Effects of Zinc Supplementation To Ration on Some Hematological Parameters in Broiler Chicks

Abstract

The aim of the study was to examine the effects of zinc supplementation on some hematological parameters. Sixty newborn male broiler chicks were utilized in the study. Zinc (Zn) was added into drinking water at levels of 0, 125, 500, and 1000 mg/kg. In the study, there was no significant difference between control and Zn-supplemented groups in erythrocyte count, hemoglobin amount, hematocrit levels, total leukocyte count, and differential leukocyte % levels, but the alpha-naphthyl acetate esterase ANAE(+) lymphocyte rate significantly (p< 0.05) increased in the 125-ppm Zn-supplemented group compared with the control group. In conclusion, the data obtained may be beneficial in demonstrating the effects of zinc on, at least, these parameters.
