The influence of biostimulation in combination with cloprostenol administration on estrus synchronization was studied. Twelve matured pre-partum ewes, weighing between 21 and 31 kg and 1 – 2 years of age were used for this study. The animals were assigned to four treatment groups (A, B, C and D) each consisting of three (n = 3) animals. Estrus manifestations were seen in group A, B, C and D as 100, 66.7, 66.7 and 0% respectively. The time to onset of estrus for groups A, B, C and D were 36.33 ± 8.32, 26.23 ± 2.81, 23.14 ± 0.14 and 0.00 ± 0.00 h respectively. The duration of estrus was 33.30 ± 12.60, 15.67 ± 13.58 and 0.00 ± 0.00 h respectively. Percentage synchrony was highest in group A, with all the animals being synchronized after the second dose of cloprostenol were administered. In groups B (single dose of cloprostenol with introduction of a ram) and C (double doses of cloprostenol without introduction of ram) percentage synchrony were same. Bio stimulation had a synergistic effect on cloprostenol and their combination will reduce cost of synchronization and is therefore recommended for synchronization programs.
