Abstract : The current study aimed to demonstrate the effect of maca powder feeding on hematological parameters and hormones balance in broiler chicken. 80 Ross chicks were utilized in present experiment and distributed into 4 groups (control, 5%, 10% and 15%). The experiment results demonstrated red blood cells (RBC) counts, hemoglobin (Hb) concentration and package cell volume (PCV) in treated groups (5%, 10% and 15%) exhibited significant (P<0.05) increased compared with control group. While, white blood cells (WBC) counts exhibited significant (P<0.05) decreased compared with control group. Otherwise, Total protein in treated groups exhibited significant (P<0.05) increased compared with control group. While, albumin levels in treated groups exhibited non-significant (P<0.05) changes compared with control group. About the hormone levels, Testosterone levels in treated groups exhibited significant (P<0.05) increased compared with control group. While, insulin levels in treated groups exhibited non-significant changes compared with control group. Therefore, it is concluded from the study that adding maca powder to the diet helps to improve the growth of broiler chickens.
