Abstract
An experiment was conducted to determine the effect of dietary inclusion of Mansonia altissima on feed intake, feed efficiency, and feed conversion of laying birds and cocks. A total of 60 birds consisting of 48 layers and 12 cocks were used in a completely randomized design of four treatment groups, A, B, C,D of 15 birds each. Results showed that significant differences (P < 0.05) existed at the level of inclusion of 30 and 40 g/kg feed, respectively. There were no significant differences (P > 0.05) in feed intake (consumption), but there were significant differences (P < 0.05) in feed conversion, between
treatment groups. It was therefore concluded that M. altissima can be used as a growth promoter in chicken at the inclusion level of 30 g/kg feed without causing increased feed consumption by the birds
