This is the very first report that suggests high pregnancy rates can be obtained with use of
the Doublesynch protocol in anestrous dairy cows. Recently, a new synchronization method …

The objective of this study was to evaluate the effect of a PGF2α-analogue (PGF) on

Bovine fertility is the subject of extensive research in animal sciences, especially because
fertility of dairy cows has declined during the last decades. The regulation of estrus is …

Experiments were conducted to investigate (a) the timing of ovulation and the associated
endocrine changes (progesterone, estrogen and LH) during estrous cycle and (b) the …

The aims of this study were to evaluate the effects of an intravenous or intramuscular PGF2α
analogue administration on the day of estrus on progesterone concentration and pregnancy …

The effect of intravenous cloprostenol treatment at the time of insemination on reproductive
performance was consecutively evaluated in three different subpopulations of high …

The present study aimed to determine the effect of administrating prostaglandin F2α
(PGF2α) and GnRH at the time of artificial insemination (AI) on the pregnancy per artificial …

Two experiments were conducted to evaluate if an additional prostaglandin F 2α (PG)
injection during an estradiol-based estrous synchronization treatment regimen affects …

Milk progesterone concentration (P4), milk yield, milk composition, ovarian structures and
