Extracellular vesicles : novel mediators of conceptus-maternal interactions in sheep
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Infertility and pregnancy loss are common problems affecting reproductive efficiency, health and development in livestock. Pregnancy loss occurs most ...
Abundance of TRIM28, SETDB1, and TP53 mRNA is dynamically regulated during porcine early embryogenesis and is abnormal in preimplantation embryos produced by in vitro fertilization in comparison to in vivo derived and nuclear transfer derived embryos
(University of Missouri--Columbia, 2013)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] In vitro embryo production is important for research in animal reproduction, embryo transfer, transgenics, and cloning. However, in vitro-derived embryos ...
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 ...
Effect of ovulatory follicle size on bovine pregnancy associated glycoproteins in beef cattle
(University of Missouri--Columbia, 2010)
The GnRH-induced ovulation of small dominant follicles was associated with reduced pregnancy rates and late embryonic/fetal survival around the time of embryo-uterine attachment. PAGs are secreted by binucleated trophoblast ...
Estrus induction and maintenance of cycles in gilts with PG-600 and boar exposure
(University of Missouri--Columbia, 2007)
This study looked at the efficacy of PG-600 and boar exposure to induce and maintain cycles. Gilts received one of four treatments: PG-600, weekday 10 min full physical contact boar exposure (BE), PG-600+BE, and neither ...
The effect of reduced nocturnal temperatures on the performance of broiler chicks and hen turkey poults from 0 to 21 days of age
(University of Missouri--Columbia, 2018)
"The world population has increased over the past century and with this increase in the world population comes an increase in demand of animal protein for consumption. The United States produced 8.78 billion broilers and ...
Comparison of CIDR-based protocols to synchronize estrus in beef heifers
(University of Missouri--Columbia, 2007)
Estrus synchronization and artificial insemination (AI) are reproductive management techniques that allow beef producers to enhance the reproductive efficiency and genetic composition of their cow herd. However, U.S. beef ...
Effects of the bovine slick mutation on heat stress responses and hair growth in mice
(University of Missouri--Columbia, 2020)
The bovine slick mutations result from more than one allele variant causing a slick hair phenotype and improved thermotolerance to elevated ambient temperatures in cattle. These mutations result in the truncation of the ...
Efforts to identify large offspring syndrome during pregnancy through ultrasonography and maternal blood transcriptome analyses
(University of Missouri--Columbia, 2021)
Large offspring syndrome (LOS) is a fetal overgrowth condition observed in some bovine offspring produced in vitro. The main phenotypes of LOS is large body size due to overgrowth during development which can result in ...
Extracellular vesicles, lipids, and lipoproteins in early pregnant sheep
(University of Missouri--Columbia, 2021)
In sheep, pregnancy establishment encompasses conceptus elongation, implantation, and placentation. These events are regulated by factors present within the uterine luminal fluid (ULF) from the endometrial epithelium and ...
Evaluating progestin-based protocols to control estrous cycles of beef heifers prior to timed artificial insemination
(University of Missouri--Columbia, 2018)
The recent development of split-time artificial insemination as a breeding strategy improved reproductive outcomes following treatment with the 14d CIDR[copyright]-PG protocol; however, STAI has not been evaluated with ...
Tissue inhibitor of metalloproteinase-1 contributes to reduced fecundity in a rat model of endometriosis
(University of Missouri--Columbia, 2008)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Endometriosis affects millions of women worldwide; its symptoms are pain and reduced fecundity. An established rat model was used which endometriosis ...
Effects of late gestational copper, zinc, and manganese source and inclusion in beef cattle
(University of Missouri--Columbia, 2019)
A study was conducted to determine the effects of source and inclusion of Cu, Zn, and Mn during late gestation on cow and calf mineral status, fetal growth, and offspring immune function and pre-weaning performance. Cows ...
The role of the mammary gland during heat stress
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Disruptive effects of climate change, such as increasing environmental temperature, have direct impacts on economic viability and efficiency of food ...
Altering the timing of fixed-time artificial insemination and the interval from progestin withdrawal to prostaglandin F2a administration in estrus synchronization protocols for beef heifers
(University of Missouri--Columbia, 2022)
An experiment (Chapter 2) was designed to evaluate later timepoints for fixedtime artificial insemination (FTAI) of beef heifers, with the hypothesis that use of a later timepoint would allow a greater proportion of heifers ...
Biology of uterine glands : impact on reproductive function
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Pregnancy loss is the most common complication of human gestation, and roughly one-half of conceptions result in pregnancy loss, most frequently in the ...

DNA methylation in the early porcine embryo
(University of Missouri--Columbia, 2007)
Reproductive technologies such as in vitro fertilization, intracytoplasmic sperm injection, parthenogenetic activation, and somatic cell nuclear transfer are powerful procedures in the production of animals for agriculture, ...
Regulation of fetal brain development in short versus long lived mice
(University of Missouri--Columbia, 2022)
How fetal brain development is regulated in mice with reduced life span is a primary objective of this research. Three studies were performed to investigate the fetal brain development in short and lived mice strains. The ...
