Abstract
Dietary and organoleptic qualities of pork products are largely influenced by the profiles of fatty acids (FAs) of meat and fat. The objective of this work was to investigate the potential associations between FA profile in subcutaneous adipose (back fat and leg fat) and muscular (longissimus dorsi and biceps femoris) tissues in heavy pigs (n = 129, 9-month-old) with single nucleotide polymorphisms (SNPs) in six candidate genes involved in fat metabolism: Stearoyl-CoA desaturase (SCD), Diacylglycerol acyltransferase 1 and 2 (DGAT1 &DGAT2), Microsomal Triglyceride Transfer Protein (MTTP), Fatty Acid Synthase (FASN) and Heart- fatty acid binding protein (H-FABP). Preliminary results suggest a putative association between MTTP, DGAT2 and FASN and the FA content in both fat and meat, whereas between DGAT1, SCD and H-FABP the association was found in adipose tissue only. However, the effect of the analyzed genes, needs to be verified in a larger and better characterized pig population to support the hypothesized associations with FA content.
