The effect of eggshell thickness on hatchability of quail eggs
BACKGROUND AND AIM The aim of the successful incubation period is to achieve maximum health chicks in each batch. Therefore, all factors affecting incubation have to be investigated in detail. This study investigated the effect of eggshell thickness on hatchability of quail eggs. MATERIALS AND METHODS A total of 1415 eggs were collected from the same flock at the ages of 23 and 41 weeks. Two ...
متن کاملEggs weight of Japanese quail vs. eggs quality after storage time and hatchability results
The aim of the performed investigations was to compare eggs of Japanese quail layers of different weights with regard to their shape, selected traits of the content following various times of their storage as well as the results of hatchability and body weight of one-day old chicks. Hatching eggs were divided into four groups: group S – up to 10.50 g, group M – from 10.51 to 11.50 g, group L – ...
متن کاملEffect of Turning Duration of Incubated Eggs on Hatchability, Mbryonic Mortality and Chick’s Viability
The aim of this study was to identify the optimal turning duration of Dandarawi hen incubated eggs on embryo mortality, hatchability, one-day chick weight and viability of chicks at 14 days of age. Collected eggs from Dandarawi hens at 36 weeks of age were stored for 7-d at 16°C and 75% RH and then were incubated for 21-d under standard incubation conditions using different turning durations. E...
متن کاملEmbryonic Growth, Hatching Time and Hatchability Performance of Meat Breeder Eggs Incubated under Continuous Green Light
The effects of dark-control (D) and continuous green light (GL) exposure of incubated meat-type breeder eggs (Hybro) on embryonic growth from 5 to 15 days of age, hatching time, hatchability per cent and chick hatching weight were investigated in three consecutive experiments at 33, 38, and 41 weeks of age. A total of 798 eggs were used in this study. Eggs were set in an incubator on trays eith...
متن کاملAnalyzing of Quail Eggs Hatchability, Quality, Embryonic Mortality and Malpositions in Relation to Their Shell Colors
A total 2400 hatching eggs were obtained from Japanese quails breeders ranged from 100 to 150 days of age used to analyze the effect of shell color on fertility, hatchability, embryonic mortality and malposition as well as internal and external egg quality. Results revealed that shell color had significant effect on fertility and scientific hatchability while it doesn't affect commercial hatcha...
