				Abstract 
 
				Aim: 
				The present 
				study was aimed to investigate the immunological competence of 
				chlorpyrifos (CPF) insecticide after oral administration in 
				layer chickens.  
				Materials and 
				Methods: 
				A total of 20 
				White Leghorn birds were given CPF in drinking water at 0.3 ppm/bird/day 
				(no observable effect level dose) for a period of 3-month. 
				Immune competence status of layer birds and chicks hatched from 
				CPF-treated birds were estimated at 15 days interval in layer 
				birds and monthly interval in chicks using immunological and 
				biochemical parameters.  
				Results:
				There 
				was a significant decrease in values of total leukocytes count, 
				absolute lymphocyte count, absolute heterophil count, total 
				serum protein, serum albumin, serum globulin, and serum gamma 
				globulin in the birds treated with CPF as compared to control. 
				Similarly, immune competence tests such as lymphocyte 
				stimulation test, oxidative burst assay, and enzyme-linked 
				immunosorbent assay tests indicated lower immunity in birds 
				treated with CPF as compared to control. Subsequently, chicks 
				produced from CPF-treated birds were also examined for immune 
				competence, but no significant difference was observed between 
				chicks of both the groups.  
				Conclusion:
				The 
				exposure to CPF produced hemo-biochemical and other changes that 
				could be correlated with changes in the immunological profile of 
				layer chickens suggesting total stoppage of using CPF in poultry 
				sheds.
