Parameters For Sheep Production Traits | Genetic

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.

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

Traits like carcass lean meat yield and fiber diameter. You can make rapid progress just by selecting the best-performing individuals. Without knowing these parameters, a producer might spend

Selecting for higher yearling weight usually leads to higher birth weights. Heritability measures how much of the variation in

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.
