Effect of time of oviposition on egg quality characteristics in cages and in a litter housing system
Original language description
Two experiments were carried out to investigate the effect of the time of oviposition on egg quality characteristics in two different housing systém (cages vs. litter). ISA brown hens from 20 to 64 weeks of age were housed in battery cages (550cm2/hen, 19 526 laying hens in the house) and on deep litter (7 hen/m2, 4 652 laying hens in the house). In both houses, eggs were collected daily at three oviposition times 06:00, 10:00 and 14:00 h. Every four weeks, 90 eggs for each house (30 eggs for each oviposition time) were used for egg quality assessment. The results indicated that in cages the highest percentages (P≤0.001) of normal (74.47%), non-standard (0.85%) and cracked (1.80%) eggs were laid in the early morning (06:00h). On deep litter, however, the highest percentages (P≤0.05) of normal sound eggs were produced at 10:00 h (35.43%). In the cage systém, the heaviest eggs (63.01 g) were laid in the early morning (06:00 h) and the highest shell percentage (10.33%) was in
