Abstract :Kacang goat insert ignore into journalissuearticles values(Capra hircus); is one of Indonesian germ plasm and kept by smallholders for meat production. This research was carried out to obtain the growth curve of body weight from 1 to 24 months of age in Kacang goats managed by smallholders at Tambang District of Indonesia. Total of 100 goats insert ignore into journalissuearticles values(51 buck and 49 does); were used in this study to obtain Logistic and Gompertz growth curves. Research showed that the Logistic and Gompertz growth curve have similar of coefficient of determination value insert ignore into journalissuearticles values(R2= 0.98);. However, the standard error insert ignore into journalissuearticles values(SE); value in Gompertz was lower than Logistic curves. The inflection weight insert ignore into journalissuearticles values(IW); was reached of 13.16 to 15.30 kg insert ignore into journalissuearticles values(Logistic); and 12.76 to 14.41 kg insert ignore into journalissuearticles values(Gompertz);. The inflection age insert ignore into journalissuearticles values(IA); was reached of 12.95 to 15.57 months insert ignore into journalissuearticles values(Logistic); and 12.71 to14.41 months insert ignore into journalissuearticles values(Gompertz);. The growth rate insert ignore into journalissuearticles values(GR); were reached of 1.06 to 1.23 kg/month insert ignore into journalissuearticles values(Logistic); and 1.02 to 1.10 kg/month insert ignore into journalissuearticles values(Gompertz);. It was concluded that Gompertz growth curve was the best predictor to predict body weight in Kacang goats.
