Abstract

Determining the sex of the embryo during incubation is crucial for the poultry industry. The primary problem to comprehend in this study is the manipulation of the sex ratio and also the egg production. The study will concentrate on how two distinct methods of pairing parents—one male with one female and another male with three females—affect egg production, the average egg mass, and the sex offspring ratio. As the animal model, we employ the layer strain of the Japanese Quail (Coturnix japonica) since they produce continuous eggs each day and easy to handle. The Japanese quail pairs were housed for seven days prior to the start of egg collection. These eggs were nurtured for up to three weeks after hatching until the sexing could be determined. When compared to a pair of three females, the egg production of a single pair was much higher when alternative pattern schemes were used. However, the mass of their typical eggs is remarkably similar. The male to female chick offspring sex ratio regularly showed to be 1:1 or equal. This finding could serve as the foundation for further research into the impact of partner pairing on another avian layer strain.
