AI Technical Summary
Technical Problem
The prior art is difficult to predict and breed pigs with low feed meat ratio in advance, and there is a lack of effective molecular markers in the determination of feed utilization efficiency.
Method used
By identifying the molecular markers of PPIL4 gene associated with low residual feed intake, specifically located at 16400938 to 16446860 bp on pig chromosome 1, with C/T polymorphism, primers and PCR amplification methods for detection were designed.
Benefits of technology
It is realized that the SNP marker of the PPIL4 gene is screened to low residual feed intake and low feed-meat ratio pig strains are screened, which improves the feed conversion rate and growth rate, and has important economic benefits and social value.

Abstract
The invention belongs to the technical field of molecular biology, and discloses a large white pig residual feed intake character related PPIL4 gene molecular marker as well as a detection method and application thereof. The SNP marker is located on a nucleotide sequence of a peptidyl proline isomerase-like protein-4 gene (PPIL4) on a pig chromosome 1, the site is a g.16442886 nucleotide site on the pig chromosome 1 of a reference sequence of an international pig genome version 11.1, the SNP marker has C / T polymorphism, and the SNP marker is significantly related to the residual feed intake character of the large white pig. The SNP marker provided by the invention is related to the residual feed intake character of the pig, the pig strain with low residual feed intake can be screened by identifying the SNP marker, and the obtained pig strain with low feed conversion ratio and high growth speed has important economic benefits and social values.
