Abstract

This experiment was conducted in the fields of the Animal Production department - College of Agriculture - University of Kirkuk, from 7/24/2023 until 10/1/2023. 140 laying hens, 28 weeks old, were used. The birds were randomly distributed into 7 treatments. Each treatment included 5 replicates, with 4 birds per replicate. T1: control treatment. T2: control diet with the addition of pomegranate peel powder at a concentration of 1 g/kg feed. T3: control diet with the addition of pomegranate peel powder at a concentration of 2 g/kg feed. T4: control diet with the addition of ginger tuber powder at a concentration of 1 g/kg feed. T5: control diet with the addition of ginger tuber powder at a concentration of 2 g/kg feed. T6: control diet with the addition of pomegranate peel powder at a concentration of 0.5 g/kg feed + 0.5 g/kg feed ginger tuber powder. T7: control diet with the addition of pomegranate peel powder at a concentration of 1 g/kg feed + 1 g/kg feed ginger tuber powder. In the end of the experiment, blood was withdrawn from chicken for testing. The data was analyzed statistically using SAS, and the differences between the means were tested using the Duncan test at the probability level (P<0.05). The present study indicates, using of 2 g/kg of pomegranate peel powder in the diet of the laying hens decrease the total protein, and Uric acid level on the blood. And also effect on the AST, MDA, and GSH level on the blood.
