Is Tb Testing Associated With Increased Blood Interferon-Gamma Levels?, Aideen E. Kennedy, Jim O'Mahony, Noel Byrne, John Macsharry, Riona G. Sayers Oct 2017

Is Tb Testing Associated With Increased Blood Interferon-Gamma Levels?, Aideen E. Kennedy, Jim O'Mahony, Noel Byrne, John Macsharry, Riona G. Sayers

Department of Biological Sciences Publications

The Republic of Ireland reports a relatively low prevalence of Johne’s disease (JD) compared to international counterparts. Postulated reasons for this include a lower average herd size and a grass-based production system. Ireland also engages in high levels of bovine tuberculosis (bTB) testing. As interferon-gamma (IFN-γ) is believed to play a key role in protecting against JD, it is our hypothesis that administration of purified protein derivative (PPD), as part of the bTB test, is associated with a systemic increase in IFN-γ production, which may potentially limit clinical progression of the disease. We studied 265 cows (202 Friesian and 63 …

Growing Yeast For Livestock, Zachary Christman Jan 2017

Growing Yeast For Livestock, Zachary Christman

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Over 500,000 tons of organic materials such as food scraps are disposed of each year in Wisconsin. A large percentage of this material could be composted or turned into useful products. The purpose of this article is to educate farmers and organizations on how to turn food waste into a high value food source for livestock. Yeast can be grown at any time of the year without the large inputs of agricultural chemicals and machinery that is common with other feed production methods. A yeast growing facility can be scalable to any size the producer wants such as a small …


Biofilm Formation By Common Dairy Sporeformers On Native And Modified Stainless Steel Surfaces, Shivali Jindal Jan 2017

Biofilm Formation By Common Dairy Sporeformers On Native And Modified Stainless Steel Surfaces, Shivali Jindal

Electronic Theses and Dissertations

Aerobic sporeformers can be traced in a variety of dairy products such as milk powders, evaporated milk, and canned products, which demonstrates their capability of resisting high temperature treatments such as pasteurization and Ultra high temperatures. These bacilli also actively attach to the stainless steel surfaces, consequently resulting in the formation of biofilms. Product quality as well as its safety is undesirably affected by the growth of these sporeforming bacteria. Therefore, creating an ideal environment for the processing of dairy products is a critical challenge for the dairy industry. Hence, the objective of this research was to analyze various surface …


Effect Of Ultrasonication On Biofilm Forming Ability Of Common Dairy Sporeformers, Taghreed Almalki Jan 2017

Effect Of Ultrasonication On Biofilm Forming Ability Of Common Dairy Sporeformers, Taghreed Almalki

Electronic Theses and Dissertations

Sporeformers are common dairy contaminants, which are of a great concern to the dairy industry. Quality of dairy products is affected by these sporeformers such as Bacillus species, which are a significant cause of spoilage of dairy products. Thermal processes such as pasteurization have been used to inactivate pathogens, but some of the sporeformers and their endospores are resistant to such heat treatments. Beside thermal treatments, various new approaches are being developed to improve the quality of dairy products. Amongst these, ultrasonication is a promising non-thermal technique for the inactivation of thermoduric sporeformers and their endospores. Current study was carried …


Evaluación De La Suplementación Con Papa Solanum Tuberosum En La Dieta Sobre La Producción Y Calidad De Leche En Vacas De Un Hato De Chocontá Cundinamarca, Yenni Liceth García Espitia Jan 2017

Evaluación De La Suplementación Con Papa Solanum Tuberosum En La Dieta Sobre La Producción Y Calidad De Leche En Vacas De Un Hato De Chocontá Cundinamarca, Yenni Liceth García Espitia

Zootecnia

El presente trabajo de investigación evaluó la suplementación con papa (Solanum tuberosum) y sus efectos en la cantidad, calidad y costos de producción en Vacas Holstein del municipio de Chocontá, Cundinamarca, El estudio evaluó las variables cantidad de litros producidos, la calidad (%grasa, % proteína y solidos totales en la leche) durante el primer tercio de lactancia. A un grupo de vacas que parieron en la misma época se asignaron dos grupos, Control n=4 y el grupo experimental n=5, suplementadas con papa. Según el estudio realizado los resultados mostraron que la suplementación con papa no tuvo efectos significativos en la …
