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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
Effect of preovulatory follicle size on cumulus cell and follicular wall transcript abundance in beef cows
(University of Missouri--Columbia, 2017)
Gonadotropin releasing hormone (GnRH)-induced ovulation of small dominant follicles decreased pregnancy rates and increased late embryonic/fetal mortality in postpartum beef cows, which could be caused by inadequate oocyte ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
