From: Mapping of QTL affecting incidence of blood and meat inclusions in egg layers
Pop. | N | Trait | Scaling | Age of evaluation | Correction |
---|---|---|---|---|---|
F 2 | 1599 | Blood and meat spots (BMS F2) | Adjusted from number and type of spots | 35, 40, 50 weeks | Average of three sequential eggs, multiplied by 100. |
LB | 416 1 | Score | continuous scaling from 0 to 5 | 36, 40, 42 weeks | LN correction |
 |  | Group | count of spots = > high or low | 36, 40, 42 weeks | effect of hatch and tier of the battery |
 |  | Number of spots | absolute number of spots | 36, 40, 42 weeks | (number_corr+0,05)*100 |
 |  | Size of spots | continuous (in mm) | 36, 40, 42 weeks | (size_corr+0,1)*100 |
 |  | Combination | number * size | 36, 40, 42 weeks | (combination_corr+0,1)*100 |
Hy-Line | 290 | Blood spots (BL) | Semi-quantitative | early, late | The phenotypes were expressed as sire-daughter averages |
 |  | Meat spots (MS) | Semi-quantitative | early, late | The phenotypes were expressed as sire-daughter averages |
