Adaption of SCFA absorption from the rumen
Dr Greg Penner joined the Department of Animal and Poultry Science at the University of Saskatchewan in 2009 after obtaining his BSA (2004) and M.Sc. (2004) degrees from the same university, and his PhD from the University of Alberta (2009). His research covers forage utilisation, ruminant nutrition, and regulation gut function in cattle. He has developed 2 indwelling pH measurement systems that have been adopted by the research community worldwide. Dr Penner has a well-funded research programme support and has trained more than ten graduate students and post-doctoral fellowships. He has published over 60 peer-reviewed papers and held over 40 invitational presentations. Dr Penner has an active extension programme helping to communicate research results to end users and serves as the co-chair for the Saskatchewan Beef and Forage Symposium.
“My research programme focuses on the development of nutritional strategies to enhance the health and productivity of cattle. This includes fundamental research investigating gut function with an emphasis on regulatory processes involved in adaptive and recovery responses. Research techniques used within this theme include the use of Ussing chambers as an ex vivo approach and the temporarily isolated reticulo-rumen technique as an in vivo approach. Results from these studies are used within my second research topic, applied research, to evaluate efficacy of nutritional management strategies to enhance productivity and health of beef cattle, dairy cattle, and sheep.”
In the session “Absorption and Secretion”, he will present his keynote on “Short- and long-term adaptation of SCFA absorption from the rumen”.
