Additive effects of the capn1_187 genotype and ageing on tenderness in representative purebred South African beef bulls. *TT—the genotype that favored tenderness. Within each ageing period, different ascending letter superscripts (a, b) were significantly different p ≤ 0.05), and those that tended to be significantly different p ≤ 0.10) were indicated with different descending letter superscripts (z, y): (a) Warner–Bratzler shear force (WBSF); the effect on d 20 only tended to be significant after FDR adjustment (adjusted p ≤ 0.0558); (b) calpain protease activities.
