Dr. Nikoletta Such is a member of the poultry nutrition research group at the Institute of Physiology and Nutrition. Her focus is to raise awareness how nutrition can modify gut microbiota in the gut of the chicken. In recent years she has carried out several animal experiments with pro- and prebiotics and in addition to production parameters, she also investigated the bacteria composition of different gut segments. The importance of this research is, that due to the increase in antimicrobial resistant bacteria, using antibiotics in animal farming should be decreased and other dietary tools should be found to improve gut health. She also conducts research to decrease the environmental footprint of animal production, which includes finding alternatives of soybean meal in poultry nutrition and also finding out nutritional methods in order to decrease ammonia emission.
