GROWTH PERFORMANCE OF KUB AND SABU CHICKEN IN EAST NUSA TENGGARA PROVINCE

Abstract

ABSTRACT

The objective of this study was to evaluate growth performance of 50% pure bred x 50% cross
bred chickens under semi intensive management system. Pure and cross bred chickens were evaluated
for growth performance from 2 weeks to 7 weeks of age. The chickens were raised under a deep
litter house system and provided with water and commercial feeds ad libitum. There were no
significant differences in body weights of crossbred and pure bred chickens at 4 and 8 weeks of age.
However, at 20 weeks of age, crossbred males were significantly heavier (p<0.05) than purebred . This
might be attributed to the differences in hormonal profile, aggressiveness and dominance of
males when feeding especially when males and females are housed together.

Key words: growth, crossbred, local chickens, purebred.
