Genetic studies on production efficiency traits in Murrah buffaloes.

The article presents information on genetic studies about milk production efficiency traits in Murrah buffaloes. Various tangible factors on different traits under study were estimated using the least-squares and maximum likelihood computer program of Harvey using Henderson's method III. Estimates were categorized in terms of heritability and genotypic correlations. Findings revealed that first lactation peak yield persistency can be used as a selection criterion.
