  • 2003 – Ph.D., Poultry Science, Auburn University
  • 1995 – M.S., Biology, Northern Illinois University

  • Farm food safety
  • Bacterial disease control and prevention
  • Parasite control and prevention in poultry


Currently Dr. Macklin’s lab research involves determining the effect of various feed additives (pre- and probiotics, competitive exclusion, feed ingredients and pharmaceutical) on 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 both poultry and food 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.

Having a 50% extension and research appointment means that Ken’s programs must complement each other. His extension programs are geared towards helping both the commercial poultry industry as well as the small flock producer in areas of biosecurity, poultry health, food safety and environmental issues. Ken’s background in genetics, immunology and bacteriology gives him a solid foundation on how to control these issues.
