Estrus and Pregnancy Rates of Konya Merino Ewes Treated with a Double Injection of Cloprostenol at Different Intervals. Archiv für Tierzucht-Archives of Animal Breeding, 40(1), 57-60.0003-9438https://hdl.handle.net/20.500.12395/16582The effect of a double injection of cloprostenol given at different intervals on estrus and pregnancy rates after artificial insemination were evaluated in cycling Konya Merino ewes. Two injections of 125 mu g of cloprostenol were given to the ewes in group I (n=30), II (n=30) and III (n=31) at an interval of 8, 11 or 14 days, respectively. Ewes in group IV (n=28) served as control and received a double injection of saline at an interval of 8 days. Estrus ewes were detected by teaser rams during five days, 17 days in group IV, following the second treatment and intracervically inseminated by fresh semen. Estrus and pregnancy rates after first insemination in group I II, III and IV were 86.7, 100.0, 83.9 and 89.3% and 50.0, 60.0, 80.6 and 75.0%, respectively. It was concluded that an interval of 14 days may provide better pregnancy rates compared to those 8 and II days intervals in artificially inseminated ewes.eninfo:eu-repo/semantics/closedAccessSynchronizationCloprostenolIntervalEwePregnancyArticle4015760Q2WOS:A1997WJ94800006Q3
