Group 4,5 and6 were given a ration containing Baygon in a concentration of 200,400 and 600 ppm respectivelly. Group 7 which was used as a controlwas given a ration without insecticide. Five chickens from eachgroup were sacrificed on the 2nd, 4th, 6th, 8th, l Oth and] 2th week,from the onset of adminstration of the insecticide. The cl inical signs,the pathological findings and the biochemical changes of thesesacrificed chickens were recorded.The characters tic clinical signs in the chickens which weregiven Baygon were depression, loss of the appitite, diarrhea, tremor,high mortality and decrease in the body weight.The macroscopical changes were congestion, haemorrhages in most of the internal organs particularly liver and kidneys in thechicken which were given either Flit or Baygon.The microscopical examination of the internal organs showed dilatation of blood vessels in most of the organs together with perivasculitis.
