SHERIDAN, Ind., May 3, 2011 – JBS United is pleased to announce that Grant Petersen has returned to the company as a Research Nutritionist. Grant worked with JBS United from 2004 to 2007 as a Research Nutritionist, then attended the University of Illinois to earn a Doctorate of Philosophy in Monogastric Nutrition. He will continue to work in the area of swine nutrition to help producers improve the health of their pigs, while maximizing their production and profits. While previously with JBS United, Grant developed, coordinated and analyzed research trials, assisted in diet formulation at both the farm level and corporate level, and organized and maintained a corporate feed formulation system. His recently completed doctorate dissertation at the University of Illinois was focused on the determination of the tryptophan to lysine ratio in 10 - 20 kg pigs.

During his time at South Dakota State University, Grant served as a Teaching Assistant and a Graduate Research Assistant, where he worked on many swine nutrition focused projects. Grant’s vast experience in studying such a diverse range of swine nutritional issues will serve him well in his new role with JBS United. He is excited to be able to return to the company, stating, “I very much enjoyed working with JBS United previously and only left to pursue my PhD, so I’m thrilled that I was asked to return. JBS United is an exceptional company to work for and it continues to grow in the areas of animal nutrition research. I am looking forward to contributing in those efforts for many years to come.”
