Identification of genes related to intramuscular fat independent of backfat thickness in Duroc pigs using single‐step genome‐wide association

5 monthes ago   |   By Animal Genetics

Summary
Intramuscular fat is an important meat‐quality trait of pigs, which influences pork's shearing force, hydraulics, tenderness and juicy flavor. However, to achieve a higher percentage of lean meat, pigs with lower backfat thickness are intensively selected for, which may lead to a reduction in pork quality. Therefore, the objective of this study was to locate loci that affect IMF without changing BF. A single‐step GWAS was performed on 950 Duroc pigs genotyped by a 50K SNP chip in order to detect genomic variants relevant to IMF and BF. The significant SNPs detected were afterwards...
