The effect of genotype, housing system and egg collection time on egg quality in egg type hens.
Original language description
The effect of egg collection time, genotype and housing system on egg quality characteristics was evaluated in an experiment with laying hens of ISA Brown, Hisex Brown and Moravia housed on litter and in conventional cages. The experiment was conducted from 20 to 64 weeks of age. Eggs were collected and recorded daily at 6:00, 10:00 and 14:00 h. Once every four weeks, two days in row, all eggs laid from each pen or cage at each oviposition time were used for egg quality analyses (total 1694 eggs). Egg collection time was dependent on genotype. Significantly more eggs were laid at 6:00h by ISA Brown while Moravia laid eggs mainly at 10:00 and 14:00 h. Housing on litter postponed time of oviposition. The highest egg weight (62.09 g) was recorded in HisexBrown genotype placed in cages and at 6.00 h. Interactions of all factors were determined also in Haugh Units (P ≤ 0.041). Eggshell strength was affected by housing system, genotype and egg collection time (P ≤ 0.049). It was
