Effect of genotype, age of hens and K/k allele on eggshell quality
Original language description
We assessed the influence of the particular genotype, age of layers, feather growth-rate gene, and their mutual interactions on selected indicators of eggshell quality in six groups of hens of the laying type Dominant (K - slow-feathering; k - fast-feathering. Eggshell quality was examined at the layers' age of 27, 35 and 56 weeks. The average egg weight was influenced statistically significantly by the age of hens, their genotype, feather growth-rate gene, and the relationship between the age and genotype. The age of hens, genotype, and the interaction of these two factors affected the egg shape index, as did the incidence of the feather growth-rate gene within the population. The age, genotype and the feather growth-rate gene incidence within the population also significantly affected the eggshell quality indicators. In the eggshell to egg ratio, eggshell thickness and strength, an interaction was determined between the age of hens and their particular genotype.
