EFFECT OF SIMULTANEOUS APPLICATION OF PGF2alfa AND GnRH ON FOLLICULAR DEVELOPMENT, OESTRUS AND THE TIME OF OVULATION IN COWS

Original language description

The aim of this study was synchronization of oestrus in cows by simultaneous application of PGF2 ? and GnRH. Synchronization of oestrus was repeated in 5 cows housed at the department of the university (group I) and 32 cycling cows in dairy farms (groupII and III). In total 15 synchronized sexual cycles were observed in group I. Oestrus was synchronized by intramuscullar application of 500 #g of cloprostenol (Oestrophan, Ferring-Léčiva, Prague, Czech Republic) and 100 #g of lecirelin pro toto (Supergestran, Ferring-Léčiva, Prague, Czech Republic) at the same time during the luteal phase of the sexual cycle. The cows were examined by transrectal ultrasonography daily from the day of treatment (day 0) to occurrence of a new luteal phase, and ovarian structures were evaluated in group I. Ultrasonographical examination of ovarian structures were performed on the day of treatment (day 0) and on days 3, 7 and 14 and samples of peripheral blood for progesterone determination by ELISA were ob
