Abstract:
A total of 55 fresh eggs of indigenous chicken of Chotanagpur plateau of Jharkhand reared under intensive system of management were collected at 30 weeks of age and studied for its egg quality traits. The average values of egg quality traits viz. egg weight (g), shape index (%), yolk index (%), albumen index (%), yolk index (%), shell thickness (mm) and Haugh unit were observed to be 41.055 ± 0.646, 75.451± 0.325, 12.409 ± 0.157, 48.124 ± 0.159, 0.375 ± 0.004 and 89.373 ± 0.383 respectively. The values of correlation coefficient of egg weight with egg length, egg width, albumen width, albumen height, yolk width and yolk height were 0.927, 0.824, 0.747, 0.334, 0.683, 0.521 respectively. However, the values of correlation coefficient of egg weight with shape index, albumen index, yolk index, shell thickness and Haugh unit were -0.244, -0.289, -0.348, -0.129 and -0.232 respectively. The native chickens are mainly reared by rural poultry farmers under backyard system. The present study was conducted to evaluate the egg quality traits of indigenous chicken under intensive system. The egg quality traits of indigenous chicken of Chotanagpur plateau of Jharkhand were good at the organized farm conditions.
