Data on 197 breeding records of 60 indigenous (Non-descript) cows maintained at Livestock Development Research Centre Raroo, Muzaffarabad, Azad Kashmir, Pakistan from 1989-1998 were analyzed to evaluate their performance with respect to some economically important reproductive traits. The least squares mean for age at first calving in present study was 1632.65+54.52 days with a C.V 13.04%. The analysis of variance revealed a significant (P<0.05) effect of season and year of birth on age at first calving. The least squares mean for post partum oestrus interval was 145.42+98.72 days with a C.V 89.43%. The analysis of variance revealed a non-significant effect of season and year of calving on post partum oestrus interval. The least squares mean for service period was l67.82+95.99 days with a C.V 76.42%. There was a non-significant effect of season of calving on service period but the effect of year of calving was significant (P<0.01). The least squares mean for calving interval in present study was 471.26+89.34 days with a C.V 23.84%. There was a non-significant effect of season of calving on calving interval, whereas the effect of year of calving was significant (P<0.01). Parity had a non-significant effect on post-partum oestrus interval, service period and calving interval in this study.
