| description | <b>Aim:</b> In this study, recipient synchronization with various
prostaglandin F<sub>2α</sub> protocols for cryopreserved embryo
transfer was examined.<p>
<b>Materials and Methods:</b> A total of 46 Brown Swiss cows
assigned randomly into three groups. Group I (n=15) cows
injected 0.150 mg cloprostenol intramuscularly at random
stage of the oestrus cycle. Following the injections, cows
were observed for oestrus for 5 days. The other cows
were received two 0.150 mg I.M. injections of cloprostenol
11 (Group II, n=15) or 14 (Group III, n=16) days apart. In
Group II and III, cows were observed for oestrus for 5 days
after the last injections. All cows were transferred embryos
cryopreserved by ethylene glycol on d 7 (oestrus
0). Pregnancy diagnoses were performed on d 28 by ultrasonography.<p>
<b>Results:</b> Injection-oestrus intervals and pregnancy rates
were 56.13±4.37 h and 53.3%; 62.40±3.42 h and 46.7%;
70.75±3.08 h and 43.8% in groups I, II and III, respectively.
Injection-oestrus interval was lower in Group I than in
Group III (p<0.05) and was similar between groups I and
II and groups II and III (p>0.05). The differences in pregnancy
rates among groups were not significant (p>0.05).<p>
<b>Conclusions:</b> All synchronization protocols evaluated
in this study can be used for oestrus synchronization for
cryopreserved embryo transfer in cows. |
