ABSTRACT

Age at 1st calving, lactation yield and lactation length are important characters in dairy cattle. Different methods such as ANOVA, ML, REML, MIVQUE are used to estimate variance components and in turn, heritability which is one of the most important genetic parameter for selection of sires for breeding purpose. In this paper, heritabilities of age at 1st calving, lactation yield and lactation length in Kankrej breed have been estimated using the above 4 methods and estimates so obtained are compared.
