RESEARCH AND EXTENSION OVERVIEW

Research and extension programs complement each other and are geared towards helping both the poultry industry and the backyard poultry farmer in areas of poultry health, environmental issues and biosecurity. His background in genetics, immunology and pathogenic diseases gives him a unique perspective on how to reduce or control diseases that affect chickens.

Currently his research involves determining the efficacy of various feed additives in reducing foodborne bacteria (Salmonella spp, Campylobacter spp, Clostridium perfringens) and pathogens (Clostridium spp, Escherichia coli, Eimeria spp) in poultry. He is also interested in management practices that will reduce pathogens in poultry houses. A reduction of pathogens in the poultry house should increase bird live performance as well as reduce the incidence of these pathogens entering the human food chain. Another area that he devotes his efforts is in safe handling and disposal of poultry litter, which is a serious problem in all of the poultry producing states. One method to control this problem is in-house windrow composting, which Ken has shown to be effective in eliminating most pathogenic organisms.
