Comparison of laying intensity and egg quality the effect of Japanese quails (Coturnix japonica) with different feather color

Popis výsledku v původním jazyce

The aim of the study was to evaluate the effect of genotype on laying intensity and egg quality in Japanese quails Coturnix japonica L. Four genotypes were different in plumage color, twelve quails of the same age of each genotype were included in the experiment, 48 birds in total. The observation lasted 90 days. Quails were housed in individual cages. Egg number was recorded daily, egg quality was done in two weeks intervals. Laying intensity was high in all genotypes (92.2-94.4%) without significant differences, however the highest laying intensity was in quails with aguti and mahogany types of plumage. Egg weight was significantly the highest in mahogany type (13.7 g, P&lt;0.05). Eggshell weight was significantly the lowest in quails white type plumage (P&lt;0.05), which was associated with the lowest strength of eggshell (P&gt;0.05). Albumen proportion was significantly the highest in mahogany type plumage (P&lt;0.05). On the other hand Haugh units were the highest in quails with aguti type plumage. Yolk weight was the highest in gold type and the lowest in mahogany type plumage (P&gt;0.05). Yolk colour was similar in all genotypes. The highest body weight was in mahogany type (303 g), the lowest in gold type quails (263 g).
