| Abstract | ||
| Reduction of atlatoxicosis in Nile tilapia (Oreochromis niloticus) fish was exmined by adding eight commercial adsorbents from Egyptian market to aflatoxin 8, contaminated diets in a feeding trial for 8 weeks. Twenty hundred and ten growing Nile tilapia (Oreochromis niloticus) fish were assigned to ten experimental diets. There were 3 replicate glass aquariums of 7 fish I replicate. The 1st diet served as a control (commercial diet) (C), the 2nd one was contaminated with 9 mg aflatoxin 8, I Kg diet (A) and the other experimental diets contained the same level 0 f aflatoxin 8, plus 0.5% of adsorbents from I to VIII. Adsorbent I was modified yeast cell wall, II was bentonite, III was tri - star , IV was m ycobond, V was e gy - t ox, VI was m oldstop super, VII was fungstat-k and VIII was moldstop mycobind plus. Aflatoxin 8, caused significantly (P ~ .05) loss in live body weight which was 6.09; 11.25; 17.34 and 22.87% of the treated fish at 2 , 4 , 6 and 8 weeks, respectively. Mortality rate increased significantly (p S 0.05) (47.62 % versus 4.76% for the control) by aflatoxin. Also, aspartate aminotransferase (AST) and alanine aminotransferase (AL T) activites increased Significantly by aflatoxin but the total protein and albumin decreased. Adding the adsorbents caused significantly (P ~ .05) reduce the toxic effect of aflatoxin on loss of body weight (the improvement ranged from 14.53 to 95.57%) according to the kind of adsorbent and experimental duration. Also significantly (P ~ .05) decrease in the mortality rate and improved the blood parameters (ps 0.05) were caused by adsorbents. These results suggested that ac!ding adsorbents specially adsorbent IV (Mycobond) and VI (mold stop super) to fish diet contaminated with aflatoxin 8, had benifical effects in fish feeding. | ||
