Özet

In this study, 3484 milk yield records (1520 first, 1206 second and 758 third lactations) obtained from 1816 cows born between 1990 and 1997 in the Holstein-Friesian herd of Ceylanpinar State Farm were used to estimate the heritabilities, and genetic and phenotypic correlations between lactation milk yields using an individual animal model and the restricted maximum likelihood (REML) method.
