Title: Traits influencing the hatching performance of Japanese quail eggs
Abstract: Abstract 1. Japanese quail eggs from moderately heavier sires showed superior fertility; while fertile eggs from moderately heavier dams hatched slightly better than the eggs from lighter dams. 2. Higher rates of fertility and hatchability of Japanese quail eggs were observed from parents of 10 to 19 weeks of age, with peak fertility and hatchability at 14 and 12 weeks of age, respectively. 3. Sex ratios of 1:2 to 1:5 gave comparable fertility and hatchability results. 4. The hatching performance of quail eggs from cage and deep litter reared breeders was comparable. 5. Fertility and hatchability were directly proportional to the egg weight. 6. Quail egg shell colour, tints and blotches were found to influence hatching performance. 7. Storing quail eggs at 16 ± 2°C and 75 ± 5% relative humidity for more than 4 d reduced hatchability. 8. Hatchability of eggs stored at room temperature was improved if they were sealed in polyethylene bags. 9. Provision of light during the first 14 d of incubation resulted in a photo‐acceleration of about 3.2 h.
