Genetic Parameters For Sheep Production Traits (2024)

Traits rarely move in isolation. When you select for one, you often get a change in another—sometimes for the better, sometimes not.

In some breeds, selecting heavily for increased fleece weight can lead to a slight decrease in fiber fineness. Genetic Parameters for Sheep Production Traits

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" Traits rarely move in isolation

Enhance the overall "efficiency" of the flock—producing more output with the same input. Reproductive traits like twinning rates or lamb survival

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.
