Investigation of Some Mathematical Formulas Developed for Different Bird Eggs in Guinea Fowl Eggs

This study aimed to examine the applicability of formulas determined in eggs of different poultry species to guinea fowl, particularly in terms of egg shell and shape characteristics. In this study, 69 eggs from guinea fowl (Numida melagris) raised as a hobby in the districts of Antakya and Ereğli were used. Individual egg weights were weighed using an electronic scale. The length and width of the egg were determined using two different methods: the first was measurement with calipers, and the second was mathematical calculation. The mathematical equations used for egg length and width values are: Eq.-1 (14.7 × (Egg weight)0.341), Eq.-2 (13.04938 × (Egg weight)0.373272), Eq.-3 (11.3 × (Egg weight)0.327) and Eq.-4 (8.01571 × (Egg weight)0.448338). In addition, some external quality characteristics have been calculated using mathematical formulas based solely on egg weight. Statistically significant differences were found between the determination methods for all external quality characteristics of guinea fowl eggs (P
