Research Interests
Since joining the department in 2001, Ominski
has developed a multidisciplinary, systems-based research
program examining the productivity and environmental
sustainability of forage-based beef cattle production
systems. These projects have brought together
expertise from several university departments to examine
issues of greenhouse gas production, as well nutrient and
pathogen cycling, in both preserved forage and pasture
production systems. Involvement of provincial and
federal commodity groups and government agencies have ensured
best management practices developed as a consequence of this
research and are effectively disseminated. Prior to
joining the University of Manitoba, Kim worked as a regional
livestock specialist with Manitoba Agriculture, Food and Rural
Initiatives.
