| dc.description.abstract | The heart fatty acid-binding protein (H-FABP) gene is generally considered to
be a candidate gene for fatness traits in pigs. In this study, the genetic variation
of the second intron in porcine H-FABP gene was investigated in 200 pigs.
Polymorphism of single nucleotide at the position 1811 bp was detected by HFABP/
HaeIII. In the whole examined animal group, the heterozygote genotype Dd
was the most frequency (0.375) while the homozygote dd had the lowest
frequency (0.295). The statistical analysis showed the significant differences in
IMF content as well as backfat depth (BFD), ADG, and loin depth (LD) between HFABP/
HaeIII genotypes. The ADG, BFD and LD ordered by H-FABP genotypes were
dd > DD > Dd, while the IMF was ordered as Dd > DD > dd. However, the
differences between DD and Dd are not significant. This paper partly contributed
to the whole study for the association between H-FABP gene and IMF content. It
provided useful database for the further molecular selective breeding of meat
quality traits. H-FABP gene can be considered as genetic marker to identify or
track the source of genetic material in IMF improvement by selective breeding.
