The objective of this research was to evaluate the source and extent of tropical adaptation affecting feedlot and carcass traits. Calves of Brangus (BN) dams were sired by Braford (BFBN; n = 63; 38% Brahman), Hereford (HEBN; n = 38; 19% Brahman), and Bonsmara (BOBN; n = 53; 19% Brahman and 31% Africander) sires. Calves of Angus (AN) dams were sired by Hereford (HEAN; n = 38) and Bonsmara (BOAN; n = 45; 31% Africander) sires. Carcass yield and LM area were greater (P 0.15) in Warner-Bratzler shear force values. Presence of Brahman breeding (BN) in the dam breed positively affected weight traits, whereas absence of Brahman breeding (AN) positively affected carcass merit traits. In terms of sire breed contributions, neither extent nor source of tropical adaptation provided a distinct overall advantage in this study. |
