The effect of age of Japanese quails on certain egg quality traits and their relationships

Popis výsledku v původním jazyce

The effect of age on egg quality traits of Japanese quails (Coturnix coturnix japonica) were investigated. One hundred female quails were used in the study. The quails were placed in wire cages (3 females per cage) and were fed a mixture with 11.2 MJ MEand 19.7% of crude protein throughout the experiment. Feed and water were given ad libitum. Eggs were collected during 2 consecutive days during 4-week periods when the quails were from 9 to 49 weeks of age. A total of 2,060 eggs were examined. Egg quality traits were significantly affected by the age of quails with the exception of egg shape index and yolk colour. A rapid increase of the egg weight was found at the beginning of laying, highest weight (13.02 g) in 25th week of age, with subsequent gradual decrease in egg weight until the end of the laying period in 49 weeks of age. Despite frequent fluctuations, the albumen index, albumen weight, albumen proportion, Haugh units score, eggshell weight and eggshell strength decreased with
