Effect of time of oviposition on egg quality in egg and meat type hens
Popis výsledku v původním jazyce
Two experiments were carried out to investigate the effect of time of oviposition on egg quality characteristics in egg and meat type hens. In the experiment 1, egg type ISA Brown hens from 20 to 64 weeks of age were housed on litter (7 hen/m2) and in the experiment 2, meat type Ross 308 hens at the age from 23 to 55 weeks (5.5 hen/m2) were used. Eggs were collected daily at three-oviposition times 06:00, 10:00 and 14:00 h. Every four weeks, 90 eggs for each type (30 eggs for each oviposition time) wereused for egg quality assessment. In egg type, time of oviposition had no significant effect on egg weight and eggshell quality characteristics except shell thickness. Morning eggs had greater shell thickness (0.398 mm) than afternoon eggs (0.390 mm). Inmeat type, the significantly (P ≤ 0.05) heaviest eggs (64.17 g) were laid in the early morning (06:00 h) and the significantly (P ≤ 0.05) highest shell percentage (10.92%) was in eggs laid in the afternoon (14:00 h).
