Název v původním jazyce

Effect of simultaneous administration of PGF2α and GnRH on follicular development, oestrus and the timing of ovulation in cows

Popis výsledku v původním jazyce

The aim of this study was synchronization of oestrus in cows by simultaneous administration of PGF2&#945; and GnRH. Synchronization of oestrus was repeated in 5 cows (group I) and 32 cows (group II and III). In total 15 synchronized sexual cycles were observed in group I. Oestrus was synchronized by administration of 500 ?g of cloprostenol and 100 ?g of lecirelin. The cows were examined by transrectal ultrasonography daily from the day of treatment to occurrence of a new luteal phase, and ovarian structures were evaluated in group I. The new follicular wave occurred on the day 3 or 4 in all synchronized sexual cycles and ovulation occurred in l synchronized cycle on the day 3, in 6 cycles between days 7 and 9 and in 6 cycles between days 10 and 17 in group I. Simultaneous administration of PGF2&#945; and GnRH during the luteal phase of the sexual cycle does not represent a sufficiently efficient method of synchronization of oestrus. The majority of oestrus and ovulation occurs on days
