Teixeira’s research focuses on improving our understanding of nutrient utilization and animal efficiency to reduce the impact of ruminant production on the environment and enhance sustainability of ruminant production systems.

Ph.D., Sao Paulo State University, Brazil, 2004
M.S., Sao Paulo State University, Brazil, 2000
B.S., Federal University of Lavras, Brazil, 1997

  • Further our understanding of energy and nutrient utilization/requirements in ruminants
  • Improve animal efficiency to alleviate the environment impact of livestock operations
  • Develop nutrition strategies to enhance sustainability of dairy production systems
  • Integrate our knowledge of ruminant nutrition to predict metabolic and production responses by using mathematical modeling
  • Collaborate with U of I dairy Extension specialists to address nutrition issues to enhance dairy sustainability
