Best Method of Sire Evaluation
Most recent & best method of sire evaluation is-
- BLUP — Correct Answer
- Contemporary index
- Equi-parent index
- None
Explanation:
Correct Answer: BLUP
BLUP (Best Linear Unbiased Prediction), developed by C.R. Henderson, is the most recent, advanced, and statistically accurate method globally used for sire evaluation and estimation of breeding values.
Methods of Sire Evaluation — Comparison
| Method | Features | Limitation |
|---|---|---|
| BLUP | Most powerful; corrects for fixed effects (herd, season, year); uses full relationship matrix; simultaneous evaluation of all animals | Computationally intensive; requires pedigree data |
| Contemporary index | Compares daughters with contemporaries in the same herd-season group | Does not account for genetic relationships |
| Equi-parent index | Simple early index method | Does not correct for environmental differences |
| Sire index | Index of genetic worth of a sire based on daughters | Basic version; superseded by BLUP |
BLUP in Nucleus Breeding
- BLUP is the most powerful method of indexing sires in both CNBS and ONBS.
- It provides EBV (Estimated Breeding Value) for each animal.
- BLUP combined with MOET in ONBS gives maximum genetic gain per year.
