Best Basis of Selection for Carcass Quality Traits
The best basis of selection for estimation of carcass quality is:
- Sib selection — Correct Answer
- Individual selection
- Pedigree selection
- Progeny testing
Explanation:
Correct Answer: Sib selection
Sib selection is the best basis for carcass quality traits because the animal must be slaughtered to assess carcass quality, making direct individual selection impossible for breeding candidates.
How Sib Selection Works for Carcass Traits
- Siblings (sibs) of the candidate animal are slaughtered for carcass evaluation.
- The candidate animal is kept alive and selected/culled based on the sibs' carcass performance.
- This is a form of family selection (unit of selection = family mean).
Best Selection Method by Trait Type
| Trait Type | Best Method |
|---|---|
| Sex-limited traits (milk, egg) | Progeny testing |
| Carcass / slaughter traits | Sib selection |
| High h² traits | Individual selection |
| Low h² traits | Progeny testing / Family selection |
