF content, and can efficiently screen out Ningxiang pig breeds with different IMF contents, supporting the breeding of Ningxiang pigs with high IMF content and the cultivation of Ningxiang pig breeds with excellent meat quality.

Abstract

The present invention discloses a SNP molecular marker associated with the IMF trait of Ningxiang pigs and its application. The SNP molecular marker includes at least one of the SNP1 site, SNP2 site, SNP3 site, SNP4 site, SNP5 site, and SNP6 site. The present invention provides a SNP molecular marker associated with the IMF trait, which can efficiently and accurately identify and screen Ningxiang pig breeds with different IMF contents. It has the characteristics of rapid, accurate, and low-cost detection. It can be used for the detection and application of different Ningxiang pig breeds, providing an indispensable and important tool for the breeding of Ningxiang pig breeds with high IMF content and excellent meat quality, and for improving the quality of Ningxiang pork.
