Comparison of Egg Quality and Microbiology Traits in Eggs Obtained Different Genotypes under Different Storage Conditions

The present study was conducted to compare egg quality and microbiology traits in eggs from different genotypes under different storage conditions. A total of 880 eggs, obtained from Nick Chick, Dekalb, Lohmann Brown and Atabey (Native Hybrid) hens, flocks aged 56 weeks, were used in the experiment. The eggs were divided into two groups which were stored in wholesaler conditions and consumer conditions for 4 weeks during summer season. External and internal quality traits of eggs and mold-yeast and total bacteria levels were measured. Egg quality criteria results suggest that Lohmann eggs are less affected by wholesaler conditions. Haugh unit, which is an important indicator of albumin quality, was least effective in Atabey eggs stored under wholesaler conditions. The microorganism load of the eggshell did not increase under both store conditions. The total amount of microorganisms, mold and yeast were generally acceptable limits at the end of the 4th week.
