John Htoo

Director Global Technical Support (Swine), Evonik Nutrition & Care

Dr. Htoo obtained a B.Sc. agr. (Animal Production) from Larenstein International University, Deventer, Netherlands, and a M.Sc. agr. and a Dr. sc. agr. (Animal nutrition) from Georg-August University, Goettingen, Germany. After serving as a Postdoctoral Research Fellow from 2004 to 2006 at the University of Alberta, Edmonton, Canada, he started his career at Evonik in 2007 as a research manager in swine nutrition. He was responsible for planning and management of a large number of swine research projects covering a broad range of topics in collaboration with leading researchers from various universities and institutes worldwide. Since January 2018, he took over the responsibility as the Director Technical consulting – swine belonging to the team of Animal Production Experts. His main research topics include the estimations of amino acids requirements and ideal protein ratios, the interactions of immune status and amino acids requirements, further development of advanced feeding concepts such as low protein diets, the next limiting amino acids, net energy requirements, and updating the standardized ileal amino acids digestibility of feed ingredients for pigs. As author and co-author, he has contributed more than 90 peer-reviewed journal articles, 100 conference proceedings, 11 technical review articles and 2 invited keynote presentations.

Say no to nitrogen:  An integrated low protein diet concept that can increase nutrient efficiency and minimise the environmental impact of pig production

As the global demand for meat increases regulations to reduce the nitrogen pollution caused by intensive livestock production are being strengthened. In an effort to reduce nitrogen excretion the industry is seeking to reduce the use of feeds containing excess crude protein and replace them with a balance of feed grade amino acids in order to maintain optimal pig performance.  John will show that an integrated approach, using low crude protein diets with a net energy system, probiotics and fibre sources, improves gut health, nutrient utilization and efficiency. His update will cover…

  • The application of low crude protein diets fortified with amino acids on the performance and nitrogen excretion of growing-finishing pigs
  • Reasons for inconsistent pig performance results when dietary crude protein content is reduced more than 4 %
  • Latest feeding concepts to lower crude protein content without compromising pig performance and carcass quality
  • Further potential to reduce nitrogen excretion and global warming, discovered in Germany and applicable on a global scale
