Selecting for higher yearling weight usually leads to higher birth weights.
Enhance the overall "efficiency" of the flock—producing more output with the same input.
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
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
Traits rarely move in isolation. When you select for one, you often get a change in another—sometimes for the better, sometimes not.
Traits like carcass lean meat yield and fiber diameter. You can make rapid progress just by selecting the best-performing individuals.
Growth rates and weaning weights. These respond well to selection but are influenced by the mother’s milk production.
