Differences in oviposition and egg quality of various genotypes of laying hens

Popis výsledku v původním jazyce

The aim of the present study was to evaluate differences in egg production traits in six laying hen genotypes (the brown egg hens: Bovans Brown, Bovans Sperwer and ISA Sussex, the white egg hen Dekalb White and the laying hens with tinted shells Moravia Barred and Moravia BSL), and the interactions of genotype and oviposition on egg quality. The genotype affected the rate of lay, the mean sequence length and the time of oviposition. Brown egg genotypes laid eggs approximately 1 h earlier than white egg genotypes and approximately 2 h earlier than tinted-egg genotypes. Egg shell strength was the lowest in tinted egg genotypes and declined with the time of oviposition. Egg shell percentage and thickness were affected by interaction of the genotype and oviposition. None of the effects affected egg weight, however, a proportion of the egg components was significantly influenced by the interaction of genotype and oviposition. The data of the present study confirmed that the differences in the egg product
