Age related changes in laying pattern and egg weight of different laying hen genotypes
Original language description
The aim of the study was to evaluate changes in laying patterns depending on the age of different genotypes of laying hens. In the experiment, six genotypes were evaluated (brown egg hens Bovans Brown, Bovans Sperwer and Isa Sussex, white egg hens Dekalb White, and laying hens with tinted shells Moravia Barred and Moravia BSL) in three periods during the laying cycle (the onset of lay between 20 and 26 weeks of age, the middle from 36 to 42 weeks of age and the end of lay between 64 and 70 weeks of age). A significant interaction between genotype and age was apparent in mean sequence length, length of the prime sequence, mean number of sequences and mean time of oviposition. The longest lag during the course of the experiment was with Moravia BSL, which was more than 3 h, the shortest lag was observed in Bovans Brown, which was less than 1 h. The mean time of oviposition was also affected by genotype. Bovans Brown laid their eggs approximately 3,5 h after the lights came on, whereas Moravia BSL laid
