Abstract

Carcass characteristics of 117 West African dwarf goat kids (26 males, 29 wethers and 62 females) raised under an extensive system on the plateau of Sankaran, Faranah, Guinea were evaluated. Goats, 12-18 months of age were slaughtered at body weights of 14.5, 19.1 and 19.9 kg, respectively. At a constant body weight, the carcass length was longer (P < 0.05) in the male and castrated kids than those of females. Castration significantly increased external fat score but decreased internal fat. There was an increase in dressing percentage, carcass conformation, carcass compactness, gigot conformation and edible offals by 0.1, 0.2, 0.7, 2.5 and 20.4%, respectively, with each kilogram increase in body weight. Corresponding estimates with each kilogram increase in carcass weight were 0.6, 0.4, 1.5, 4.5 and 1.9%, respectively. When carcass weight was constant, internal fat was significantly lower in castrated kids compared to those in males and females, and external fat score was higher than in males. At constant carcass length, the carcasses of female kids were heavier (P < 0.05) than those of castrated kids. Whengigot length was constant, the carcasses of female and castrated kids had wider (P < 0.05) gigot than those of male kids. All estimates of correlations among carcass traits were in the positive direction. It was concluded that castration increased carcass weight, gigot width, dressing percentage and external fat score but reduced internal fat score. (C) 2001 Published by Elsevier Science B.V.
