Applying effective energy concept for intake prediction and balancing ruminal nitrogen and post-ruminal amino acid requirements for beef cattle
(University of Missouri--Columbia, 2013)
Proper animal nutrition involves balancing nutrient supply to nutrient requirement. Accurate intake prediction is fundamental to diet formulation and appears simple but has historically been challenging to accomplish. ...
Large offspring syndrome, a bovine model for the human loss-of-imprinting overgrowth syndrome Beckwith-Wiedemann
(University of Missouri--Columbia, 2013)
Beckwith-Wiedemann syndrome (BWS) is a human loss-of-imprinting syndrome primarily characterized by macrosomia, macroglossia, and abdominal wall defects. BWS has been associated with misregulation of two clusters of imprinted ...
Characterization of a transgenic pig model carrying green fluorescent proteasomes
(University of Missouri--Columbia, 2013)
The Ubiquitin Proteasome System (UPS) participates in many biological processes involving substrate-specific proteolysis, and can be linked to various pathologies and genetic diseases. Unfortunately, little is known about ...
The effects of leptin on placental development and function, and offspring behavior in mice
(University of Missouri--Columbia, 2014)
The nutritional and energy status of individuals is communicated throughout the body by means of leptin. This hormone also plays a role in implantation and placental development and function, as well as programming behavior ...
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 ...
The inhibition of cysteine peptidases improves in vitro maturation of porcine cumulus-oocyte-complexes
(University of Missouri--Columbia, 2013)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The cell permeable cysteine peptidase inhibitor, E-64, has shown utility as a potent and irreversible inhibitor for many cysteine proteases. Consequently, ...
Effect of commercial feed additives on production variables and metabolic markers of the periparturient dairy cow
(University of Missouri--Columbia, 2013)
Three experiments were conducted to investigate the effects of commercially available feed additives on production variables and metabolic markers when supplemented during the periparturient period. The hypothesis was that ...
Analysis of Gbx genes during neural development
(University of Missouri--Columbia, 2013)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The understanding of how transcription factors regulate neural patterning in the anterior hindbrain, and how the assembly of specific neuronal circuits ...
Beef chuck muscle isolation has no effect on premium ground beef programs
(University of Missouri--Columbia, 2014)
This experiment evaluated whether isolating certain muscles from the chuck for retail sale and excluding them from the ground beef mix changes the number of days that ground chuck is acceptable to consumers. Chucks were ...
Development of a novel immunoassay for simultaneous quantification of endocrine parameters
(University of Missouri--Columbia, 2015)
Since the advent of the radioimmunoassay in the 1950s, numerous immunologically-based methods have evolved for sample analysis. Although each immunological method possesses unique assets and liabilities, all share limited ...
Use of simvastatin to inhibit advanced prostate cancer formation in the TRAMP mouse model of prostate cancer
(University of Missouri--Columbia, 2013)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] A provocative question currently proposed by the NIH is: do statin medications, which lower serum cholesterol, prevent cancer? We hypothesize that ...
Urocortin as a measure of stress in livestock
(University of Missouri--Columbia, 2012)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Stress is a fact of life for every living thing. In livestock species, stress can affect an animal's performance, thus leading to decreased profit for ...
The effects of reduced protein diets using the Missouri ideal turkey protein on male turkeys from 0 to 21 weeks of age
(University of Missouri--Columbia, 2013)
Protein is one of the major cost components in turkey diets. When diets are formulated on an ideal protein basis, the levels of crude protein decrease with the use of amino acids (AA); performance is maintained and feed ...
Effects of heat stress and fescue toxicosis on the immune system and other physiological parameters
(University of Missouri--Columbia, 2010)
Tall fescue is widely used as pasture grass in the United States, and is the most important cool season grass for grazing animals. Certain fungi also grow on these grasses which produce toxins, resulting in reduced feed ...
Feedlot cattle response to rumen undegradable protein and diet fiber level of high concentrate diets
(University of Missouri--Columbia, 2013)
Studies were conducted to determine the effects of feeding rumen undegradable protein (RUP) on subsequent feedlot cattle performance. The first experiment was conducted to determine if growth rate and gain to feed ratio ...
Considerations for reproductive management of bos indicus-influenced beef heifers
(University of Missouri--Columbia, 2017)
The Bos indicus species of beef cattle presents a number of unique reproductive challenges, especially with regard to those that influence reproductive efficiency including timely attainment of puberty, response to certain ...
An investigative study on neutron emissions from titanium- deuterium system under thermal shock
(University of Missouri--Columbia, 2017)
The purpose of this study is to investigate the titanium-deuterium system under thermal shock, as a potential neutron source. The expected neutron emission is unique, i.e. it is monoenergetic with energy of 2.45 MeV, which ...
A phenomenological study of queer and trans students of color
(University of Missouri--Columbia, 2017)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Queer and trans student experiences are understudied in higher education, quantitatively and qualitatively alike. Despite the number of studies growing ...
