May 2018 Lab News


Four members of our lab participated in Graduation this year. Gloria Casas, Diego Navarro, and Jerubella Abelilla all received their Ph Ds. Vanessa Lagos also completed her Master's degree and will be staying here to finish her Ph. D. Congratulations to the graduates!

Diego Rodriguez received a research scholarship from the Distillers Grains Technology Council. The award is given to current graduate students who "have completed original research which has resulted in new knowledge on distillers grains production/distribution, animal feeding (nutrition), or other applications/uses."

New experiments

Su A started two experiments: the first to determine digestibility of calcium in dicalcium phosphate, and the second to compare different ways of estimating endogenous loss of phosphorus in pigs.

Travel and visitors

Diego Rodriguez traveled to Des Moines, Iowa, on May 16-17 to participated in the 22nd Annual Distillers Grains Symposium. He received a scholarship and gave a presentation about "Nutrient and energy digestibility in Dakota Gold and conventional DDGS fed to growing pigs and growth performance and carcass characteristics of wean to finish pigs fed pelleted or meal DDGS diets."

Dr. Stein gave the following presentations in May:

  • "Effects of origin of SBM on digestibility of energy and amino acids" at a Feed Formulation Workshop in Port of Spain, Trinidad and Tobago, May 1 and 2.
  • "Calcium transporters and gene expression and absorption of calcium in pigs" and "Establishing a digestible calcium requirement for pigs" at both the Phytate Summit in Osaka, Japan, May 21-22 and at the Phytate Summit in Tainan, Taiwan May 24.
  • "Use of feed technology to improve the nutritional value of feed ingredients and diets fed to pigs" at an in-house seminar at Cargill Animal Nutrition, Taichung, Taiwan, May 25.
  • "Fiber nutrition in pigs" at the Howpro Technical Seminar in Taichung on May 25.
