The objective of this study was to examine the relationship between polymorphisms of the heart fatty acid binding protein (H-FABP) gene and variation in intramuscular fat (IMF) content, fatty acid composition, and meat quality in Berkshire breed. We detected an association between IMF content and H-FABP HinfI restriction fragment length polymorphism (RFLP) genotype. The HH genotype showed the greatest IMF content among the genotype classes (P<0.05). Regarding meat quality traits, only drip loss was significantly different among the H-FABP HinfI RFLP genotype classes (P<0.01). In the case of fatty acid composition, the degree of saturation of fatty acids was greater in hh-genotype pigs than in HH and Hh genotypes. The H-FABP MspI RFLP genotype affected unsaturated fatty acid content, and the ratio of polyunsaturated fatty acid to saturated fatty acid (P<0.05), whereas the H-FABP HaeIII RFLP genotype had no effect on fatty acid characteristics.
本研究旨在探讨心脏脂肪酸结合蛋白（H-FABP）基因多态性与伯克夏品种猪肌肉内脂肪（IMF）含量、脂肪酸组成和肉质的关系。我们发现 IMF 含量与 H-FABP HinfI 限制片段长度多态性（RFLP）基因型之间存在关联。HH 基因型的 IMF 含量在各基因型类别中最高（P<0.05）。关于肉质特性，只有滴水损失在 H-FABP HinfI RFLP 基因型类别之间存在显著差异（P<0.01）。在脂肪酸组成方面，hh 基因型猪的脂肪酸饱和度大于 HH 和 Hh 基因型。H-FABP MspI RFLP 基因型影响不饱和脂肪酸含量和多不饱和脂肪酸与饱和脂肪酸的比例（P<0.05），而 H-FABP HaeIII RFLP 基因型对脂肪酸特性没有影响。
