Personnel changes

Andrea Mallea from Peru came in 2020 to work at the farm and she started this Spring like a master student with Dr. Stein. 

Dr. Hans Stein started his sabbatical time in the National University of Colombia.


New experiments

Jessica Acosta started an experiment about assessing the effect of xylanase and xylo-oligosaccharide on growth performance, gut health, and the digestibility of nutrients in weanling pigs.
