Estimated Breeding Values (EBVs) and Indexes for Terminal Sire breeds have been updated. Signet’s new monthly, mixed breed analysis increases the commercial focus of existing traits and introduces a series of new EBVs.
Key Changes
Rebasing – EBVs and indexes have been rebased and are expressed relative to the average animal in 2010.
Weight adjusted traits – Please note that carcase traits are now weight adjusted. This means that EBVs are a better prediction of carcase composition at a fixed weight. Example: A ram with a muscle depth EBV of +2mm is estimated to produce lambs with loin depths 1mm deeper at a fixed weight than a ram with an EBV of 0.
Top 50% | Top 25% | Top 10% | |
Litter Size Born EBV | 0.01 | 0.04 | 0.07 |
Maternal Ability EBV | 0.20 | 0.42 | 0.61 |
Eight Week Weight EBV | 0.93 | 1.56 | 2.12 |
Scan Weight EBV | 2.34 | 4.05 | 5.58 |
Muscle Depth EBV | 0.16 | 0.67 | 1.13 |
Fat Depth EBV | -0.12 | 0.10 | 0.29 |
Gigot EBV | 0.02 | 0.91 | 1.71 |
Terminal Index | 149 | 188 | 223 |
Maternal Index | 139 | 171 | 199 |
- Litter Size Born (%) – EBV for female prolificacy.
- Maternal Ability (kg) – EBV for maternal care, particularly milkiness.
- Eight Week Weight (kg) – EBV for growth to eight weeks of age.
- Scan Weight (kg) – EBV for growth to scanning.
- Muscle Depth (mm) – EBV for muscling across the loin at a fixed weight.
- Fat Depth (mm) – EBV for fatness across the loin at a fixed weight.
- Gigot Muscularity (mm) – EBV for width of gigot at a fixed weight.
- Terminal Index – Superior breeding potential for growth and carcase characteristics.
- Maternal Index – Superior breeding potential to produce productive female replacements.
