Meat production traits of Angora goat 1: fattening, slaughter, and carcass characteristics of intact and castrated kids


Fattening performance, slaughter, and carcass traits of intact and castrated Angora goat kids slaughtered at different slaughter weights were examined. A total of 96 (48 intact, I-kids, and 48 castrated, C-kids) single Angora kids were fattened, and 48 of them (24 I-kids and 24 C-kids) were slaughtered at slaughter weights (SW) of 20, 25, and 30 kg. Castration negatively affected fattening performance, and the kids showed rising daily weight gain with increasing SW. While dressing percentages were not affected by castration, it caused a tendency for a decrease in offal. However, with the increase in SW, dressing percentages increased, and offal decreased. Castration increased non-carcass fat percentages and back fat depth. The proportions of individual cuts did not generally vary because of castration but changed with SW; foreleg percentages decreased (P < 0.001) while neck percentages increased (P < 0.05). Carcass composition was affected by castration; the percentages of carcass lean (P < 0.001) and bone (P < 0.01) dropped, and total fat (P < 0.001) increased. SW had an impact on carcass composition; the percentages of carcass bone (P < 0.001) declined, and lean (P < 0.001) and total fat (P < 0.001) raised as SW increased. The lean/fat ratio was affected by castration (P < 0.001) and increasing SW (P < 0.05). Castration reduced the lean percentage in all cuts. The leg showed the highest lean percentage, whereas the greatest fat ratio was found in the breast+flank in all SW groups. Consequently, castration of Angora male kids negatively affected fattening performance and altered the carcass composition, while the increase in slaughter weight improved fattening performance and slaughter and carcass characteristics.
