Relationship between weight, volume and specific gravity of goose eggs before incubation

In this study, the relationships between the weight, volume and specific gravity of eggs are revealed by calculating egg's volume and specific gravity depending on the weight of the egg, breadth and length, which are only three variables, with mathematical equations. Eggs to three goose genotypes, Grey China, Linda and Native geese from Aksaray region taken from six breeders were used. Eggs (n=481) were weighed and Length, Breadth measurements made with a precision of 0.01 mm. Average weights in genotypes from large to small in Linda, Native and Chinese geese were detected as; 165.9, 137.2 and 131.1 g, respectively, and the average egg volume was found as; 152.0, 126.0 and 120.3 cm3, respectively. Specific gravity from large to small in Linda, China and Native has occurred as; 1.092, 1.091 and 1.089 g/cm3. Egg volume was calculated with mathematical equations and results were close to real, and accordingly the calculated Specific gravity was also detected to be realistic. These results were obtained easily by only three variables, egg weight, and Length and Breadth values. This method can pave the way to obtain a lot of information about the egg with Specific gravity.
