Growth performance of 6th generation KUB-2 chicken

Abstract

Abstract KUB-2 chicken is an improved local chicken originally from KUB-1 chicken. KUB-2 has been assembled in the Indonesian Research Institute for Animal Production (IRIAP), and it has two sub-populations, namely KUB-2 Balai and KUB-2 kk. KUB-2 has dual purpose functions, for either meat or egg production. For farmers who raise a local chicken to yield meat, growth is an important trait. The study had the objective to evaluate the growth performance of KUB-2 chicken. About 2,540 6th generation KUB-2 chickens, consisting of 1,240 KUB-2 Balai and 1,300 KUB-2 kk were used in the study. Data were analyzed using a t-test. The average ten-week body weight of male and female KUB-2 kk was statistically higher than KUB-2 Balai (P<0.05). The ten-week body weight of KUB-2 Balai and KUB-2 kk chickens were 1,045.91 g and 1,211.80 g for males, and 832.74 g and 956.02 g for females. The feed conversion was 2.81 for KUB-2 Balai and 2.83 for KUB-2 kk chicken. For meat production, KUB-2 kk seemed more profitable compared to KUB-2 Balai since it had higher body weight and similar feed conversion. It also could be yielded at shorter age than KUB-2 Balai for the same body weight.
