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 ...
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 ...
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 ...
Strategies to improve stored forage use efficiency
(University of Missouri--Columbia, 2015)
Two experiments evaluated collection frequency impacts on forage waste estimates and bale diam., stocking rate, and feeder design influences on waste level. In Exp. 1, waste collection daily (DLY) reduced (P < 0.05) estimates ...
Timing of ovulation in gilts treated with different regiments of OvuGel(R) and Matrix(R)
(University of Missouri--Columbia, 2015)
Previous research has shown that 85% of gilts treated with Matrix(R) will show heat (estrus) 4-9 d after last Matrix(R) feeding. Synchronization of estrus is important in knowing when to inseminate (breed). This window of ...
Mu-synthesis controller design for temperature control of a solar steam gasifier with uncertainty modeling and robust analysis
(University of Missouri--Columbia, 2015)
Gasifiers operate by inputting a carbon rich material, water, and heat into a reactor core to cause a chemical reaction to produce a desired chemical composition output. For this work, a unique hybrid allothermal/autothermal ...
Selection for parasite resistance in Kiko x Boer goats
(University of Missouri--Columbia, 2015)
In the United States, goat production has increased over the last three decades because of their economic value as efficient converters of low-quality forages in quality meat, milk, and hides for specialty markets. However, ...
Development of a pregnancy associated glycoprotein assay to detect late embryonic mortality in cattle
(University of Missouri--Columbia, 2015)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Embryonic mortality (EM) decreases profitability of a beef or dairy operation because of the impact that it is has on delaying the time of conception ...
Strategic progesterone testing as a method to predict conception and manage reproduction in dairy cows
(University of Missouri--Columbia, 2015)
Timed AI (TAI) programs have increased reproductive efficiency in dairy herds, but conception rates to TAI remain below 50% for most herds. The low TAI pregnancies per AI (P/AI) is partially explained by cows that do not ...
Comparison of rumen microbe taxa among wild and domestic ruminants
(University of Missouri--Columbia, 2015)
Microbes that inhabit the rumen provide a diverse set of enzymes that degrade ingested plant material. Without microbes, ruminants could not survive. Our research has focused on identifying microbial taxa associated with ...
Determining best predictors of animal performance in feedlot steers
(University of Missouri--Columbia, 2015)
Two studies were performed in a feedlot environment to determine the long-term effects of heat events on animal performance and well-being. Experiments in this thesis were designed to pinpoint ambient variables that most ...
Efficacy of adsorbents and antioxidants in reducing the effects of mycotoxins in broilers and pigs
(University of Missouri--Columbia, 2015)
Feed is the most expensive aspect of livestock production, accounting for around 69% of total cost (Donohue and Cunningham, 2009). This high cost drives the incentive to offer a properly balanced diet, which supplies the ...
A survey of relationships among rare breeds of swine
(University of Missouri--Columbia, 2014)
Swine production has evolved over the last century resulting in the loss of biodiversity among breeds utilized by commercial producers. Only a handful of breeds are used extensively by these producers, with many swine ...
Transcriptional profiling to improve porcine preimplantation embryo development in vitro
(University of Missouri--Columbia, 2014)
Culture environments can have profound impacts on the developmental program of the preimplantation embryo. Even though significant improvements have been made to embryo culture environments they are still sub-optimal to ...
Modulation of inflammatory responses by Sutherlandia frutescens
(University of Missouri--Columbia, 2015)
Sutherlandia frutescens (L.) R. Br (Lessertia frutescens) is a medicinal plant traditionally used in southern Africa. It has been used for patients suffering from numerous types of cancer, infectious diseases, and various ...
Understudied chromosomes : an analysis of the canine mitochondrial genome and bovine Y chromosome
(University of Missouri--Columbia, 2015)
Certain regions of the genome are more difficult to study than others due to intrinsic characteristics of the region. The mitochondrial genome is small with high copy number and therefore easy to sequence. The challenge ...
Feed additives affect pork quality and shelf-life from pigs fed ethanol co-products and pork subject to three storage methods
(University of Missouri--Columbia, 2011)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Two experiments were performed to determine the effect of corn distiller's dried grains with solubles on meat quality when fed at two different inclusion ...
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 ...
Response of Bos taurus cattle to fescue toxicosis and heat stress comparing by region and breed
(University of Missouri--Columbia, 2011)
Two studies were performed to determine response differences in heat-sensitive and -tolerant Bos taurus cattle to heat stress and fescue toxicosis in controlled and field environments. Romosinuano (RO), a tropically adapted ...
Tissue inhibitor of metalloproteinase-1 contributes to ovulatory dysfunction in a rat model of endometriosis
(University of Missouri--Columbia, 2011)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Endometriosis causes ovarian dysfunction, but the mechanisms are unknown. These experiments utilize a rat model of surgically-induced endometriosis ...
