Improving viability of immunodeficient RAG2-/- pigs by non-specific porcine antibody administration
(University of Missouri--Columbia, 2020)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Immunodeficient swine models such as the RAG2-/- model, are valuable to the field of regenerative medicine; however, their utility would greatly benefit ...
Biology of uterine glands : impact on reproductive function
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Pregnancy loss is the most common complication of human gestation, and roughly one-half of conceptions result in pregnancy loss, most frequently in the ...
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 ...
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 ...
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 ...
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 ...
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. ...
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 ...
Potential diagnostic methods and nutritional changes to combat bovine respiratory disease in receiving cattle
(University of Missouri--Columbia, 2017)
Bovine respiratory disease (BRD) accounts for up to 70 percent of health disruptions and $500 million in associated medical costs and production losses, thus receiving considerable attention from cattle health personnel ...
Phosphorus digestibility of corn and soybean meal (SBM) in broilers : in search of a consistent and reliable model to quantify individual ingredient contribution
(University of Missouri--Columbia, 2017)
Two experiments were conducted to determine true digestibility of Phosphorus (P) in feed ingredients commonly in commercial broiler diets. A second objective was to determine if the true digestible P values of corn and ...
The impact of fescue toxicosis & T-Snip score on post-weaning beef cattle performance
(University of Missouri--Columbia, 2017)
It is well known that fescue toxicosis has a negative impact on cattle productivity. These studies were conducted to evaluate the effects of fescue toxicosis on post-weaning beef steers, as well as the impact of T-Snip ...
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 ...
Ruminal degradation of protein and carbohydrate using a batch culture system, and response to roughage removal, rumen modifier inclusion and postruminal amino acid supply in feedlot cattle
(University of Missouri--Columbia, 2017)
Three main studies were conducted to characterize protein and carbohydrate ruminal degradation using a batch culture system, demonstrate and responses to roughage removal, rumen modifiers inclusion and postruminal amino ...
Biological role of conceptus derived factors during early pregnancy in ruminants
(University of Missouri--Columbia, 2016)
In cycling domestic animals, pregnancy loss during early gestation is a major cause of infertility. The majority of pregnancy loss during this time is due to errors in mitotic division early in development, or occurs later ...
Evaluation of heat-processed sorghum, high-oleic and low-trypsin inhibitor soybean cultivars as alternatives for corn and conventional soybeans for broilers
(University of Missouri--Columbia, 2017)
Four 21-d experiments were conducted to compare soybean meal (SBM) from high oleic to parent soybean cultivars on growth performance, energy and ileal AA (IAA). Soybean meal was prepared by laboratory-scale mechanical ...
