Potentials of poultry offals in African catfish diets
A 70-day feeding trial was conducted to test the effect of partial replacement of fishmeal by poultry offal in African catfish Clarias gariepinus diets. Four isonitrogenous ration containing various levels (0%, control), 30%, 60% and 90% of poultry offal were fed to three replicate groups of C.gariepinus fingerlings with a mean initial weight of 0.74~c 0.15 g. 10 fish/plastic bowl were tested in 15 I capacity plastic bowl. Mean weight gain of the fingerlings fed the control were higher (2.43~c 0.12g) compared to fish fed 30%, 60% and 90% poultry offal inclusion of Hsh meal (1.99~c 0.08g, 1.84~c0.06g and 1.14~c 0.20g, respectively), but there was no significance difference (P~< 0.05) in weight gain of fish. There was no significant variation in feed conversion ratios which varied between 0.46~c 0.12 and 0.53~c 0.20 for the control and 90% poultry offal respectively, obtained among the groups. Similarly, specific growth rate and protein efficiency ratio decreased as the level of poultry offal increased in the diet. It was concluded that the replacement of fish meal with chicken offal meal diet at 30% level will enhance growth performance of Clarias gariepinus
