Abstract:
A study was carried out to analyse the performance of frizzle and cross bred naked-neck frizzle chicken population under
various farm management systems. The results of the study revealed that the mean body weights of both sexes of both chicken
populations were not significantly different (P<0.05) in all management systems. The age at first laying was significantly early
(P>0.05) in frizzle (7.02±0.04months) and naked-neck frizzle (6.93±0.11 months) in extensive system. The mean monthly egg
production was significantly higher (P>0.05) for both genotypes under intensive system. The average egg weight (46-47g)
and hatchability (76-79%) were significantly higher (P>0.05) in the semi-intensive system. The productive period and life time
were significantly longer (P>0.05) under the extensive system for both populations. It was concluded that, both the populations
performed well in intensive and semi-intensive management systems with respect to different productive traits.
