Abstract

Genetic variability of four polymorphisms (CAPN1, CAST, SCD, and FASN) was evaluated and the relationships between them and the beef quality traits (tenderness and fatty acid composition) in Czech crossbred cattle population were assessed. Totally 331 animals were genotyped using multiplex PCR-RFLP. For the CAST NM174003.2:c.155C>T the CC genotype was associated with higher Warner-Bratzler shear force (CC > CT, P < 0.001; CC > TT, P < 0.05) and our results (CC > TT > CT) suggest a possible effect of overdominance. The CAPN1 AF252504.2:c.947G>C did not significantly influence the beef tenderness (strongly influenced by misbalance between the genotype frequencies) suggesting the breed specific effect of this marker. Our association study of the SCD AB075020:c.878T>C polymorphism revealed a positive effect of allele C on myristoleic acid content (CC > CT > TT, P < 0.01). The significant influence of FASN AF285607:g.17924A>G on fatty acid profile was confirmed in the content of myristoleic acid (AG > GG, P < 0.05), palmitoleic acid (AA > AG > GG, P < 0.05, P < 0.001), stearic acid (AA > GG, P < 0.05), myristic acid (AG > GG, P < 0.05), and palmitic acid (AG > GG, P < 0.05). Thus in our population the SNPs of FASN and SCD appeared to be useful markers for selection of animals according to the fatty acid profile as well as SNP of CAST for beef tenderness.
