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.
