Changes in some egg quality parameters according to plumage colour in quails and their relationships

PDF

The effect of plumage colours of Japanese quails (Coturnix coturnix japonica) on some egg quality parameters and their relations amongst were studied in this study. A total of 144 hatching eggs which were obtained from middle-aged (13 week) quail breeders having two different (original and white) plumage colours (77 orginal and 77 white) were used in the experiment. Egg weight (EW), egg length (EL), egg width (EWd) and shape index (SI) were studied parameters for egg quality. Coefficient correlation and regretion were analyzed for relation among these parameters. In the study, from the eggs of quail with original and white plumage, average EW; 10.79 g and 9.54 g, EL; 31.59 mm and 31.57 mm, EWd; 25.85 mm and 24.68 mm, SI; 81.86 and 78.29 values were obtained respectively. EW, EWd and SI values were higher in quails with black feathers than those with white feathers (P < 0.05), but SI values were similar (P > 0.05) in both groups in the experiment. When the correlation coefficients were examined, it was found that the correlation coefficient between EW and SI were only significant in the birds with original plumage and between EW and SI in birds with white plumage (P < 0.05). From regression analysis, it was found that the EW values can be estimated more accurately by using the EL in original plumages and the EWd in quails with white-plumage. It is thought that carrying out more detailed and post-incubation studies will be beneficial for both academic and sectoral development.
