Abstract

Unbiased estimates of sire and error variance are needed for estimation of heritability from half-sib groups.  With high speed electronic computers being available, the least squares procedure to estimate the sire and error variance may be preferable.  However, the computational difficulties of analysing records according to complex models have led many investigators to express records as deviation from some function of contemporary average.  These deviated records are then analysed according to simple models.  In this paper we have tried to estimate heritability using records deviated from herd average and herdmate average.
