Abstract

Egg geometrical calculations that include estimations of volume and surface areas are important for the poultry industry and in biological studies, as they can be used in research on population and ecological morphology, and to predict chick weight, egg hatchability, shell quality characteristics, and egg interior parameters. The research reported here is directed at the prediction of egg volume and surface area, and develops a formula that could be both accurate and suitable for calculations. The objective of this research was to improve the accuracy of the calculations of egg volume and surface area based on the measurements of the egg length and breadth. The experiment was carried out with 90 fresh eggs from a flock of Hy-Line Brown chicks at the age of 65 wk. The resulting formula for egg volume, V, was V = (0.6057 − 0.0018B)LB2 in which L is the egg length in millimeters, and B is the egg maximum breadth in millimeters. Egg surface area, S, was calculated as S = (3.155 − 0.0136L + 0.0115B)LB, in which both L and B are taken in millimeters.
