The aim of this study was to analyze the biological components of eggs as well as lysozyme activity in relation to the age of hens. The research material consisted of eggs from parent stock of Ross 308 meat chickens. The eggs were evaluated at peak laying, i.e. eggs from 30-week-old hens, and after peak laying, i.e. from hens aged 60 weeks. Ninety eggs were evaluated in each period (180 eggs in total). Egg quality traits were divided into destructive and nondestructive traits. In addition, lysozyme activity in the albumen of the eggs was assessed. The quantitative characteristics of the eggs …

The study was conducted to determine the effect of laying period on egg quality traits as well as the chemical composition of Lindovskaya geese. The egg quality traits were examined by randomly taking a total of 90 eggs on the 45th ± 5, 60th ± 5, and 75th ± 5 days of the laying period from 3-year-old female Lindovskaya geese. It was determined that the effect of the laying period on external quality traits of eggs was statistically nonsignificant (P > 0.05). The effect of laying period on internal quality traits including height, diameter, and index of the yolk and albumen …
