Experiments were conducted to characterize the nongenomic effects of
progesterone (P4) on binding of oxytocin (OT) to the ovine oxytocin
receptor (OTR) and signal transduction. The dose-response relationship of
P4 to OT binding to the OTR in endometrium was examined. Progesterone
interfered with the binding of OT to the OTR...
Alfalfa accumulates phytoestrogens and when ingested binds the estrogen receptor and induces morphological changes similar to endogenous estrogens. The objective of this study is to evaluate morphological changes in uteri, vulva, and teats of ovariectomized prepubertal ewe lambs. Eighteen prepubertal ewe lambs were ovariectomized in November 2000 and fed nonestrogenic...
Two trials were conducted over consecutive years to examine the effects of ewe
body condition and post-mating nutrition on ovulation rates and embryo survival. Trial 1
used 146 Polypay ewes ranging in age from 5 to 8 years in a 3 x 2 factorial array of pre-mating
(high-H, low flushed-LF...
