Abstract

The KCNJ11 (potassium inwardly-rectifying channel, subfamily J, member 11) gene is located in BTA15, near a quantitative trait loci for meat tenderness. In this study, single nucleotide polymorphisms (SNPs) were described in KCNJ11 and associated with Warner ? Bratzler shear force (WBSF) at different aging times: 1 d after slaughter (WBSF0), after 7 d (WBSF7) and 14 d (WBSF14) of aging. Fourteen steers of Nelore breed, characterized as extreme for the distribution of WBSF0 in a half-sib population of 500 progenies from 32 sires, were selected for sequencing.P404
