Data representing 114 Deoni cows from 211 total records of lactation over a 30 years period were analysed to determine the effect of Age at first calving, season of calving and period of calving on production traits. The overall least squares means of age at first calving, service period, gestation period and inter calving period were 1659.15 ±35.77,203.73 ±12.47, 278.80 ± 0.44 and 457.06 ± 15.47, days respectively. The age at first calving had non significant effect on service period, gestation period and inter calving period. All sources of variation for season of calving on reproduction traits were non significant. The period of calving had significant effect on age at first calving and gestation period, whereas its effect on service period and inter calving period was nonsignificant.
