Influence of egg storage time and preincubation warming profile on embryonic development, hatchability, and chick quality.
When eggs are stored beyond 7 d, hatchability and chick quality decrease. The cause of the negative effects of prolonged egg storage is not clear. The negative effects may be caused by a decrease in embryo viability due to an increase in cell death. The optimal time and curve of preincubation warming (the preincubation warming profile) may be different for eggs stored over short and long period...
متن کاملInfluence of air composition during egg storage on egg characteristics, embryonic development, hatchability, and chick quality.
Egg storage beyond 7 d is associated with an increase in incubation duration and a decrease in hatchability and chick quality. Negative effects of prolonged egg storage may be caused by changes in the embryo, by changes in egg characteristics, or by both. An adjustment in storage air composition may reduce negative effects of prolonged egg storage because it may prevent changes in the embryo an...
متن کاملEffects of Egg Storage Material and Storage Period on Hatchability in Japanese Quail
The present study aimed to determine the effects of different storage materials and storage period on some hatchability traits of Japanese quail (Coturnix coturnix japonica) eggs. A total of 32 male and 102 female quail (twelve weeks of ages) were housed in multiple-bird cages. Eggs laid were divided into three groups with respect to the period of storage (I = 1, 2 and 3 days, II = 6, 7 and 8 d...
متن کاملThe effects of oviposition time on egg weight loss during storage and incubation, fertility, and hatchability of broiler hatching eggs.
An experiment was conducted to determine the effect of time of oviposition, generally representing different positions in the normal egg laying sequence, on egg weight loss during storage and incubation, and on fertility and fertile hatchability of eggs from mid-lay (42 wk) and old (67 wk) broiler breeders. A total of 1,800 eggs (900 eggs per flock age) were collected during 10 consecutive days...
متن کاملInfluence of Preincubation Egg Storage Duration on Egg Quality, Hatchability, Embryonic Mortality and Viability of Dandarawi Chicks
The aim of this study was to identify the optimal storage duration of incubated eggs of Dandarawi hens on embryonic mortality, hatchability, one-day chick weight and viability of chicks at 14 days of age. Eggs were collected 4 times daily for 15 consecutive days and stored at 16°C and 70% RH until sorted into treatments and then were incubated for 21 d under standard incubation conditions. The ...
