Reproductive traits like twinning rates or lamb survival. Because these are heavily influenced by environment/management, progress through breeding is slow. 2. Genetic Correlations: The "Package Deal"
Breeders use "Selection Indices" to balance these correlations, ensuring they don't accidentally compromise animal health or product quality while chasing growth. 3. Repeatability: Consistency Over Time
Growth rates and weaning weights. These respond well to selection but are influenced by the mother’s milk production.
Heritability measures how much of the variation in a trait is due to genetics rather than environment (feed, weather, management).
Are you looking to apply these parameters to a or focusing on a particular goal like meat yield versus wool quality ?
Enhance the overall "efficiency" of the flock—producing more output with the same input.
