- Abstract
A total of 1385 lactation records of Tharparkar cattle collected from LRS Chandan, Jaisalmer spreading over a period of 33 years were utilized to assess the effects of period and season of birth/calving on age at first calving, calving interval and service period and also studied effect of parity on calving interval and service period. The least-squares means were 1821.86 ± 37.022 days, 414.16 ± 5.314 days and 122.04 ± 4.264 days, respectively for the above mentioned traits. A mixed model least-squares analysis showed significant effect of sire and period of calving on all the traits. Effect of parity was significant on all traits. Season of calving did not affect all reproductive traits.
