The effects of live weight of Japan quails (Coturnix coturnix japonica) on the characteristics of Interior and exterior quality of eggs

Abstract

This study was done in order to figure out between the live weight and the characteristics of interior and exterior quality of eggs. Total 75 quails are used as animal material in this study. The quails are kept in the cages throughout the study and a male + two female quails in equal weights are put to each cage compartment. Eggs are collected from the quails throughout 4 weeks. Some characteristics like the egg weight, shape index, specific gravity, shell thickness, albumen index, yolk index, yolk weight and albumen weight were measured. According to the results of this trail, the egg weight increases depending upon the body weight of the quails selected for live weight. This increase on the egg weight is due the higher albumen and yolk weight. It was observed that the differences between the live weight and egg weight, shape index, albumen and yolk weight were statistically significant (p<0.05).
