The present study was designed to observe the oestrus responses in the indigenous ewe induced by cloprostenolsodium manufactured by two different companies (Ovuprost®, BOMAC, Newzealandand Prostenol®, Techno, Bangladesh). Twelve local ewes were divided into 3 groups (n= 8). The ewes in Group I and II were induced by intramuscular injectionof 100 μg (0.4 ml) of cloprostenol sodium (Ovuprost® and Prostenol®), respectively. The 2nd injection in each groupwas given at 9 days apart. The ewes in Group III were kept as control for observing natural oestrus characteristics andcomparing the responses with induced oestrus. Hundred and 75% ewes showed oestrus following 2nd injection ofOvuprost® and Prostenol®, respectively. The average time of onset of oestrus following 1st and 2nd injection of Ovuprost®and Prostenol® were 50.5 ± 3.5 vs 48.0 ± 0.0 h and 49.9 ± 1.9 vs 49.5 ± 1.7 h, respectively. There was no significantdifference between the two types of cloprostenol sodium group on the onset of oestrus. The average duration of oestruswas 27.5 ± 0.7 vs 27.5 ± 0.0 h and 25.9 ± 3.3 vs 24.2 ± 0.3 h in Ovuprost® and Prostenol® treated ewes, respectively. For natural oestrus, the duration of oestrus was 25.2 ± 3.3 h. There was no significant difference among the cloprostenolsodium produced by two different companies and natural oestrous ewes on the duration of oestrus. The higher percentagesof cornified cells were present in induced oestrus (90 and 85%) compared with natural oestrus (80%), although therewas no significant difference among them. The pregnancy rates were 75, 66.7 and 100% in Ovuprost®, Prostenol® andnatural oestrous ewes, respectively. The above results indicate the suitability of using cloprostenol sodium for synchronizationof oestrus in indigenous ewes in Bangladesh.
