Mustard is grown throughout Western Canada, primarily for use as a condiment. However, mustard growers are seeking other uses for this crop. Of interest is the potential of ground mustard as an anti-microbial. Mustard contains a compound called glucosinolate, which under the right conditions can be converted to isothiocyanate, a proven anti-microbial. This study will determine if rubbing a small amount of ground mustard on the skin of baby piglets, or placed in the sows’ environment, will reduce the environmental pathogen load those piglets are exposed to.
