- Genetic Variation
- BLUP Models
- Environmental Uniformity
- Accurate Measurement
- a Manage animals to keep environmental effects as similar as possible across the population.
- b Variability of BV for a trait in the population. The greater the genetic variation, the greater the difference between superior and inferior animals.
- c Reduce potential measurement error, use most precise measurement as possible.
- d Measure of the strength of the relationship between repeated records for a trait in a population.
- e Best Linear Unbiased Prediction. Enables large scale genetic evaluation.
5 Multiple Choice Questions
- Important for individual performance
- Nutrition, track conditions, illnesses
- Training, permanent injury, developmental programming.
- Lists of genetic predictions, accuracy values, and other information for sires within a breed.
- Genetic value as a parent. Indication of potential to contribute to offspring.
5 True/False Questions
Generation Interval → Multiple trait selection reduces selection intensity compared to selection for a single trait.
Replacement Rate → Traits for which individual animals have multiple performance records. (milk production, calf weaning weight)
Independent Culling Levels → Set a minimum performance level for each trait being considered. Cull any animal that does not meet the standard for every trait.
Trait Ratios → Calculated using covariance, a measure of how two traits or values vary together in a population.
Repeated Traits → Traits for which individual animals have multiple performance records. (milk production, calf weaning weight)
