Artifi cial gastrointestinal tract


Meet Daisy, the dynamic avian intestinal in vitro system, closely guarded deep inside the Kuensebeck laboratory of Evonik. It is the brainchild of Professor doctor Stefan Pelzer, director of innovation management. Years of hard work and abundant financial funds led to the first working artificial gastrointestinal tract in a laboratory. Pelzer: ‘’The machine is an actual simulation of the chicken gut, both the lower and upper gut in one system. It is inoculated with gut content of a bird and then we are able to test probiotics and simulate disease pressure by adding undesirable bugs as well.” Daisy forms the link between classical lab work and in vivo proof in the animal. ‘’The gut is far more than just a simple tube, it is highly complicated and dynamic. It was not easy to replicate, but now we are able to test products more quickly and thor- oughly, before we do further research in the poultry house.”
