Abstract Text:

There is interest in fatty acid composition as an index of meat taste. Stearoyl-CoA desaturase (SCD) is enzyme responsible for the conversion of saturated fatty acids into monounsaturated fatty acid. The objective of this research was to investigate difference of SNPs in the SCD gene of different pig breeds. We analyzed polymorphisms in the SCD gene from six breeds: Large White (W), Landrace (L), Duroc (D), Middle white (MW), Meishan (M) and Agu, which is native pig in Japan. Results on SCD g.-233 C>T, the C allele is major allele in W, D and M, the T allele is major allele in L, MW, Agu. On SCDg.-180 A>G, this SNP is found by this study, W, L, MW, M and Agu have more A allele. Though, D have lots of AG genotypes. These SNPs could be useful to selecting for pigs breeding.
