The effect of oviposition time and genotype on egg quality characteristics in egg type hens

Popis výsledku v původním jazyce

In the experiment with three strains of Dominant genotype the effect of oviposition on egg quality characteristics was investigated. Laying hens of the Blue strain (group 1), Plymouth Rock (group 2) and their cross F1 (group 3) from age 20 to 64 weeks were housed on litter (9 birds per m2). The collection time was at 6.00, 10.00 and 14.00 h. Eggs were gathered in 28 days interval, every two days all produced eggs (total 720 eggs). The time of oviposition was influenced by genotype. The highest number ofeggs was collected at 6.00 in Plymouth Rock strain (53.5 %) and the lowest in the Blue strain at 14.00 (11.1 %). There were interactions between the time of oviposition and genotype in egg weight. Eggs laid in the morning at 6.00 were significantly heavier (60.5 g, 64.9 g and 62.1) in comparison with eggs laid in the afternoon (59.3 g, 62.4 g and 62.7 g). The heaviest eggs were produced by Plymouth Rock strain. Significant interactions were in egg shell weight when the heaviest egg shel
