The study was envisaged to evaluate therapeutic effect of PGF2α analogue on the incidence of post-partum complications, uterine involution and fertility in crossbred cows. A total of 21 apparently healthy cows, immediately after normal calving were randomly allotted to two groups. Animals in group I were administered with 500 μg of cloprostenol sodium (synthetic PGF2α) intramuscularly within two hours of calving, whereas those in group II were left untreated. Incidence of post-partum complications, number of days required for complete uterine involution and fertility indices were recorded in all the animals. Incidence of post-partum complications was higher in group II than group I. Number of days taken for complete uterine involution, as assessed by rectal examination was significantly (p<0.05) shorter in group I (28.33 ± 1.67 days) than group II (32.22 ± 1.21 days). The time interval from calving to first observed oestrus and calving to first AI interval did not differ significantly (p>0.05) between groups (26.11 ± 2.87 and 53.89 ± 2.91 vs 32.22 ± 1.21 and 55.33 ± 4.45 days, respectively in group I and II, respectively). While, calving to conception interval did not differ significantly (p>0.05) between groups (69.14 ± 9.02 vs 74.40 ± 9.25 days), first AI and overall conception rate was higher in group I (44.44 and 77.78 per cent, respectively) than group II (11.11 and 55.56 per cent, respectively)
