Animals that had repeated cycles of proestrus, estrus, and diestrus
I and II, in that order, were called "regular cyclers.
In a different behavioral procedure, the foot placement of female rats required to traverse a narrow beam was more accurate during estrus, while more foot faults were made during diestrus
Effect of ovariectomy in the early first half of the diestrus
on induction or maintenance of canine deciduoma.
But the message doesn't seem to transmit during diestrus
, when levels of the hormone progesterone are high.
The longer estrous cycle resulted from a longer diestrus
phase, and shorter estrus and proestrus phases of the two experimental groups, as compared with the control group (p < 0.
Lower doses of DC seed extract (3-100 mg/kg BW) arrested the oestrous cycle and prolonged diestrus
, while higher doses (150-250 mg/kg BW) prolonged the oestrous stage of the cycle.
Significant differences were found between diestrus
and male groups in the prelimbic cortex (p = .
05) in the diestrus
phase and a decrease in the proestrus (p < 0.
Effect of prostaglandin E2, DL cloprostenol, and prostaglandin E2 in combination with D-cloprostenol on uterine motility during diestrus
in experimental cows.
A proestrus smear consists of a predominance of nucleated epithelial cells; an estrus smear primarily shows anucleated cornified cells; a metaestrus smear contains the same proportion among leukocytes, cornified, and nucleated epithelial cells; and a diestrus
smear primarily consists of a predominance of leukocytes.
In line to our study, reduction in the number of healthy follicles and increase in the number of atretic follicles have been reported in the ovary of immature rats (19) in which the rats received bromocriptine in drinking water from day 22 to first diestrus
Because ovulation was lesser in cows receiving the GnRH on day 3 than day 6, a new follicular wave was observed in fewer cows when the first injection of GnRH was administered during metestrus than diestrus
, thereby extending the period of follicle dominance during the Ovsynch protocol.
