This year was the third iteration of this meeting, hosted for the first time by Christensen Farms. Guests were invited to tour either the feed mill or the truck wash located in Sleepy Eye before sitting down for a day of productive exchange.
After a short presentation by the host company, Deans Brian Buhr and Trevor Ames gave an update on the main initiatives from their respective Colleges. Dean Ames introduced the latest AGREETT faculty hires, Noelle Noyes and Declan Schroeder, as well as the anticipated arrival of Dr. Matheus Costa in the new year. The 2+2 program in collaboration with South Dakota State University was received with enthusiasm by the swine producers.
After lunch, attendees were divided into groups to brainstorm research ideas in four main areas: swine nutrition, swine health, manure management, and swine production and housing. After two hours of spirited discussion, 15 researchable questions were identified as the most pressing problematics faced by the Minnesotan pork industry. The meeting left the researchers inspired to keep offering science-driven solutions, and all agreed to meet again in 2019.
In this final episode, Dr. Montserrat Torremorell (University of Minnesota), Dr. Amy Vincent (USDA Agricultural Research Service), Dr. Christa Goodell (Boehringer Ingelheim), Dr. Gordon Spronk (Pipestone Veterinary Services), and Dr. Tom Wetzell (Boehringer Ingelheim) discuss the control of IAV-S, the research & development of vaccines for IAV-S, and the products that are being developed from the research.
Our new contribution to the National Hog Farmer was written by Dr. Talita Resende, a PhD candidate at the University of Minnesota under the supervision of Dr. Connie Gebhart. Talita’s research focuses on swine ileitis and models to better understand its pathogen: Lawsonia intracellularis. Today, she explains how she uses enteroids.
The small intestine is largely responsible for nutrient digestion and absorption in the gastrointestinal tracts of pigs, but it is also an ideal colonization site for enteric pathogens. The investigation of the interactions between host and enteric pathogens can be conducted in vivo, or in vitro, with advantages and disadvantages for each of the models. Enteroids, small intestinal organoids, represent a new in vitro approach to investigate those interactions. But why are enteroids a new approach and what are their advantages in comparison to the current models?
Enteroids are three-dimensional structures originated from embryonic stem cells, induced pluripotent cells or adult stem cells from intestinal tissue. Therefore, they present all the cell types and a structural organization similar to crypts and villi found in the small intestine. This complex structure offers ideal conditions to investigate the mechanisms by which Lawsonia intracellularis causes proliferative enteropathy – also known as ileitis – in pigs.
