Effect of profenofos feeding on food consumption, body weight and tissue residues in chickens

Feeding chickens on profenofoa contaminated food at levels of 50, 100 and 200 ppm resulted in significant decrease in food consumption and body weight with some mortalities in the third week of feeding. In the meantime, profenofos and its metabolites were found to distribute rapidly in the different tissues with a positive relationship between tissue residue levels and the corresponding feeding level tested. On return to normal food free from pesticide these residues dissipated rapidly from the different tissues
