영어 초록
The present study was designed to observe the oestrus responses in the indigenous ewe induced by cloprostenol sodium 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 injection of 100 μg (0.4 ml) of cloprostenol sodium (Ovuprost® and Prostenol®), respectively. The 2nd injection in each group was given at 9 days apart. The ewes in Group III were kept as control for observing natural oestrus characteristics and comparing the responses with induced oestrus. Hundred and 75% ewes showed oestrus following 2nd injection of Ovuprost® 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 significant difference between the two types of cloprostenol sodium group on the onset of oestrus. The average duration of oestrus was 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 cloprostenol sodium produced by two different companies and natural oestrous ewes on the duration of oestrus. The higher percentages of cornified cells were present in induced oestrus (90 and 85%) compared with natural oestrus (80%), although there was no significant difference among them. The pregnancy rates were 75, 66.7 and 100% in Ovuprost®, Prostenol® and natural oestrous ewes, respectively. The above results indicate the suitability of using cloprostenol sodium for synchronization of oestrus in indigenous ewes in Bangladesh.참고 자료
