ABSTRACT
ABSTRACT This study was carried out to investigate selected traits of hatched and unhatched eggs and chick growth performance of yellow Japanese quails (Coturnix japonica). Eggshell temperature at the time of transfer to the hatcher was higher in hatched eggs (38.09oC) than in unhatched eggs (37.43oC) (p=0.000), lower in eggs with in early embryonic mortality (37.39oC) than those with late embryonic mortality (38.13oC) (p=0.000), and higher in eggs with female chicks (38.14oC) than those with male chicks (37.95oC). Lower eggshell, yolk, and albumen weights were determined in eggs with embryonic mortality of 17-18 days (0.58 g, 3.13 g and 4.96 g) compared with those with 10-16 days (0.67 g, 3.55 g and 5.58 g) and embryonic mortality of 1-9 days (0.75 g, 3.95 g and 6.19 g) (p=0.000). Lower egg weight loss was obtained in eggs with embryonic mortality (13.85%) of 1-9 days than those with embryonic mortality of 17-18 days (26.48%) (p=0.001). Females were heavier at chick weight (8.98 g vs. 8.63 g; p=0.033) and at 4 (231.81 g vs. 211.43 g; p 0.000) and 5(260.69 g vs. 231.87 g; p 0.000) weeks of age than males, and had longer left shanks (34.39 mm vs. 33.61 mm; p=0.004).
