Christina Larsen is a Ph.D. student from the University of Copenhagen, Denmark. She graduated from the master in Animal Science in 2019 with the master thesis “Dietary crude protein as an alternative to pharmacological zinc – the effect on diarrhea incidence, growth performance and small intestinal morphology in weaners”. From 2019 to 2020, she worked as a research assistant in the section for Production, Nutrition, and Health at the same University. Here she conducted multiple experiments on how to improve gut health, survival, and general welfare conditions for piglets to ensure the best terms from farrowing to weaning. In 2020, she started her Ph.D. in the section for Comparative Pediatrics and Nutrition at the same University. The Ph.D. title is “Microbes in early life” where she examines if transplantations with feces in neonatal piglets can be used as a prophylactic method for post-weaning diarrhea by a modulation of the microbiome. Christina came to the University of Illinois to do her “change of research environment” and she will work with the digestibility of phosphorous in different sources of wheat middlings.
