| dc.description.abstract | This study investigated the growth performance, nutrients utilization and haematology of Clarias gariepinus juveniles fed with graded activated charcoal (AC) in rice husk (RH) diet. Eight diets were formulated; control diet 1 (without RH and AC), control diet 2 (+AC), diet 3 (2.5%RH), diet 4 (2.5%RH+AC), diet 5 (5.0%RH), diet 6 (5.0%RH+AC), diet 7 (7.5% RH), diet 8 (7.5%RH+AC). Diets were fed to triplicate groups of ten fish per tank thrice daily to satiation for eight weeks. Fish fed Diet 4 recorded highest values for mean weight gain (MWG) (75.71±1.76g), Specific Growth Rate or SGR (2.40±0.03%/day) and Protein E f f i c i e n c y R a t i o ( PER) (3.22±0.15) while fish fed Diet 7 had the least values for Mean Weight Gain or MWG (59.50±1.21g), SGR (2.09±0.03g) and PER (2.39±0.10). The AFI didn’t record significant difference (P>0.05) while FCR had significant difference (P<0.05) across diets, with Diet 4 having the best value for Feed Conversion Ratio or FCR (0.86±0.04). Diets of RH lowered the cholesterol,Packed Cell Volume (PCV) and Haemoglobin (Hb), levels in the experimental fish though, the inclusion of AC to the test diets resulted in a non-significant increase in the levels of these parameters. The values of White Blood Cells (WBC) and White Blood Cells (RBC) did not show significant differences (P>0.05) amongst diets however, diets 1 and 2 recorded the highest values for WBC (14500±707.11) and RBC (6.15±0.91) with the least values (9000±2828.43, 5.15±0.21, respectively) for these parameters recorded with diets 3 and 7. The improved growth recorded at 2.5% inclusion level of AC suggests that activated charcoal could favourably be added to the feed of C. gariepinus juveniles. | en_US |
