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 ...
Effects of heat stress on leukocyte function and gene expression in lactating dairy cows
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The effects of heat stress in animal agriculture are expected to become more serious as global temperatures continue to increase. Negative effects on ...
Transcriptional profiling by deep sequencing indentifies [sic] differences in mRNA transcript abundance in in vivo derived vs. in vitro cultured porcine blastocyst stage embryos
(University of Missouri--Columbia, 2010)
In vitro embryo culture systems promote development at rates lower than in vivo. The goal of this project was to discover transcripts that may be responsible for a decrease of embryo competency in blastocyst stage embryos ...
Determination of allelic expression of H19 in pre- and peri-implantation mouse embryos
(University of Missouri--Columbia, 2013)
H19 is a maternally-expressed imprinted non-coding RNA with tumor suppressor activity. H19 is located in an imprinted cluster which contains the paternally-expressed fetal growth factor Igf2. Monoallelic expression of H19 ...
Potential diagnostic methods and nutritional changes to combat bovine respiratory disease in receiving cattle
(University of Missouri--Columbia, 2017)
Bovine respiratory disease (BRD) accounts for up to 70 percent of health disruptions and $500 million in associated medical costs and production losses, thus receiving considerable attention from cattle health personnel ...
Genetics in practice : applications of quantitative genetics to environment and educational pursuits
(University of Missouri--Columbia, 2018)
"The ability to elucidate quantitative trait architecture and introduce potentially beneficial traits makes introgression a useful tool. Unfortunately, due to the nature of inheritance there are certainly limitations to ...
Factors affecting neonatal and peripartum maternal metabolism and behavior in beef cattle and horses
(University of Missouri--Columbia, 2018)
Three studies were conducted to investigate perinatal changes in metabolism and behavior of beef cattle and horses. In the first study, effects of parity on perinatal nutrient availability assessed through calf size and ...
Differential gene and protein expression in pig nuclear transfer extraembryonic membranes and blastocyst stage embryos
(University of Missouri--Columbia, 2010)
Nuclear transfer (cloning) is the process of transferring a donor cell nucleus into an enucleated oocyte. The oocyte and donor cell are subsequently fused and activated to allow for nuclear reprogramming and continued ...
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 ...
