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 ...
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 ...
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 ...
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 ...
Gold nanoclusters and fluorescence-based sensing
(University of Missouri--Columbia, 2017)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The main topic of this dissertation focuses on development of analytical methods, mainly modification and application of metal nanoclusters in ...
Enhancement of long-term CID R-based estrus synchronization protocols to optimize timed artificial insemination results for beef heifers and cows
(University of Missouri--Columbia, 2017)
A series of experiments was conducted to evaluate alterations to long-term progestin-based estrus synchronization protocols that may result in enhanced pregnancy rates to timed artificial insemination (AI). In the first ...
Parameterized uncertainty model using a genetic algorithm with application to an electro-hydraulic valve control system.
(University of Missouri--Columbia, 2016)
Uncertainties in the mechanical system severely increase the complexity of the system. Present the uncertainties can be parameterized by listing the coefficient from the transfer function. The attempt to reduce the ...
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 ...
Extracellular vesicles : novel mediators of conceptus-maternal interactions in sheep
(University of Missouri--Columbia, 2018)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Infertility and pregnancy loss are common problems affecting reproductive efficiency, health and development in livestock. Pregnancy loss occurs most ...
Development and analysis of a FOXA2 conditional overexpression mouse model
(University of Missouri--Columbia, 2018)
The uterus is essential for mammalian reproduction as it provides environment for conceptus implantation and subsequent development. Endometrial glands synthesize and secrete or transport substances critical for conceptus ...
Barriers and values of moral distress among critical care nurses
(University of Missouri--Columbia, 2016)
This dissertation explores the presence of moral distress and effective interventions to lessen its impact on critical care nurses. Manuscript one was completed prior to entering the doctor of philosophy in nursing program ...
Molecular characterization of a congenital overgrowth syndrome induced by assisted reproduction
(University of Missouri--Columbia, 2017)
Beckwith-Wiedemann syndrome (BWS) is a congenital overgrowth condition with increased likelihood to develop childhood tumors. Children conceived with the use of assisted reproductive technologies (ART) have an increased ...
Optimizing beef cattle performance using rumen-protected lysine supplementation in diets balanced for predicted amino acid and effective energy requirement
(University of Missouri--Columbia, 2017)
The objectives of these experiments were to determine the bypass value of rumen-protected lysine and performance responses of beef cattle fed encapsulated lysine. During experiment 1 singe-flow continuous culture fermenters ...
Role of preovulatory estradiol in uterine and luteal function
(University of Missouri--Columbia, 2018)
In beef heifers, expression of estrus at fixed-time artificial insemination (FTAI) was associated with increased preovulatory circulating concentrations of estradiol (E2) and increased pregnancy rates compared to heifers ...
Development of a fibroblast growth factor 21 assay
(University of Missouri--Columbia, 2017)
Obesity and diabetes play a major role in many diseases prevalent in our current society. Fibroblast Growth Factor 21 (FGF21) is a recently discovered hormone that has potential for therapeutic treatment of obesity and ...
Zinc ion fluxes on the pathway to mammalian sperm fertilization competency
(University of Missouri--Columbia, 2019)
For decades, the role of the divalent ion calcium was the focus of understanding mechanisms leading to sperm fertilization competency and management of semen storage. Little focus has been placed on other divalent ions, ...
Evaluation and development of early pregnancy diagnosis in dairy cattle
(University of Missouri--Columbia, 2018)
Early chemical pregnancy tests for use in dairy cattle are necessary to aid in reducing the costs associated with days the animal is not pregnant. Identifying non-pregnant dairy cattle sooner would allow for efficient ...
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 ...
