An experiment was carried out to investigate the effects of dietary supplementation of quercetin and lycopene on hematological parameters in broilers. 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 parameters were analyzed as per the standard protocol. The results showed that supplementation of quercetin and lycopene significantly (p˂0.05) increased Hb, PCV values; significantly (p˂0.05) decreased Heterophil (%), and Heterophil: Lymphocyte ratios, during last week of the study. There was significant (p˂0.05) increase in TEC values during last two weeks of the study. However, treatments showed no significant (p˃0.05) difference in the values of MCV, MCH, MCHC, TLC, Lymphocytes, Monocytes, Eosinophils and Basophils 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 heamotological parameters.
