“…The number of eggs laid at each collection time was influenced by genotype (Table 1), which coincides with findings of Lillpers and Wilhelmson (1993), Garces and Casey (2003) or Lewis et al (2004), who described differences in the mean oviposition time according to genotype. Plymouth Rock hens laid more eggs early in the morning (until 6:00) whereas in Blue strain and F1 genotypes the time of oviposition at 6:00 and 10:00 was similar.…”

“…Lewis et al (1995) revealed that the mean oviposition time for a brown egg hybrid was 1.2 to 1.4 h earlier than that of a white egg genotype. In the next paper Lewis et al (2004) recorded the time of oviposition in broiler breeder hens under an 8-16 h photoperiod. The mean oviposition time was delayed in a photoperiod up 14 h but it was similar for a 14 h and 16 h photoperiod.…”

ABSTRACT:In an experiment with three strains of Dominant genotype the effect of oviposition on egg quality characteristics was investigated. Laying hens of the Blue strain (group 1), Plymouth Rock (group 2) and their F1 cross (group 3) from 20 to 64 weeks of age were housed on litter (9 birds per m 2 ). The collection time was at 6.00, 10.00 and 14.00 h. Eggs were gathered in a 28-day interval, every two days all produced eggs (720 eggs in total). The time of oviposition was influenced by genotype. The highest number of eggs was collected in the Plymouth Rock strain at 6.00 (53.5%) and the lowest in the Blue strain at 14.00 (11.1%). There were interactions between the time of oviposition and genotype in egg weight. Eggs laid in the morning at 6.00 were significantly heavier (60.5 g, 64.9 g and 62.1 g) in comparison with eggs laid in the afternoon (59.3 g, 62.4 g and 62.7 g). The heaviest eggs were produced by the Plymouth Rock strain. Significant interactions were observed in eggshell weight when the heaviest eggshell was in afternoon eggs (5.6 g, 5.8 and 5.9 g) and F1 genotype. The egg shape index was also affected by the genotype and time of oviposition. Among the albumen quality characteristics only Haugh Units were influenced by genotype and significantly higher numbers were determined in the Plymouth Rock strain (85.0, 85.3 and 84.7). The genotype significantly affected also the yolk index which was the highest in F1 genotype (45.4%, 45.4% and 44.5%).

“…All these events are influenced by the age of bird, the strain, level of nutrition, and other environmental factors Gous 2006, 2007). Lewis et al (2004) reported that in commercial crossbred laying hens the mean oviposition time was by about 1 h earlier in comparison with broiler breeders. Zakaria et al (2005) reported that as a flock was ageing, the eggs were laid later in the day.…”

ABSTRACT:The aim of the study was to evaluate egg shell quality characteristics, mineral content in the egg shell, and serum mineral concentration during the egg formation process as influenced by oviposition time and ambient temperature at the beginning and end of the laying cycle in laying hens and broiler breeders. Egg shell quality deteriorated significantly at the higher temperature and was lower in broiler breeders than in laying hens. The Ca (P = 0.047) and P (P = 0.018) contents of the egg shell were significantly higher at the higher temperature. The highest (P = 0.028) shell Ca content (352 g/kg) was in eggs laid in the morning, but the highest P (P = 0.030; 1.43 g/kg) and Mg (P = 0.001; 3.88 g/kg) contents were in eggs laid in the afternoon. Broiler breeder egg shells contained significantly more P (P = 0.004) and Mg (P = 0.001) than did those from laying hens. Serum Ca and P levels remained constant throughout the day whereas serum Mg and Zn levels decreased, the rate of decrease in Zn content being the same in all treatments, but with the amounts being greater in laying hens than broiler breeders. The results demonstrate that shell quality characteristics are more severely affected by different factors implemented in this trial compared to the shell mineral composition and especially compared to the serum mineral content.

“…There are few published data about the time pattern of oviposition in broiler breeder hens. Recently, Lewis et al (2004) recorded the mean oviposition time for in-lay birds kept under different photoperiod conditions (8 h-16 h light) and revealed differences in oviposition time between Some researchers demonstrated a relationship between egg position in the sequence and hatchability of eggs from broiler breeder hens (Robinson et al, 1991a;Fasenko et al, 1992). However, Zakaria et al (2005Zakaria et al ( , 2009 reported no effect of oviposition time on hatchability of fertile eggs.…”

ABSTRACT:The aim of the study was to analyze the pattern of oviposition time in laying sequences in broiler breeder hens and to determine a relationship between egg position in the sequence and egg quality. The sequences were described using mean oviposition time (hour) within a sequence, mean lag of oviposition time between successive ovipositions, and mean and cumulative lag of oviposition for a sequence. Egg weight, percentage of egg components and shape index were determined for successive eggs in a sequence. The 2-, 3-, 4-, 5-to 6-and 7-to 9-egg sequences were considered. The light/dark regime was 16 h/8 h (05:00 a.m. to 09:00 p.m.). Hens laid the first egg in a sequence about 3.5 h after the beginning of the photoperiod. With increasing sequence length, the first egg was laid sooner after the beginning of the photoperiod and the intervals between successive ovipositions shortened. This suggests that when planning the frequency of egg collection in a flock of broiler breeder hens, one should account for changes in the egg sequence length during the production period. No significant relationship between egg position in the sequence and quality of egg components was observed.
