- Abstract
The purpose of the study is to investigate the effects of white and brown laying hens in various age groups and in different cage floors on egg external quality parameters. In the study, the eggs obtained from commercial white Nick Chick and Nick Brown laying hens raised different floors of the chicken cages (1, 3, 5 floors), and 28, 52 and 70 weeks of age. The project was carried out between 2015 and 2016 years. In order to determine the external quality characteristics of the eggs, the egg weight, specific gravity, shape index, shell thickness, breaking strength and egg shell surface area values were determined. As result, genotype, age and cage floor have a significant effect on egg weight, specific gravity and shell properties (P <0.01). The eggs obtained from Nick brown genotype were heavier and had a higher specific gravity than that of white eggs. Regarding the effects of cage floors on egg quality parameters, the egg weight, shape index, shell thickness, shell surface area parameters were higher in the first floor than that of the other floors (3-5) (P < 0.01). As conclusion, the egg weight and egg specific gravity increases whereas the shell thickness values decreases with aging of the birds.
