Variance Components and Breeding Values of Birth Weight in Holstein Calves
Abstract
In this study, it was aimed that estimation of the variance components and Best Linear Unbiased Prediction (BLUP)
values of Holstein calves birth weight in Kocas State Farm, using Animal Model in MTDFREML package program. Pedigree
and birth weight records of the calves (n=1099) between the years of 1992-2001 were used as research material. Year, birth type,
sex and interaction of year - birth type were taken as fixed factors affecting the birth weight. Dam age was included into the
analyses as a covariate. Variance components were calculated by using six different models of Restricted Maximum Likelihood
(REML) technique. Heritability and standard error were found as 0.39±0.077. As a result, birth weight of Holstein calves reared
in Kocas State Farm can be increased through selection.
