Estimation of (co)variance components for Jersey type traits using a repeatability model.

Journal of dairy science - 1 Aug 1997

Gengler N, Wiggans G R, Wright J R, Norman H D, Wolfe C W

Abstract excerpt

(Co)variance components for final score and 15 linear types traits of Jersey cows were estimated by multitrait REML using multiple diagonalization and a repeatability model with 34,999 records of 22,354 cows. Multiple diagonalization gave relative off-diagonals (ratio of squared off-diagonals to the product of diagonals) of < 0.1%. Heritabilities and repeatabilities, respectively, were estimated as 0.29 and 0.48...
