Effect of Hesperidin added to the diet in physiological traits and sex hormones of males and domestic chickens

This study was conducted at the Poultry Farm Department of Animal production , College of Agriculture, University of Baghdad from 18 / 2 / 2017 to 18 / 8 / 2017 to investigate the effect of dietary supplementation with different levels of Hesperidin to ration in productive , physiological and reproductive performance in local Iraqi Fowl. A total 160 local Fowl were used in (120 females and 40 males) at 18 weeks of age. The chickens were distributed randomly at 20 weeks of age into four treatments ,about one replicate for male and three replicates for females for each treatment .The Chicken were fed along experiment period which 12 week on the same diet conation 17.42% curd protein and 2751.7 kcal metabolic energy /kg feed and the Hesperidin added to the rations from the twenty weeks age until the end of experiment . The Chickens (male and female) were reared at separated cages from each other during the experiment period .The experiment treatments were : T1,control: 0 mg of Hesperidin T2 , 150mg Hesperidin / kg of feed. T3, 300mg Hesperidin / kg of feed and T4, 450mg Hesperidin / kg of feed. The Results showed no significant differences in blood serum traits for concentration of glucose , cholesterol and protein for males and females , while the protein concentration in males revealed the significant improvement in first period and overall mean of experiment and no significant improvement in blood serum concentration of testosterone hormone in males and estrogen and progesterone hormones in females.
