Structural variation at the KIT locus is responsible for the piebald phenotype in Hereford and Simmental cattle
(University of Missouri--Columbia, 2014)
The Spotted locus is responsible for white spotting (piebald) coat color phenotypes in cattle. Since the Hereford breed is fixed for this phenotype, we postulate that a selective sweep occurred during breed formation to ...
Transcriptional profiling to improve porcine preimplantation embryo development in vitro
(University of Missouri--Columbia, 2014)
Culture environments can have profound impacts on the developmental program of the preimplantation embryo. Even though significant improvements have been made to embryo culture environments they are still sub-optimal to ...
A survey of relationships among rare breeds of swine
(University of Missouri--Columbia, 2014)
Swine production has evolved over the last century resulting in the loss of biodiversity among breeds utilized by commercial producers. Only a handful of breeds are used extensively by these producers, with many swine ...
Characterization of interleukin-1 beta 2, a novel interleukin-1 expressed by the early pig conceptus during establishment of pregnancy
(University of Missouri--Columbia, 2014)
It is essential that the early mammalian embryo attaches to the uterus or implants to survive. Most embryonic mortality is associated with complications during this process resulting in a loss of 25-60% of embryos or ...
The effects of leptin on placental development and function, and offspring behavior in mice
(University of Missouri--Columbia, 2014)
The nutritional and energy status of individuals is communicated throughout the body by means of leptin. This hormone also plays a role in implantation and placental development and function, as well as programming behavior ...
Effects of supplementation of dietary antioxidants and chelated trace minerals in periparturient dairy cows and subsequent response to intramammary bacterial challenge
(University of Missouri--Columbia, 2014)
Two experiments were conducted to investigate the effects of supplementation of synthetic dietary antioxidants and different sources of a blend of trace minerals on two distinct situations of immune dysfunction in dairy ...
Beef chuck muscle isolation has no effect on premium ground beef programs
(University of Missouri--Columbia, 2014)
This experiment evaluated whether isolating certain muscles from the chuck for retail sale and excluding them from the ground beef mix changes the number of days that ground chuck is acceptable to consumers. Chucks were ...
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, ...
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 ...
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 ...
Characterization of grape condensed tannins and their effect on Black Rhinoceros (Diceros bicornis) hindgut fermentation
(University of Missouri--Columbia, 2014)
African black rhinoceros wild populations have decreased 97 percent since the 1960s, mainly as a result of poaching and the species is classified as Critically Endangered. Captive populations are managed to ensure survival ...
Identification of California Condor (Gymnogyps californianus) estrogen receptors 1 and 2 and their activation by suspected environmental contaminants
(University of Missouri--Columbia, 2014)
The recovery of the critically endangered California condor has required significant human intervention and management. Inland condor populations primarily face challenges associated with lead poisoning, which contributed ...
Biological characteristics of Katahdin sheep selected for footrot resistance
(University of Missouri--Columbia, 2014)
The objectives of this study were to select sheep divergent for a footrot resistant genotype by screening with the DQA2 gene marker and to investigate the host resistant immune response, neutrophil phagocytic efficiency, ...
