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 ...
Comparison of thermoregulatory mechanisms in heat sensitive and tolerant breeds of Bos taurus cattle
(University of Missouri--Columbia, 2008)
Two Bos taurus breeds with known differences in heat tolerance were tested under controlled conditions to evaluate heat tolerance. Romosinuano (RO) is a tropically adapted breed. Nine Angus (304 [plus or minus] 7 Kg BW; AG) and nine RO (285 [plus...
Use of the veterinary medical database to update the veterinary oncology literature
(University of Missouri--Columbia, 2009)
of the advantages and disadvantages that associated with the VMDB. In chapter 2 we evaluate the breed distribution of the VMDB and compare it to that of the AKC. We conclude that the two datasets have similar breed presentations and that the VMDB is more...
Genotype by environment interaction estimated by using reaction norms in cattle
(University of Missouri--Columbia, 2008)
regression (RRM)) for estimating breeding values and heritabilities. Fixed effects included year-season, contemporary group, and sex. The RRM produced reaction norms for each bull which were calculated by regressing progeny means within an environment...
Net energy content of soybean meal and glycerol for growing and finishing pigs
(University of Missouri--Columbia, 2009)
Net energy systems are widely accepted and utilized throughout Europe. The main net energy systems used are the French INRA, the Dutch CVB and the Danish PPE. These energy systems are not widely accepted in the U.S. due ...
Implementation of high-density SNP data for genetic evaluation and QTL discovery in beef cattle
(University of Missouri--Columbia, 2009)
was used to estimate breeding values (EBVs) on both sires and steers and residuals were estimated on the steers. EBV and residuals were combined to produce adjusted phenotypes corrected for fixed effects (year and season of birth within feeding pen...
A study of the factors influencing the ability of the animal to digest its food
(University of Missouri--Columbia, 1916)
different conditions. The animals selected for use in digestion trials represented a variety of conditions and treatment. Two kinds of animals were used for these experiments - steers and swine (gilts). The principal factors studied with steers were...
Prenatal growth of the pig
(University of Missouri--Columbia, 1910)
Numerous observations on various phases of growth are to be found in the biological literature. Most of those concerning prenatal growth are upon the human embryo; although scattered observations are also recorded on other ...
11 [beta]-hydroxysteroid dehydrogenase activity in feline, equine, and ossabaw swine adipose tissue
(University of Missouri--Columbia, 2007)
Enzymatic 11 [beta] HSD1 amplification of glucocorticoid concentrations in adipose tissue has been associated with obesity, diabetes, hypertension, dyslipidemia, and cardiovascular disease in humans and mice. Unfortunately, ...
Taxonomic and metagenomic approaches to diet, health, and breeds of ruminants
(University of Missouri--Columbia, 2020)
this approach to explore the complexities of the rumen ecosystem and to assess the effects of feed additives in diet, feed efficiency, and breed-differences on this ecosystem. We linked the metabolic network of the microbial community to that of the host animal...
An examination of influenza immunity in pigs and their role in assessing antiviral therapies for humans
(University of Missouri--Columbia, 2022)
The lung is dynamic barrier organ with a complex cell population. Pulmonary immune cells must balance an effective and tolerogenic response to keep homeostasis. Due to numerous similarities to the human respiratory system, ...
Mitigation of summertime boar infertility by evaporative and conductive cooling
(University of Missouri--Columbia, 2018)
Boars subjected to summertime temperatures results in reductions in sperm quality. This reduction in quality is associated with decreases in both litter size and conception rate. With this study we aim to quantify the ...
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 ...
Evolution, transmission, and clinical impacts of SARS-CoV-2 and influenza viruses
(University of Missouri--Columbia, 2023)
[EMBARGOED UNTIL 12/1/2024] Influenza and coronaviruses are leading causes of human respiratory diseases, causing substantial global impact. The ongoing evolution of SARS-CoV-2 and influenza viruses continues to trigger ...
Tales of an 'invisible' life stage : survival and physiology among terrestrial juvenile ambystomatid salamanders
(University of Missouri--Columbia, 2019)
to their small body size and often elusive life histories. The main objective of this dissertation was to elucidate survival rates, and physiological characteristics that contribute to survival, among terrestrial juveniles of multiple complex lifecycle pond-breeding...
Application of the systems approach : an information and decision model for the hog enterprise
(University of Missouri--Columbia, 1976)
"Subject of Dissertation: The purpose of this dissertation is to develop a dynamic model for hog enterprises in which a complete information system is incorporated. It will provide the farmer with several plans of action, ...
Nested association mapping and accuracy of predicting genomic breeding value for agronomic and seed composition traits in three interspecific soybean populations
(University of Missouri--Columbia, 2019)
maximized (Across all families design) produce robust prediction accuracies for yield, maturity, protein, and oil. Genomic predictions might also accelerate genetic gain in pre-breeding efforts using wild soybeans....
Involvement of mitochondrial transcription factor A (TFAM) in porcine gametogenesis and preimplantation embryo development
(University of Missouri--Columbia, 2007)
Mitochondrial Transcription Factor A (TFAM) is responsible for maintenance and transcriptional control of mitochondrial DNA (mtDNA). TFAM knockout is embryolethal. We have studied the expression and distribution of TFAM ...
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 ...
