Some effects of 171β-estradiol on ovine luteal function were
studied in five experiments.
Estradiol injected into ewes on days 11 and 12 of the estrous
cycle caused luteal regression in both intact and unilaterally hysterectomized
ewes indicating that the presence of one uterine horn permits
estradiol to cause luteolysis comparable...
Coopworth sheep, a newly available genotype, were compared with
other genotypes in two trials to assess cumulative lamb and wool
production and contributing components related to survival, reproduction
and growth, and for the effects of ewe body weight on reproductive traits.
In a third trial, various genotypes generated in the...
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...
Thirty-six Suffolk ewes were randomly divided into two equal
groups. One group received a selenium (Se) deficient diet, while the
other diet contained sodium selenite at a level of 0.2 ppm Se in the
total diet. All ewes were sampled for plasma glutathione peroxidase
(GPx) and whole blood Se at...
