Evaluation of carcass traits and meat characteristics of Guzerat-crossbred bulls

Our objective was to evaluate carcass and meat characteristics of Guzerat-crossbred bulls finished in feedlot. Carcasses from 18 bulls, randomly selected from a larger group of 36 bulls, consisting of F1 Guzerat x Holstein (Guzholstein); F1 Guzerat x Nellore (Guzonell); and 1/2 Simmental + 1/4 Guzerat + 1/4 Nellore (Three-Cross; n = 6 each group) were used. Cold carcass weight was greater (P = 0.01) for Three-Cross compared with Guzonell and Guzholstein. Three-Cross carcasses had greater (P < 0.01) rib-eye-area and 100-kg-adjusted rib-eye-area among groups. Longissimus lumborum length did not differ (P > 0.05) among groups, but depth was greater (P < 0.01) for Three-Cross compared with other groups. Guzholtein had lesser (P = 0.05) shear force compared with Guzonell, with Three-Cross being intermediate. We conclude that Guzholstein is an adequate option for producers willing to finish this kind of genetic group, as it is comparable or better than Bos indicus crosses and B. indicus x Bos taurus bulls.
