Interaction between oviposition time, age, and enviromental temperature and egg quality traits in laying hens and broiler breeders

Popis výsledku v původním jazyce

An experiment with laying hens and broiler breeders of two ages (young 22 vs. 36 weeks, old 83 vs. 64 weeks) and at 20 and 28 °C was carried out to evaluate the interactions between oviposition time (7:30; 11:30 and 15:30 h) and egg quality. The significant interaction (P?0.011) was determined in oviposition time. The highest number of eggs was laid by young laying hens kept in temperature 20 °C at 7:30 h (25.8 %) and the lowest in young layers in temperature 20 °C and at 15:30 h (3.7 %). Time of oviposition was delayed by age and higher temperature. Egg weight was significantly influenced by production type (P?0.001, 60.5 vs. 68.1 g), age (P?0.001, 59.4 vs. 69.3 g) oviposition ((P?0.001, 66.5 g; 63.7 g; 62.8 g) and temperature (P?0.022, 65.1 vs. 63.6g). The significant three-way interaction of age, oviposition and temperature in Haugh unit score (P ?0.013) and four-way interaction of production type, age, oviposition and temperature (P?0.05) in specific gravity, show that valuable ch
