The effect of copper sulphate and copper nicotinic acid complex supplementation to laying hens on the heamatological traits

Abstract

The aim of this study investigated the effect of copper sulffate and copper nicotinic acid supplementation to laying hens diet on the heamatological characters. A total of 100 Isa brown hens 65 weeks old were used in this study. Divided into three groups as the following: first group (40 hens) fed on basal diet, second group (30 hens) fed basal diet supplement with copper sulfate (250 mg/kg diet) and third group fed basal diet supplement with copper nicotinic acid (150 mg/kg diet). The addition of copper Compound lead to significant increase (P<0.05) in Red blood cells counts, White Blood cell count, heamoglobin concentration, packed cell volume and red blood indices such as MCH, MCHC in the treated group compared with the control, and significant decrease (P< 0.05) in MCV in treated groups.
