ABSTRACT

The aim of this study was to evaluate the effects of graded levels 1.3 %) of ginger (Zingiber officinale, Roscoe) (0%, 0.1%, 0.4, 0.7%, 1.0% and 1.3 %) as feed additive in the diets of Clarias gariepinus on growth performance and haematological parameters. This study was carried out to evaluate ginger (Zingiber officinale) for ten weeks to study its effects on Clarias gariepinus. Thus, two hundred and seventy juvenile catfish (Clarias gariepinus) were fed on various levels of supplemental ginger in addition to a control diet (treatmentI) without ginger inclusion. The treatments had 0.1%, 0.4%, 0.7%, 1.0%, 1.3% supplemental ginger inclusion per I00 kg diet respectively.

There were differences (p>0.05) among treatments in all the performance parameters observed. Fish fed 0.7% GPM diet performed significantly (p
