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 …

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 …

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

In vitro fertilization studies have demonstrated that contact with the female reproductive tract
is not necessary in order for the embryo to reach the hatched blastocyst stage. Furthermore …

The ability to induce ovulation with an injection of GnRH facilitated the development of fixed-
time artificial insemination (AI) protocols. However, animals that exhibit estrus prior to fixed …

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 aim of this study was to identify conceptus-derived proteins, in addition to IFNT, that may
facilitate pregnancy recognition in cattle. Analysis of the protein content of the uterine …

The aim of this study was to test the effect of expression of estrus at artificial insemination
(AI) on endometrium, conceptus, and CL gene expression of beef cows. Thirty-six …

Pregnancy success is critical to the profitability of cattle operations. However, the molecular
events driving the uterine tissue towards embryo receptivity are poorly understood. This …
