Egg morphologic and biochemical composition in quails divergent in egg production

Abstract

Egg quality maintaining with high egg production is actual problem. This research task has been to analyze quail egg morphologic and biochemical composition in Omskaya quail breed in groups that are divergent in egg production (±1.5 ÷2σ from average). Eggs of quails with high egg production intensity had greater egg shell mass (by 0.19 g, P<0.001) and less white mass (by 0.47 g, P<0.05). Outer layers proportion has changed with egg production increasing. Protein content in quail egg white and yolk have been 10.64 and 16.71% in quails with high egg production that is less than in quails with low egg production by 0.1 and 0.23% respectively.
