Genetic Parameters For Sheep Production Traits -

Heritability measures how much of the variation in a trait is due to genetics rather than environment (feed, weather, management).

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

Without knowing these parameters, a producer might spend years trying to "breed" for a trait that is actually 90% determined by the quality of the pasture. By focusing on and using Estimated Breeding Values (EBVs) , you can: Increase the average weight of lambs at market. Improve the uniformity and micron of wool clips.
