Abstract

A total of twenty Gir cows with reproductive disorders were selected and treated (Group I) with single dose of prostaglandin (cloprostenol) while animals which did not respond (Group II) to first injection of prostaglandin were subjected to second injection of prostaglandin eleven days after first treatment. A total of eight animals (40%) responded to first dose of PGF2α, while ten animals (83%) responded to second dose of PGF2. The mean time required for induction of heat in first and second group was 70.24 ±1.44 hrs and 56.86 ±1.96, respectively. The mean duration of estrus proper in first group was 19.18± 0.69 hrs, while in second group it was 16.13±0.42 hrs. The conception rate of 43.05% was observed for first group and 49% for animal treated with second dose of PGF2α. In conclusion, administration of PGF2α at eleven days interval causes faster heat induction and better conception rate.
