Altered microrna expression profiles in bovine fetuses with an assisted reproduction-induced congenital overgrowth syndrome
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Assisted reproductive technologies (ART) refer to a series of fertility treatments used to conceive offspring. ART is used worldwide in humans for treatment of infertility...
New perspective on the role of conceptus estrogens in conceptus development, maternal recognition, and the establishment of pregnancy in pigs.
(University of Missouri--Columbia, 2018)
The proposed signal for maternal recognition of pregnancy in pigs is estrogen, produced by the elongating conceptus. To understand the role of estrogen in porcine conceptus elongation and pregnancy establishment, a loss ...
Investigation of mechanisms associated with establishment and maintenance of pregnancy in beef cattle
(University of Missouri--Columbia, 2020)
time (e.g. 66 h post PG) and heifers that are nonestrual at that time are inseminated 24 h later (e.g. 90 h). Experiment 2 was designed to test the hypothesis that delaying the first timepoint from 66 h to 72 h would increase estrous response...
The effects of elevated temperature on preimplantation-stage porcine embryos
(University of Missouri--Columbia, 2006)
It was the objective of these experiments to more fully characterize the biochemical and developmental responses of in vitro-produced preimplantation stage porcine embryos to elevated temperatures. In vitro fertilized (IVF) ...
Genetic and nutritional effects on reproduction in lactating dairy cows
(University of Missouri--Columbia, 2020)
Good reproductive performance is a prerequisite for profitable pasture-based seasonal calving systems of milk production. The objective of this dissertation was to elucidate the physiological mechanisms contributing to ...
