Jonas de Souza was the 2017 Alltech Young Scientist graduate winnerr. He grew up in Brazil, where his parents raised dairy cattle. Inspired by their work, Jonas pursued animal science studies at the Santa Catarina State University. He received his master’s degree from the Luiz de Queiroz College of Agriculture at the University of São Paulo, where his research evaluated the effects of fatty acid supplementation on the performance and metabolism of dairy cows grazing tropical pastures. His doctoral dissertation at Michigan State University has focused on the effects of altering the dietary ratio of fatty acids on the energy partitioning of dairy cows under different physiological conditions.
