ABSTRACT:
The objective of the present study is to determine the physical characteristics and incubation parameters of eggs of three strains of quail (Coturnix Japonica, Coturnix Coturnix and their crossing (Japonica X Coturnix) of white color. Five hundred eggs (500) of each strain were divided into five blocks of one hundred (100) eggs randomly and were the subject of our experimentation. The weight of the egg and the shape index of the three strains are similar (p> 0.1). The thickness of the cross Japonica X Coturnix is important (p <0.04) than that of the other two strains. The Haugh unit is dominant (p <0.03) for the Japonica strain. The Coturnix strain outclasses the other strains for the height of the yolk (8.30mm, p <0.01) and for the weight of the white (5.26g p <0.04). The weight of the yolk with 4.26 g and a yellow / white ratio of 0.96, marks a dominance of the cross strain Japonica X Coturnix. The shell / live weight ratio is similar for the three strains. The fertility of the coturnix strain is dominant (91%) (p <0.02) and the cross strain ensures an optimal hatching rate of (63%) (p <0.01). The embryonic mortality rate is minimal (18%) for the coturnix strain while it remains high for the other strains (approximately 36%).
