Achievements
From July 13 to 16 Elizabeth Guevara participate in the NPIC 2025 in Wisconsin Dells/ Wisconsin.
Conferences
Dr. Stein gave some talks at DSM-Firmenich. Workshop on “The future of Calcium nutrition in monogastrics”. Kaiseraugst, Switzerland. July 7-10:
- Requirements of Ca and P by developing gilts and sows
- Why limestone is the most important ingredient in the diet
- Can pigs fly – or do chickens say “oink” (Differences in Ca and P digestibility between pigs and poultry)
- Impact of 25(OH)D3 on energy and nutrient digestibility in growing pigs and sows
On July 7th, at the ASAS-CSAS annual meeting, Dr. Su A Lee presented a talk about: “Determination of net energy and nitrogen balance in group-housed pigs fed diets containing varying levels of starch and fiber". Jessica Acosta Ph D Student also gave a talk about: “Greenhouse gas emission, nitrogen balance, and ileal digestibility of amino acids and acid hydrolyzed ether extract in diets containing different inclusion rates of hybrid rye fed to growing pigs”.
Personnel changes
Livia Wang has worked in our Laboratory for almost three years. First as an undergraduate student and for the last 8 month as a full time laboratory assistant. However, she is leaving our laboratory and she will star a new chapter of her life as a Masters student at Cornell University. We wish Livia the best of luck.
