To study the Histopathological changes and tissue residue deposition in broiler birds following profenofos administration. Twenty birds were divided into two groups, 10 in each group. Group I served as control and group II was treated with single oral dose of Profenofos (16 mg/kg). Representative pieces of tissues from liver, kidney, lung, brain and muscle were collected for histopathological examination and residue estimation. Birds treated with profenofos showed marked histopathological changes. Cellular swelling, coagulative necrosis, hydropic degeneration and congestion were observed in most of the tissue examined. | Histopathological changes and tissue residue deposition in broiler birds following profenofos administration
