Achievements
Three members of our lab participated in Graduation this year. Charmaine Espinosa received her Ph D. Molly McGhee and Diego Rodriguez also completed Their Master's degree. Molly will be staying here to finish her Ph. D. Congratulations to the graduates!
Travel and visitors
On May 5th to 8th, Dr. Hans H. Stein traveled to the 2019 AOCS Annual Meeting & Expo. He gave a presentation entitled “From Protein Digestibility Corrected Amino Acid Score (PDCAAS) to Digestible Indispensable Amino Acid Score (DIAAS)"
On May 9th, Doctor Kory Moran from Delacon USA, Inc., visited our lab. She talked about Delacon and its products: phytogenic feed additives.
On May 15th, our team visited in United Animal Health, Sheridan, IN. Su A Lee and Vanessa Lagos talked about digestible Ca in swine diets. Woongbi Kwon talked about effects of excess dietary Leu in diets for growing pigs. Joseph Limbach talked about: Effects of dietary CP level on growth performance and blood characteristics in weanling pigs and Cristhiam Muñoz talked about our new calorimeter unit for group-housed pigs.
New experiments
Hannah Bailey started an experiment "Determination of a possible carryover effect of feeding spray dried plasma protein on amino acid digestibility in nursery pigs."
Jessica Acosta started an experiment "Digestibility of amino acids in a new source of DDGS compared with a conventional DDGS", the objective of this research is to test the hypothesis that AA digestibility in a new source of DDGS is improved compared with conventional DDGS.
Minoy Cristobal started two experiments, the first is "Digestibility of phosphorus in a new source of DDGS and in conventional DDGS fed to weanling pigs", the objective of this experiment is to measure the apparent total tract digestibility (ATTD) and the standardized total tract digestibility (STTD) of phosphorus (P) in a new source of DDGS and to compare these values to the ATTD and STTD of P in conventional DDGS when fed to weanling pigs.
And the second is "Digestibility of energy in a new source of DDGS compared with a conventional DDGS", the objective of this research is to test the hypothesis that DE and ME in a new source of DDGS is improved compared with a conventional DDGS.
