Understanding the genetic parameters of sheep is the backbone of any successful breeding program. It allows producers to move beyond guesswork and use data to predict how traits like growth, wool quality, and fertility will pass from one generation to the next. 1. Heritability ( h2h squared ): The "Pass-on" Rate
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 Genetic Parameters for Sheep Production Traits
Are you looking to apply these parameters to a or focusing on a particular goal like meat yield versus wool quality ? Understanding the genetic parameters of sheep is the
Growth rates and weaning weights. These respond well to selection but are influenced by the mother’s milk production. Heritability ( h2h squared ): The "Pass-on" Rate
Traits rarely move in isolation. When you select for one, you often get a change in another—sometimes for the better, sometimes not.
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
Heritability measures how much of the variation in a trait is due to genetics rather than environment (feed, weather, management).
