The present study was aimed to evaluate the efficacy of estrus response in synchronized does using intravaginal sponges containing 350 mg progesterone (AVIKESIL-S) in situ for 11 days, 125 µg Cloprostenol, on day 10 and PMSG at two does of 200 IU (Group I) or 400 IU (Group II) on day 11 at the time of sponge removal, in non-descript does under field conditions. The percentage of estrous response and duration of estrus were observed to be 70, 100 and 100; 40.93 ± 1.49, 42.20 ± 1.32 and 49.50 ± 0.94 in control, Group I and Group II respectively. Pregnancy verification was done 40 to 45 days post mating by ultrasound examination and the conception rate in control, Group I and Group II was 52.40, 63.33 and 66.67 respectively. Follicular study, pre and post treatment of PMSG in the treatment groups indicated an increase in daily growth rate of follicles from 0.05 to 0.09 mm with the increase in dose of PMSG from 100 IU to 400 IU.
