Abstract
The impact of dietary fenugreek (FN) supplementation on growth performance, physio-metabolic enzyme response, and antioxi dant enzyme activities in hybrid African catfish (Clarias gariepinus ♀ × Heterobranchus bidorsalis ♂) was investigated in this study.
Five isonitrogenous diets (38% crude protein) were developed and fed to the fish for 60 days. The FN was incorporated into the
diets at 0%, 0.5%, 1.0%, 1.5%, and 2%. Two hundred twenty-five fingerlings of hybrid African catfish (average weight 4.01 g Æ 0.02)
were used for the study and randomly distributed to five dietary groups in triplicate. FN supplementation improved growth
responses and survival rates; the dietary groups considerably (p<0:05) outperformed the control group. FN-based diets consider ably increased the carcass protein content (p ¼ 0:020) and improved protein retention (p ¼ 0:015). FN supplementation markedly
(p<0:001) and dose-dependently reduced the carcass’s lipid content and substantially (p<0:001) increased the levels of metabolic
enzymes. The fish antioxidant capacity was significantly enhanced (p<0:001), and hepatic stress enzymes were greatly (p<0:001)
lowered in FN-based diets. In summary, the second-order polynomial regression analysis indicates that the optimal dose of FN
supplementation to improve hybrid catfish growth without negatively affecting the fish’s physio-metabolic response or overall
wellbeing is 1% dietary inclusion level.
