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.
