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 ...
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 ...
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 ...
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 ...
Metabolic status of late gestation beef cows and neonatal calves
(University of Missouri--Columbia, 2016)
Two studies were conducted to investigate the changes in beef cattle metabolic status over time. In the first study, the effects of grazing stockpiled tall fescue (STF) versus feeding tall fescue hay during late gestation ...
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 ...
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 ...
Genomic localization of a feline congenital hydrocephalus
(University of Missouri--Columbia, 2016)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] An inherited congenital hydrocephalus (CH) was identified after an Oriental shorthair male with "cobby" ears was used in the development of Toygers, ...
Modification of porcine rhodopsin by CRISPR/Cas9 : towards a model for Retinitis Pigmentosa
(University of Missouri--Columbia, 2016)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Retinitis Pigmentosa (RP) is a disease characterized by progressive vision loss, which affects approximately 1 in 4,000 people in the United States. ...
Effect of pre-ovulatory follicle size on oocyte transcript abundance in beef cows
(University of Missouri--Columbia, 2016)
Inadequate oocyte competence is a potential explanation for reduced pregnancy rates and(or) increased late embryonic mortality when small dominant follicles are induced to ovulate prematurely with gonadotropin releasing ...
Evaluation of the retail display life of ground beef stored in modified atmosphere packaging and modern lighting conditions
(University of Missouri--Columbia, 2016)
Color is the most important factor in decision making for the consumer in the retail setting. The objective of this study was to determine the color stability of ground beef patties packaged in modified atmosphere packaging ...
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 ...
