Abstract
This study compared egg quality parameters in layers under free-range system with prefabricatedpens and backyard while emphasizing hen age. A total of 300 eggs collected from prefabricatedpens and backyard farming families in the Çamardı District of Niğde Province were used as studymaterials. The assessed external and internal egg quality characteristics included egg weight, shapeindex, shell thickness, shell breaking strength, albumen index, Haugh unit, yolk index, and yolkcolour. The effect of production system on albumen index, Haugh unit, and yolk colour score wasfound statistically significant. There was a significant effect of age on shape index, shell thickness,shell breaking strength, albumen index, Haugh Unit, yolk index, and yolk colour score. The effectof interaction between age and production system was statistically significant for shape index, shellthickness, yolk index, Haugh Unit, and yolk colour score. It was determined that the egg`s meat andblood spots percentages from the free-range and backyard systems were 10.6% and 15.3%,respectively. It was concluded that while eggs produced from free-range system are superior interms of egg weight, shape index, and Haugh unit those obtained from backyard hens are higher ineggshell thickness, eggshell breaking strength, and egg yolk colour.
