Abstract
1. Specific values of constants needed to estimate fresh weight (K w) and volume (K v) of Greater Rhea eggs were obtained.
2. The average value for the weight coefficient (K w) was 0·57, whereas that for volume (K v) was 0·51. Accuracy of results obtained with these values was ±2·1% and ±3·5%, respectively.
3. The fresh weight and volume of Greater Rhea eggs can be easily estimated by means of these specific coefficients when those measurements cannot be taken directly.
