Day old commercial broiler chicks (80 Nos) were reared commonly and given similar managemental inputs during acclimatization period of two weeks. On 15th day the broilers were divided randomly and equally into four groups. Group I (Control) provided with basal diet, in Group II basal diet were supplemented with quercetin @ 100 mg/ kg of diet, in Group III basal diet were supplemented with lycopene @ 100 mg/ kg of diet and in Group IV basal diet were supplemented with quercetin @ 50 mg/ kg + lycopene @ 50 mg/ kg of diet. Blood samples were collected at weekly intervals till the end of the experiment. Haematological, biochemical, antioxidant and growth parameters were measured as per standard protocol. The results showed that the supplementation of quercetin and lycopene significantly (P˂ 0.05) increased Hb, PCV, SOD, GSH-Px levels; significantly (P˂ 0.05) decreased Heterophil (%), Heterophil/Lymphocyte (H/L) ratio, MDA, Cholesterol and Creatinine levels during last week of the study. There was significant (P˂ 0.05) increase in TEC, Catalase and Body weight values; significant (P˂ 0.05) decrease in triglycerides and BUN values during last two weeks of the study. There was marked improvement in body weight gain, feed intake, FCR and Dressing percentage. However, treatments showed no significant (P˃ 0.05) difference in the values of MCV, MCH, MCHC, TLC, Lymphocytes, Monocytes, Eosinophils, Basophils, Glucose, Total protein, Albumin, Globulin and A/G ratio during the study period. It is concluded that the supplementation of quercetin, lycopene and their combination in the diet of broilers have positive influence on heamoto-biochemical, antioxidant and growth parametersThesis
