Abstract

The study was conducted on 33-castrated-male pigs of Landrace x Yorkshire crossbreds to analyze polymorphic association of the H-FABP gene with blood characteristics, growth performance and meat quality traits. As a result, two SNPs (1489C → → T/MspI and 1811C G/HaeIII) were identified in the intron 2 of the candidate gene. Particularly, at the 1489C → T/MspI, the frequency of CC (75.75%) was higher than that of CT (24.24%). None of individual showed TT genotype. Additionally, genotypic frequencies of CG and GG were 27,27% and 72,73% respectively at the SNP 1811C → G/HaeIII. Futhermore, 1489C→T/MspI polymorphic association with HCT 60, PLT 100, Urea 60, BUN 60, loin dry matter, loin crude protein, loin water-holding capacity was statistically significant (p<0.05). Animals with CC genotype showed these traits better than those with CT. Previous studies provided valuable information for definitive role of the H-FABP gene inintramuscular fat, backfat thickness. Here, further evidences for association of the gene with many other traits were added. Therefore, the H-FABP gene may be considered as a good candidate gene for animal breeding programs.
