Congratulations to 2022 NMC Research Poster Presenters
The National Mastitis Council (NMC) Research Committee accepted 37 research posters for the 2022 Technology Transfer Session (TTS), being held in conjunction with the 2022 NMC Annual Meeting. Researchers recorded summaries of their research, which will be available to in-person and virtual NMC Annual Meeting registrants on a micro website. Meeting registrants will receive an e-mail about how to access these recordings.
In addition, the first 10 posters (listed below) will be presented during the Research and Development Summaries Session, set to start at 2 p.m. Pacific time on Feb. 2. The complete list of TTS papers, authors and their affiliations is shown below.
