Improving Protein Utilization Efficiency Through Better Understanding of Immune and Stress Responses in Pigs27 December 2016
CANADA - Remarks by Jae Cheol Kim, Murdoch University, Australia, during the swine breakout session at the 2016 World Nutrition Forum in Vancouver, Canada.
Efficient utilization of dietary protein is affected by many factors including the animal’s physiological requirements for amino acids, genetic potential for protein deposition, digestion/absorption of dietary amino acids, use of antibiotics, and metabolism/partitioning of absorbed amino acids. Although other factors are equally important for protein utilization efficiency, this presentation will highlight the roles of immune and stress responses of pigs on protein utilization efficiency as pigs in commercial production system are exposed to considerable environmental stressors that alter the way pigs partition the absorbed nutrients. Emphasis will be given to the currently available nutritional strategies to achieve more efficient protein utilization under such environmental stress.
