Estimation of genetic parameters for test day records of dairy traits in the first three lactations.

Genetics, selection, evolution : GSE - 1 Jan 2000

Druet Tom, Jaffrézic Florence, Ducrocq Vincent

Abstract excerpt

Application of test-day models for the genetic evaluation of dairy populations requires the solution of large mixed model equations. The size of the (co)variance matrices required with such models can be reduced through the use of its first eigenvectors. Here, the first two eigenvectors of (co)variance matrices estimated for dairy traits in first lactation were used as covariables to jointly estimate genetic...
