Contribution of the Rumen Epithelial Transcriptome and Microbial Community to Variation in Beef Cattle Feed Efficiency
DownloadSpring 2016
Feed efficient cattle consume less feed and produce less environmental waste than inefficient cattle. Many factors are known to contribute to differences in feed efficiency. However, it is unknown how the rumen epithelium and its associated microorganisms influence the feed efficiency of cattle....

Aerobic methanotrophic bacteria lessen the impact of the greenhouse gas methane (CH4) not only because they are a sink for atmospheric methane but also because they oxidize it before it is emitted to the atmospheric reservoir. Aerobic methanotrophs, unlike anaerobic methane oxidizing archaea,...

Methane is the second most important greenhouse gas after carbon dioxide with a global warming potential over 100 years 25 times that of CO2. Today, anthropogenic sources of methane comprise 60% of the global methane budget per year and tools for mitigating emissions have become increasingly...

Effect of dried distillers’ grains with solubles on greenhouse gas emissions from beef cattle
DownloadSpring 2014
Four experiments were conducted to determine the impact of dried distillers’ grains with solubles (DDGS) on greenhouse gas (GHG) emissions from beef cattle. The first compared in vitro methane (CH4) production from corn DDGS (CDDGS, ~30% crude protein [CP]) and wheat DDGS (WDDGS, ~40% CP dry...

Effects of feeding 3-nitrooxypropanol to lactating dairy cows on methane emissions, animal performance and rumen fermentation
DownloadFall 2014
Methane emissions from ruminants are of great concern as they contribute to greenhouse gasses emitted within the atmosphere. The objective of this research was to evaluate a novel biochemical compound, 3-nitrooxypropanol, on its ability to reduce methane emissions and its impact on animal...

Spring 2016
The main objective of this research was to evaluate the potential of 3-nitrooxypropanol (NOP) to lower enteric methane (CH4) production by ruminants. Methane is an undesirable byproduct of enteric fermentation that represents a loss of energy to the animal. Additionally, CH4 is a greenhouse gas...

Evolutionary quantitative genetics and genomics applied to the study of sexually dimorphic traits in wild bighorn sheep (Ovis canadensis)
DownloadSpring 2011
The independent evolution of the sexes may often be constrained if male and female homologous traits share a similar genetic architecture. Thus, cross-sex genetic covariance is assumed to play a key role in the evolution of sexual dimorphism (SD) with consequent impacts on sexual selection,...

Bovine Spongiform Encephalopathy (BSE) belongs to a group of neurodegenerative diseases known as transmissible spongiform encephalopathies (TSEs) which affect many species. From 1986 more than 184,000 cattle in the UK have been confirmed to be infected with this disease, and in Canada total...
