| Abstract - The objective of this work was to estimate the allelic and genotypic frequencies of CAST/XmnI, a calpastatin gene polymorphism, and CAPN530, a calpain 1 large subunit gene polymorphism, in different beef genetic groups (Nelore and Nelore x Bos taurus), and to investigate associations between these polymorphisms and carcass and meat traits. Three hundred animals ? comprising 114 Nelore, 67 Angus x Nelore, 44 Rubia Gallega x Nelore, 41 Canchim, 19 Brangus three-way cross and 15 Braunvieh three-way cross ? were genotyped by PCR-RFLP and phenotyped for rib-eye area (REA), back-fat thickness (BT), intramuscular fat (IF), shear force (SF) and myofibrillar fragmentation index (MFI). The occurrence of the two alleles of the CAST/XmnI and CAPN530 single... |

| The objectives of the study were toevaluate allelic frequencies and to test the associationof polymorphisms in the calpastatin (CAST) andμ-calpain (CAPN1) genes with meat tenderness in 3French beef breeds. A total of 1,114 Charolais, 1,254Limousin, and 981 Blonde d’Aquitaine purebred youngbulls were genotyped for 3 SNP in the CAST gene and4 SNP in the CAPN1 gene. Two of these markers, 1in each gene, can be found in Australian or Americancommercial genetic tests. Others have previously beenreported in American studies or are newly evidencedSNP. The quantitative traits studied were Warner-Bratzler shear force and a tenderness score evaluatedby trained sensory panels. All the SNP were informativein the 3 breeds. Associations of individual markersor haplotypes... |
