On April 2ndCharmaine Espinosa successfully defended her doctoral dissertation. Her topic was "Copper from Cu hydroxychloride in diets for pigs increases feed efficiency, improves energy utilization, and changes intestinal microbial activity".


On April 15th, Molly McGhee defended her Master's thesis, "Nutritional value of hybrid rye fed to growing pigs".  Molly will stay with us for her Doctoral studies, continuing to determine the nutritional value of hybrid rye.

We also had dinner to celebrate our graduates Charmaine Espinosa, Molly McGhee, and Diego Rodriguez. Many congratulations to them!
