Özet:

 

The study was aimed to identify the effective cervical ripening treatment to increase the pregnancy rates following transcervical artificial insemination (TC-AI) in indigenous ewes of Bangladesh. Three treatments schedules were compared, G1 (n = 6, control), G2 [n = 6, prostaglandin E1 (PGE1) as Misoprostol-Cytomis®] and G3 (n = 6, estrogen as Oestriol-Ovestin® + oxytocin as Linda-S® Vet). Ewes (n=18) were synchronized for estrus using two doses of 100 µg prostaglandin (PGF2α; Ovuprost®) 9 days apart. The cervical ripening treatments were administered just after the onset of estrus and left for 12 h before TC-AI. The cervical ripening was reflected with the depth of cervical penetration. The depth of cervical penetration in G1, G2 and G3 both before and after cervical ripening treatments were 0.33 ± 0.10 cm vs 0.43 ± 0.07 cm, 0.41 ± 0.09 cm vs 3.50 ± 0.26 cm and 0.43 ± 0.09 cm vs 1.54 ± 0.14 cm, respectively. The depth of cervical penetration increased significantly (p<0.01) in G2 and (p<0.05) in G3 compared with G1. Comparing the pregnancy rates, no significant difference was observed among the groups. However, the pregnancy rates were increased (66.67%) in G2 near to significant compared to G1 (33.33%). In conclusion, the depth of cervical penetration and pregnancy rates was deeper and higher with PGE1-Misoprostol treatment. This preliminary study enlightens the development of effective TC-AI techniques in indigenous ewes for its satisfactory pregnancy rates and, to accept by the Bangladeshi sheep farmers. Furthermore, this study provides some important results that suggest room for further research with a greater number of ewes.
