| The present study was carried out at the Department of Poultry and Fish production, Faculty of Agriculture, Shibin El-Kom, Menoufia University. The experiment was extended from Oct. 2020 to Nov. 2020, in order to investigate the relationship between in ovo injected Vitamin D3 and its effect on chicken performance, hatchability, mortality, some blood properties and immunity. - The studied traits were as follow: Body weights at different ages, feed consumption (FC) (kg per bird/cycle), feed conversion ratio FCR, titration and calculation of antibody titers and, blood characteristics and liver enzymes. The results indicated that all traits were significantly affected by injected by VD3 levels. | ||||
