Abstract
A total of 408 day old keets generated from direct and reciprocal crossing of two colour variants of indigenous guinea fowl were used to investigate the effect of crossbreeding on growth at 8 weeks of age in the humid tropical environment. The progeny groups produced were homogenous Pearl variant main cross (PL X PL), homogenous Lavender variant main cross (La X La), Pearl variant reciprocal cross PL X La and Lavender Variant reciprocal cross (La X PL). The experiment was a randomized complete block design with progeny group as treatment and hatch as block. The La X PL progeny had a better FCR compared with other crossbred and their reciprocal crosses indicating that the keets may be good converters of feed. There were no significant difference (P>0.05) in the day-old body weight of the progeny groups, however, significant difference (P

Key words: Crossbreeding, reciprocal crosses, growth performance, guinea fowl
