Abstract

Nile til apia fingerlings were fed on a basal diet (control) containing 25%
crude protein for 8 weeks at a level of 3% daily of the fish biomass for 6 days a week.
Six fish groups were offered either the control diet, control plus 100 ppb aflatoxin BI
(AFBI) or control plus 100 ppb AFBI plus 1% of either egg shell, betafin, clay or silica.·
The aflatoxic diet led to reductions in final body weight, body gain. daily gain, specific
growth rate, survival rate, feed and nutrients utilization, carcass protein and blood
hemoglobin and uric acid. But, il increased mortality rate. internal organs indices.
carcass fat and ash as well as blood activity of some enzymes. The best feed
additives led to significant overcoming these aflatoxic symptoms were egg shell and
clay.
