In this study the parameters including effect of sire, parity, effect of season and calving year were under the study. While the heritability and repeatability was analyzed with the method of data analysis. In current study result for milk yield showed that higher milk yield and lactation length were observed in spring season as compared to other seasons. The results of heritability and repeatability for milk yield, lactation length and dry period were low, medium to high.
