Fifty-three unrelated Piemontese subjects, representative of the breed, were tested for CAPN1 g.5709G>C (AF252504), CAPN1 g.6545C>T (AF248054), and CAST g.282C>G (AY008267) mutations; seventy meat samples from commercial Piemontese animals were genotyped for the three SNPs and tenderness was measured as shear force (WBs) at different days post-mortem. The frequencies of the C alleles, shown to be associated with improved tenderness, were 0.14 for CAPN1 5709, 0.52 for CAPN1 6545 and 0.63 for CAST 282. Significant associations with meat tenderness (P=0.01) were observed only for the CAST 282 marker, with a favourable effect of the C allele, consistent during the ageing (–1.997 kg at day 1 to –0.956 kg at day 11).

Abstract
Fifty-three unrelated Piemontese subjects, representative of the breed, were tested for CAPN1 g.5709G>C (AF252504), CAPN1 g.6545C>T (AF248054), and CAST g.282C>G (AY008267) mutations; seventy meat samples from commercial Piemontese animals were genotyped for the three SNPs and tenderness was measured as shear force (WBs) at different days post-mortem. The frequencies of the C alleles, shown to be associated with improved tenderness, were 0.14 for CAPN1 5709, 0.52 for CAPN1 6545 and 0.63 for CAST 282. Significant associations with meat tenderness (P=0.01) were observed only for the CAST 282 marker, with a favourable effect of the C allele, consistent during the ageing (–1.997 kg at day 1 to –0.956 kg at day 11).
