| R2 adjust | 0.01 | 0.08 | 0.06 | 0.13 | 0.04 |
aNo significant differences exist between means (P > 0.05).
Abbreviation: CV, coefficient of variation.
Results are expressed as mean ± SD.
Egg weight loss = (initial egg weight–egg weight during transfer)/initial egg weight × 100.
Chick yield (%) = (chick weight at the day of hatch/initial egg weight) × 100.
