What is Non-invasive Broiler Chick Embryo Sexing Based on Opacity Value of Incubated Eggs about?

In boiler production there is a gender biased preference for males, while for layer strains it is females. Thus, there is need for non-intrusive, early sex discrimination of chick embryos that is currently not being met. Hence, the motivation for the current study to investigate sex based growth difference in terms of opacity in order to classify the sex of incubated eggs. As a model, eggs from a broiler strain (ROSS 308) were sorted based on size, mass and shell color, and then incubated. During incubation an Embryonic Vital Scope, which consists of LEDs and a Siphotodiode integrated with amplifire that receives the light that passes through the egg, was used to measure average output voltage for individual eggs. After hatching feather sexing was used to determine the actual gender of the day-old chicks. A two-sample t-test was used to see the significant differences between male and female groups and gender classification model were developed using various algorithms. As the embryo became larger during incubation, the amount of transmitted light was reduced. Consequently, the opacity, the ratio of input LED current over average output voltage, increased. Male chick embryos showed
