A study was conducted on the performance of Tharparkar cattle maintained at Livestock Research Station (LRS), Beechwal, Bikaner. The performance records of first lactation production and reproduction traits of Tharparkar cows were collected from the LRS, Beechwal spread over a period of eight years (2012 to 2020). The overall least-squares means for first lactation 305-days milk yields (FL305DMY), first lactation length(FLL), first dry period (FDP) and age at first calving (AFC) were 2003.52 ± 71.83kg, 296.76 ± 7.25 days, 119.51 ± 7.44days and 1417.88 ± 20.59days, respectively. The non-significant effect of period of birth/calving was found on all first lactation traits under study except age at first calving. Season of birth/calving did not influence these traits in the present study. The random effect of sire was found highly significant (P< 0.01) on AFC and non-significant on all the production traits. The regression of traits on age at first calving was also found non-significant. The study concluded that the performance of Tharparkar cattle for first lactation traits was not influenced by environmental factors; it may be adaptation of this breed in arid region of Rajasthan.
