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, ...
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 ...
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 ...
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 ...
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 ...
Efficacy of various wavelengths of light emitting diode illumination on efficiency and performance parameters of broilers
(University of Missouri--Columbia, 2016)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Lighting is essential for broiler growth, maturation, and reproduction. Globally, broilers are reared under various production systems including outdoor ...
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 ...
Contemporary light sources and their impact on the discoloration and oxidation of fresh beef products
(University of Missouri--Columbia, 2017)
Discolored fresh meat products in a retail setting are often perceived negatively by consumers when making purchasing decisions. Prolonging fresh meat color is critical for the retail industry in regard to sales and consumer ...
Genetic linkage of multiple modifications in the pig
(University of Missouri--Columbia, 2015)
Genetic engineering facilitates heritable modification of target genomes. Modifications can be site-specific or random. Though inefficient, homologous recombination allows for precise genome modification. Random integration ...
Evaluation of exogenous plant based enzymes in a low-cost foodservice beef model
(University of Missouri--Columbia, 2016)
This study was performed to determine the effects of an exogenous enzyme on the tenderness of beef hanging tenders over a 3-day storage period. The objectives were to evaluate the Slice Shear Force, myofibrillar fragmentation ...
Metabolic programming of a Warburg effect-like phenotype in donor fibroblasts prior to somatic cell nuclear transfer
(University of Missouri--Columbia, 2017)
Gene edited pigs serve as excellent models for biomedicine and agriculture. Currently, the most efficient way to make a reliably-edited transgenic animal is through somatic cell nuclear transfer (SCNT) also known as cloning. ...
Autophagy and ubiquitin-proteasome system during post-fertilization sperm mitophagy
(University of Missouri--Columbia, 2016)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Maternal inheritance of mitochondria and mitochondrial DNA (mtDNA) is a universal principle in developmental biology. Mammalian sperm-borne mitochondria ...
Effect of subclinical endometritis on ovarian and uterine response to a timed AI protocol in dairy cows
(University of Missouri--Columbia, 2016)
During parturition the uterus of the dairy cow is more exposed to the environment. Bacteria colonize the uterus causing infection. The immunological response of the cows is able to clear infection, however, around 20% of ...
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 ...
Novel feed additives to improve lipid profiles in pigs
(University of Missouri--Columbia, 2016)
Opportunities to export high quality pork products to trade partners like Japan are economically favorable outlets for US pork producers. Domestic consumers also rely heavily on fresh pork appearance, especially color and ...
The effect of various levels of yellow grease in pre-starter rations on performance of turkey poults
(University of Missouri--Columbia, 2016)
Nutritional intervention in the early growing poult can be a valuable strategy to decrease the stress experienced during the transition from endogenous yolk sac lipid reserves to an exogenous feed source. The objective of ...
Diet shifts provoke complex and variable changes in the metabolic networks of the ruminal microbiome
(University of Missouri--Columbia, 2016)
Grazing mammals rely on their ruminal microbial symbionts to convert plant structural biomass into metabolites they can assimilate. To explore how this complex metabolic system adapts to the host animal's diet, we inferred ...
Multivariate genome-wide association studies and genomic predictions in multiple breeds and crossbred animals
(University of Missouri--Columbia, 2016)
The aim of the first research project is to design a commercialized genomic test that strongly predicts meat tenderness and other carcass traits in multiple breeds and crossbred cattle. We have identified single nucleotide ...
Nutritional intervention in the early growing broiler chick
(University of Missouri--Columbia, 2016)
As the broiler chicken continues to grow faster and larger, the time to slaughter continually decreases. Broilers are commonly slaughtered at 5-8 weeks of age and so the post-hatch period has become a larger and more ...
Postpartum hormones and metabolites affecting fertility in Holstein and Jersey dairy cows
(University of Missouri--Columbia, 2016)
Dairy cows have experienced major changes in productivity during the past 70 years. A selective pressure was applied to increase milk yield, but fertility declined. During early lactation, dairy cows are exposed to ...
