Abstract: The dietary effects of Chaya leaf meal as feed additives in the diets of African catfish (Clarias gariepinus) Juveniles of mean average weight (12.5±0.03 g) were investigated for a period of ten weeks. Five experimental diets were formulated at 0% (CYMT), 0.5% (CYMA), 1.0% (CYMB), 1.5% (CYMC), and 2.0% (CYMD) inclusion level of the Chaya leaf meal (CYM). All the diets were iso-nitrogenous (40% crude protein level). A total of three hundred (300) fingerlings randomly allocated in triplicate to fifteen experimental tanks (0.53x0.37x0.25 m dimensions) in a completely randomized design (CRD) and each tank contained 20 fingerlings. Fish were fed at 5% body weight biomass to triplicate treatment. The highest mean weight gain of 48.08±4.75 g was obtained in fish fed control diet, the value was significantly (p<0.05) higher when compared with those obtained in fish fed diets containing various inclusion levels of chaya leaf meal. However, the mean weight gain, percentage weight gain and specific growth rate for all the fish fed control diet and the fish fed dietary treatments maintained similar trend. The best feed conversion ratio (FCR) of 3.27±0.21 was obtained in fish fed control diet while the poorer feed conversion ratio was observed in fish fed diet containing 0.5 to 2% inclusion levels of chaya leaf meal, the feed conversion ratio increased as the level of the leaf meal increases until inclusion level of 1.5% after which a decrease occurred at 2% inclusion level of chaya leaf meal. Similarly, the values of feed efficiency and protein efficiency ratio for all the fish fed control diet and the fish fed containing leaf meal maintained the same trend. The gross feed conversion efficiency decreased as the level of the leaf meal increases in fish fed diet containing 0.5 to 1.5% inclusion level of chaya leaf meal, but an increased was observed at 2% inclusion level of the leaf meal. Further investigation on the utilization of chaya leaf meal in fish feeding and adopting appropriate processing methods for the removal of anti-nutritional factors is desirable.
