The possible LD 50 of endosulfan (<<-isoner) deve loping chick embryo was found to be 5.0 µg at 12 day of incubation through CAM route. 2. Lower concentration (2.0 µg) of endosulfan interferes the normal biochemical functions of the developing chick embryo. 3. The immuno-suppressive action of endosulfan in developing chick embryo warns for failure of future vaccination programme in poultry industry. 4. Use of endosulfan as poultry feed preservative should be restricted. 5. ACH/ATPase activity and SRID-Test may be used as indicator for diagnosis of the endosulfan intoxication of the developing chick embryos in hatcheries.EnglishThesis
