The present study was conducted to evaluate reproductive performance of Kenguri ewes after breeding with NARI- Suwarna frozen thawed semen. Oestrous cycle of Kenguri ewes (n=10 + 10) was synchronized by injecting PGF2α. All the ewes were inseminated twice with gap of 12 hours using frozen thawed semen dose of NARI Suwarna (Deccani + Garole) strain. Pregnancy diagnosis was initiated on days 24, 34 and 44 of post artificial insemination using trans-abdominal ultrasonography. Based on the present findings it can be concluded that the estrous cycle may be synchronized by injecting PGF2α. on days 0 and 9 in or day 0 and day 11 with 100 % estrus induction rate in Kenguri ewes. The incidence of false positive pregnancy diagnosis was higher on days 24 and 34 by using transabdominal ultrasonography. The climate temperature, heat stress may be one of the reasons for the early embryonic mortality in Kenguri ewes. The lambing rate by inseminating the Kenguri ewes with frozen thawed semen was lowest (10%) in trans-cervical method. None of the Kenguri ewe from both the treatment and control groups showed any disease or accident during gestation and lambing after using NARI Suwarna frozen thawed semen. The sex of both the lambs was female with body weight ranging from 2.35 to 2.60 with gestation period range of 147 to 151 days.
