Combination of synthetic carotenoids enhanced the haematological attributes in broiler breeders

Abstract

A biological trial was conducted to assess the effect of feeding carotenoid combinations on haematological constituents in broiler breeders. Sixty adult healthy birds were used and these were randomly divided into three groups. The treatments were control (basal diet), T1 (6 mg each of canthaxanthin and apo- carotenoid) and T2 (12 mg each of canthaxanthin and apo- carotenoid). The blood sample was collected and haematological profiles were analysed. In female broilers, higher dose of carotenoids (T2) fed group showed significantly (P0.05) difference in white blood cell, monocyte and red blood cells diameter (RDWc) was observed. In case of male breeders, feeding carotenoids combination showed significantly (P
