Abstract:
1. The relationships between egg weight or age of breeder quails (Coturnix coturnix japonica) and 1-d-old chick weight were determined. 2. Significant correlations were found between egg weight and chick weight (R2 = 0.32) and age and chick weight (R2 = 0.86). Thus, hatching weight was influenced more by the age of breeder quails than by egg weight as such. 3. Chick weight was accurately predicted by the use of age as a single independent variable; egg weight did not explain any further variation.
