Dietary fat source alters pork fat quality
(University of Missouri--Columbia, 2010)
During the last decade, several changes have taken place in the swine industry. There has been an increase in the use of distillers dried grains with solubles (DDGS) which, depending on the level included in the diet, may ...
Characterization of progesterone receptor (PGR) mRNA and protein isoforms in the endometrium of cyclic and pregnant pigs
(University of Missouri--Columbia, 2010)
Disappearance of the progesterone receptor (PGR) from the uterine luminal epithelium (LE) is essential for cyclicity and pregnancy in pigs. In humans, three PGR mRNA isoforms (PGR-A, PGR-B and PGR-C) arise from alternative ...
Effects of Artemisia afra and Artemisia absinthium on fertility of male mice exposed to increased ambient temperatures for 24 hours
(University of Missouri--Columbia, 2010)
Males exposed to elevated temperatures display a decrease in reproductive performance resulting in decreased profit for producers. The use of herbs to alleviate the effects of heat in tropical countries has been documented ...
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 ...
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 ...
Efficacy of interferon-stimulated genes and pregnancy-associated glycoproteins for pregnancy diagnosis within an estrus resynchronization protocol for dairy cattle
(University of Missouri--Columbia, 2010)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Reproductive management is a major economic concern in the dairy industry. Long intervals between TAI increases the days open and decrease the 21 day ...
The role of cytoplasmic polyadenylation element sequence on mRNA abundance in porcine embryogenesis
(University of Missouri--Columbia, 2010)
Development of a porcine germinal vesicle oocyte (GVO) to a 4-cell stage embryo occurs during a transcriptionally silent period when the oocyte/embryo relies on maternally derived mRNA to encode proteins required for ...
Ruminal degradation of protein and carbohydrate in the domestic and wild ruminant
(University of Missouri--Columbia, 2010)
To optimize growth and health ruminant animals in a confined setting, diets need to be formulated to provide balanced levels of rumen degradable energy and nitrogen (RDN) to maximize microbial growth while also providing ...
Size-dependent acquisition of global DNA methylation in oocytes is altered by hormonal stimulation
(University of Missouri--Columbia, 2011)
Administration of exogenous gonadotropins (superovulation) is used to increase the number of mature oocytes to circumvent the inefficiencies of the subsequent assisted reproductive technologies procedures. Some evidence ...
Function and gene expression of circulating neutrophils in dairy cows : impact of micronutrient supplementation
(University of Missouri--Columbia, 2012)
Three experiments were conducted to investigate the mechanisms of neutrophil dysfunction during the periparturient period and test potential nutritional strategies to prevent the immune-alteration typical of this time. The ...
Overcoming endometriosis-associated preimplantation embryo developmental anomalies by culture
(University of Missouri--Columbia, 2013)
Endometriosis, characterized by the localization and establishment of ectopic endometrial tissue, afflicts 10 to 15% of reproductive-aged women worldwide. Due to the anomalous substances secreted from these endometriotic ...
Stem cells and DNA methylation reprogramming in pigs
(University of Missouri--Columbia, 2013)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] In mammals, the majority of cells in the body contain the same genome as other cells. The concept of nuclear totipotency has been well demonstrated by ...
GGTA-1 targeting efficiency with a xenograft transgene
(University of Missouri--Columbia, 2012)
Gene targeting by homologous recombination was utilized to target the GGTA-1 locus. Two independent enrichment strategies were evaluated to determine if targeting efficiencies at the GGTA-1 locus could be improved. The ...
Modeling EAA requirement and developing low fishmeal diet for yellow perch
(University of Missouri--Columbia, 2013)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Overall, my dissertation research sought to enhance production of yellow perch by developing a low cost, complete diet for juvenile yellow perch by ...
Behavioral and physiological phenotype of the viable yellow mouse (AVY/a)
(University of Missouri--Columbia, 2013)
Epigenetics is the study of how heritable phenotypes are transmitted without changes being made to the DNA sequence. One of the best characterized animal models for epigenetics is the viable yellow (Avy) mouse. These animals ...
Generation and characteriazation of porcine induced trophoblast
(University of Missouri--Columbia, 2013)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Trophoblast stem cells are progenitors of all trophoblast lineages that compose fetal placental portion. Trophoblast stem cells provide an unlimited ...
NIR fluorescent sensors for blood pH and fructose
(University of Missouri--Columbia, 2013)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Blood serum parameters are tightly associated with human beings' physiological activities, therefore the real-time monitoring of blood serum parameters ...
Biomarker assessment for detection of joint pathology in horses and evaluation of the nutritional supplement Steadfast equine as a therapeutic
(University of Missouri--Columbia, 2012)
Degenerative joint disease (DJD) is one of the most prevalent musculoskeletal disorders seen in horses, resulting in loss of performance ability, early retirement and significant cost to horse owners. Biomarkers of tissue ...
Genotype by environment interactions for growth and stayability in US red Angus
