Abstract: In the present study, 91 white Sindhi cows were maintained at the Livestock Research Station, Beechwal, Bikaner for 11 years, from 2006 to 2016. Based on the data, we assessed the performance traits of white Sindhi cattle and examined the effect of genetic factors, such as sire group, and non-genetic factors, such as calving season and period. In general, least squares means for lactation milk yield of first parity, lactation length of first parity and dry period of first parity were found to be 1833 kg, 283.7 days, and 148.1 days. On first parity production traits, sire was shown to have a significant effect. Lactation length of first parity was significantly influenced by the period of calving, while season of calving did not have a significant impact on first parity production traits. There was a significant impact of the age at first calving on lactation milk yield of first parity and lactation length of first parity.
