Genetic and phenotypic parameters for type and production in Guernsey dairy cows.

Journal of dairy science - 1 Apr 1992

Harris B L, Freeman A E, Metzger E

Abstract excerpt

Heritabilities; genetic and phenotypic correlations for milk, fat, and protein production; and linear type traits were estimated from a sire model including sire relationships using multiple-trait REML. For the milk production traits, 68,109 first parity records were analyzed. Heritabilities ranged from .31 to .37, genetic correlations between the milk production traits ranged from .80 to .92, and phenotypic...
