Abstract

The aim was to assess the effect of animal gender on the beef indices recorded at the abattoir for Aberdeen Angus (AA) cattle. Data (n=1090) was collected from private abattoir slaughtering AA cattle. Information consisted in animal gender, birth and weighing dates, age at slaughtering, liveweight, category, killing out percentage, carcass weight, carcass conformation, and carcass fat coverage. A one-way ANOVA model was used in STATISTICA software to find the effect of animal gender (M-males, F-females and S-steers) on the selected traits. Age at slaughtering was higher in females than in males and steers (25.9 months vs. 19.38 and 19.83 months, respectively, p<0.001). Liveweight at slaughter was higher (p<0.001) in S (625.08 kg) than in M (573.24 kg) and F (564.18 kg). There was a significant effect of gender on carcass weight (p<0.001), the heaviest carcass was observed in S, followed by M and the lightest was in F (342.83 kg, 320.20 kg, and 300.63 kg, respectively). Animal gender had an effect (p<0.001) on killing-out percentage that was 55.86% in M, 54.88% in S and 53.29% in F. Carcass conformation class was around R in all gender classes, higher in S and M compared to F (5.00; 4.95; and 4.51, respectively, p<0.001). Steers had the highest (p<0.05) fat coverage of the carcass (3.56) followed by females (3.37) and males (2.78). In conclusion, we could state that animal gender had a significant effect on beef indices of Aberdeen Angus cattle.
