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 ...
Effects of aflatoxin B₁ (AFB₁) on hepatic gene expression in pigs and turkeys
(University of Missouri--Columbia, 2013)
The objective of the present study was to evaluate the efficacy of curcumin (CMN), an antioxidant supplied by turmeric (Curcuma longa) powder to ameliorate the adverse effects of aflatoxin B1 (AFB1) on performance of pigs ...
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 ...
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 ...
The role of postruminal amino acid supply and mitochondria function on residual feed intake
(University of Missouri--Columbia, 2014)
Residual feed intake (RFI), used as a metabolic efficiency measurement, is BW and growth rate independent and also is a moderately heritable trait. Previous research reported RFI was correlated to feed activity and behavior, ...
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 ...
Impact of zymannase on growth performance, carcass characteristics, fat quality and processed meats in finishing barrow fed 30% dried distiller's grains with solubles
(University of Missouri--Columbia, 2014)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] As ethanol production continues to increase, so does the use of dried distiller's grains with solubles (DDGS) in swine diets. The effects of high ...
Immune Mediators of Murine Lyme Arthritis
(University of Missouri--Columbia, 2014)
Lyme disease is the most common vector-borne disease in both the United States and Europe; however, its pathogenesis is incompletely understood. The studies described in this thesis aid in the elucidation of mechanisms ...
Characterization of grape condensed tannins and their effect on Black Rhinoceros (Diceros bicornis) hindgut fermentation
(University of Missouri--Columbia, 2014)
African black rhinoceros wild populations have decreased 97 percent since the 1960s, mainly as a result of poaching and the species is classified as Critically Endangered. Captive populations are managed to ensure survival ...
Shelf stability and quailty of fresh ground pork and pork sausage from pigs fed ethanol co-products
(University of Missouri--Columbia, 2011)
This experiment was conducted to determine the effect of swine diets on subsequent meat quality characteristics and shelf life of ground pork products. Pigs were fed one of 8 different dietary treatments using dietary ...
Identification of California Condor (Gymnogyps californianus) estrogen receptors 1 and 2 and their activation by suspected environmental contaminants
(University of Missouri--Columbia, 2014)
The recovery of the critically endangered California condor has required significant human intervention and management. Inland condor populations primarily face challenges associated with lead poisoning, which contributed ...
Biological characteristics of Katahdin sheep selected for footrot resistance
(University of Missouri--Columbia, 2014)
The objectives of this study were to select sheep divergent for a footrot resistant genotype by screening with the DQA2 gene marker and to investigate the host resistant immune response, neutrophil phagocytic efficiency, ...
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 ...
Improvement in stored forage utilization during feeding
(University of Missouri--Columbia, 2013)
Three experiments investigated methods to reduce forage waste during stored forage feeding using large round bale feeders (LRBF). In the first experiment, cone and sheeted LRBF reduced (P < 0.05) fescue hay waste 54 and ...
