The Effect of Egg Shape Index on Egg Quality in Partridges

Öz

Objective: The aim of this study was to determine the effects of shape index on internal and external egg quality traits and the relationship between shape index and egg quality traits in Partridges (Alectoris chukar). Materials and Methods: In this study, 155 eggs obtained from partridges raised in cages and approximately 42 weeks of age were used. Eggs were divided into three groups based on their shape index: ≤ 75 (59 eggs), < 76 - 77 > (50 eggs), and ≥ 78 (46 eggs). Each egg was individually numbered and weighed. Measurements were then made using a digital caliper at the points where the long and short axes are the largest. Literature data was used to determine other egg quality traits. The data were subjected to the GLM procedure in the SPSS 21. package program, and correlation analysis was performed to determine the relationship between the variables. Results: While shape index had no effect on eggshell thickness and eggshell ratio from external egg quality traits, its effect on egg weight (P<0.05), egg volume (P>0.01) and eggshell weight was found to be significant (P<0.05). Shape index affected elongation value significantly (P<0.001), and elongation value decreased with increasing shape index. While albumen index, yolk index and haugh unit from internal egg quality traits were significantly affected by shape index (P <0.001; P <0.01; P <0.001); no significant difference was observed in terms of albumen ratio, yolk ratio, yolk/albumen ratio, albumen weight, yolk weight and yolk color. Haugh unit values increased with increasing shape index values. There was a negative correlation between shape index and egg quality traits such as shell thickness, eggshell surface area, eggshell ratio, albumen ratio, egg volume, egg weight and elongation values; a positive correlation was found between unit surface eggshell weight, albumen index, yolk index, yolk ratio, yolk/albumen ratio, haugh unit and yolk color values. Conclusion: Differences between the values obtained in our study and those in the literature may be due to differences in genotype, age, rearing system, care and feeding, environmental conditions, and measurement. Such studies need to be expanded to ensure that the partridge population in Turkey reaches satisfactory levels and generates income for the national economy.
