Preovulatory estradiol is known to impact embryo quality and survival. The objective of this
study was to determine the effects of preovulatory estradiol on the uterine environment and …

The uterine environment must provide sufficient endocrine conditions and nutrients for
pregnancy maintenance and conceptus survival. The objective of this study was to …

Embryo survival and pregnancy success is increased among animals that exhibit estrus
prior to fixed time-artificial insemination, but there are no differences in conceptus survival to …

This experiment was conducted to determine the effect of altering preovulatory estradiol
concentrations, through manipulation of length of proestrus, on peripheral progesterone …

This study was carried out to evaluate effects of pre-ovulatory follicle size, plasma
concentrations of estradiol and progesterone, and season on pregnancy outcomes in dairy …

Abstract Approximately 65–75 days postpartum (dpp), the estrous cycles of nonlactating
(dried off immediately postpartum: n= 12) and lactating (n= 13) Holstein Friesian cows were …

The role of preovulatory estradiol on post-fertilization embryo survival and pregnancy
establishment has not been well characterized in beef cows. We hypothesized that …

Embryos were collected non-surgically from the tip of one uterine horn of 23 lactating dairy
cows on Day 7 of pregnancy. Embryos were classified on the basis of morphological criteria …

During previous investigations, the capacity of the cow to secrete prostaglandin in response
to oxytocin has been linked with pregnancy outcome. The objective of the present study was …

Efficient pasture-based milk production systems require a compact calving pattern aligned to
the onset of the grazing season, a 365-day calving interval and low culling rates for infertility …
