Short communication: variance estimates among herds stratified by individual herd heritability.

Journal of dairy science - 1 Apr 2008

Abstract excerpt

The objectives of this study were to compare (co)variance parameter estimates among subsets of data that were pooled from herds with high, medium, or low individual herd heritability estimates and to compare individual herd heritability estimates to REML heritability estimates for pooled data sets. A regression model was applied to milk yield, fat yield, protein yield, and somatic cell score (SCS) records from...
