Genetic Parameters For Sheep Production Traits < TOP >

Growth rates and weaning weights. These respond well to selection but are influenced by the mother’s milk production.

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

In some breeds, selecting heavily for increased fleece weight can lead to a slight decrease in fiber fineness. Growth rates and weaning weights

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

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.
