ABSTRACT
The present experiment aimed to analyse effect of egg weight on egg quality traits both external and internal.Experiment was carried out with total of 211 eggs, which were collected from a Vanaraja and Gramapriya birds pooled over the genetic groups . These hens were reared in a deep litter system. Collected eggs were categorized according to weight and classified in different egg groups with a difference of 5g each. The purpose of the study was to determine the effect of egg weight on egg quality traits. Egg weight pooled upto 28 weeks of age was found to have significant (P<0.05) effect on all the egg quality traits. The heavier egg weight groups had higher egg width, shape index, albumen height and yolk height. The absolute weight of albumen, yolk and egg shell were estimated to be more in heavier egg weight groups. The 51-55g egg weight group observed to have higher albumen percent, albumen index, egg length and shell thickness. Shell percent found to be higher both in small and large sized egg groups, suggesting that shell weight of small and large sized eggs had higher shell weight percent than medium size. The egg weight was found to have significant (P<0.05) effect on egg quality traits and heavier egg weight groups had higher estimates for all the egg quality traits except yolk index and yolk percentage.
Key words: Egg Weight, External Egg Quality, Internal Egg Quality.
