Are you looking to apply these parameters to a or focusing on a particular goal like meat yield versus wool quality ?
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" Genetic Parameters for Sheep Production Traits
This is crucial for "ewe productivity" traits. If a ewe performs well in her first lambing season (e.g., weaning a heavy lamb), repeatability tells us how likely she is to repeat 그 performance next year. High repeatability allows producers to cull underperforming animals early with confidence. Why This Matters for Your Flock Are you looking to apply these parameters to
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 weaning a heavy lamb)
Traits rarely move in isolation. When you select for one, you often get a change in another—sometimes for the better, sometimes not.
