The Effect Of Diet On The Bovine Rumen Microbial Community Structure And Composition And Its Effects On Methane Production In Growing And Finishing Cattle, Allison L. Knoell Apr 2016

The Effect Of Diet On The Bovine Rumen Microbial Community Structure And Composition And Its Effects On Methane Production In Growing And Finishing Cattle, Allison L. Knoell

Department of Animal Science: Dissertations, Theses, and Student Research

Methane is a potent greenhouse gas (GHG) that contributes to global warming. A natural by-product of ruminant fermentation is the production and eructation of methane. Methane is produced by a small unique group of microorganism’s called methanogens that belong to the domain Archaea. Enteric methane represents 2-12% energy loss in ruminants. It is well established that diet affects the microbial community structure and composition. Fermentative products of the mixed microbial population (bacteria, fungi, and protozoa) become the substrates for methanogens. These substrates influence which microorganisms will thrive. However, the effect of diet on the microbial community while simultaneously calculating …

Erforschung biologischer Ressourcen der Mongolei / Exploration into the Biological Resources of Mongolia, ISSN 0440-1298

During a series of studies on the population, ecology, and biology of the Cinereous Vulture in Mongolia, fully feathered nestlings of the species from 9 nests were examined, without the use of chemical methods, for Mallophaga infestation from 2010 to 2015. The collection resulted in several first records for Mongolia of three species: Laemobothrion vulturis (J. C. FABRICIUS, 1775) sensu lato (Amblycera, Laemobothriidae), Neocolpocephalum aegypii (TENDEIRO, 1989) (Amblycera, Menoponidae s. l.) sp. inq., and Falcolipeurus quadripustulatus (BURMEISTER, 1838) (Ischnocera, Philopteridae s. l.). Despite being expected, there has still been no record of Agypoecus brevicollis (BURMEISTER, 1838) in Mongolia.
