Petra Fant
PhD student in Animal Science


I am a third year PhD student in animal science at the Department of Agricultural Research for Northern Sweden at SLU in Umeå.


My research project called "Oats for more sustainable milk production and a better environment" focuses on mitigation of enteric methane emissions from dairy cows. The project will investigate whether enteric methane emissions can be decreased by replacing barley with oats in the diet of dairy cows without compromising animal productivity. The project will also explore whether the nutritional quality of milk in terms of milk fatty acid composition can be improved by replacing barley with oats. In addition, the rumen microbiome will be studied in detail. 


I graduated from the University of Helsinki in 2017, with a Master's in animal science and specialization in animal nutrition.
