Determination of Egg Internal and External Quality Characteristics with Mathematical Formulas in Guinea Hens

Abstract

This study was carried out to determine some internal and external quality characteristics of 378 eggs collected between March and July from 42-week-old Guinea Hens (Numidae meleagris) raised by the public in Erzincan province, using mathematical formulas. Egg external quality features include shape index 73%, elongation 1.37, egg surface area 55.65 cm2, egg volume 40.39 cm3, shell thickness 0.28 mm, shell weight 3.19 g, number of pores-1 6686.05, number of pores-2 5156.10, number of pores- 3 5043.33 pieces, pore density-1 120.22 pore number/cm2, pore density-2 92.62 pore number/cm2, pore density-3 90.52 pore number/cm2; The yolk weight and white weight of the egg were determined as 6.02 g and 30.89 g, from the egg internal quality characteristics. As a result, in this study, yolk weight, shell weight and shell thickness values of egg internal and external quality characteristics calculated using mathematical formulas based on egg weight without spoiling the egg integrity were found to be lower than the values in some studies determined by measurement, while the white weight value was found to be higher.
