Abstract
A ten week feeding experiment was carried out in order to examine the effect of replacing dicalcium phosphate
(DCP) with milled Quail Egg Shells (QES) on the growth performance, haematology and biochemical parameters
of Clarias gariepinus juveniles. A control experiment was set up with 39% crude protein diet. One hundred and
fifty juveniles of Clarias gariepinus with weight range 213.0 – 215.0 g (mean weight: 213.6 ± 0.55) was fed for
ten weeks on, 0, 25, 50, 75 and 100% inclusion levels of QES as a substitute for dicalcium phosphate. The results
show that, highest mean weight gain (MWG) was recorded in fish fed 50% QES-based diet (44.06±7.09 g), while
the lowest weight gain was recorded on the fish fed control diet (25.62±10.16 g). In the haematological parameters,
the fish fed 50% egg shell had the highest packed cell volume (PCV) (38.90±0.87 g/l) and the white blood cell
count (WBC) (162.60±2.71 x 109 G), while the biochemical analysis showed that the fish fed 25% eggshell diet
had the best values (13.88 ± 0.62 mg/gl; 2.00 ± 2.00 mg/gel) in urea and alkaline phosphatase (ALP) respectively.
It is concluded, based on the growth performance and haematological parameters that the 50% dicalcium
phosphate can be replaced by milled quail egg shells in the diet of Clarias gariepinus juveniles... Although it
showed a slight decrease in the biochemical parameters, it had no negative impact on the health status of the
species.
