Business meeting
•
Albert De Vries (acting Chair and Secretary) called the meeting to order.
•
Based on the advice from Neal Schrick (academic advisor), Albert De Vries will submit a proposal for a new multistate project into NIMMS with the same justification and objectives as was submitted for the rewrite one year ago. Brad Heins and Albert De Vries will take the lead on the rewrite and contact current SCC-84 participants for collaboration on the rewrite.
•
The location of the 2024 annual meeting will be the University of Minnesota with hosts Brad Heins and Isaac Haagen. Tentative dates are October 20 to 22 with a start Sunday afternoon. Intent is to dedicate a portion of the meeting to the pending retirement of Les Hansen (University of Minnesota) who has been a long-term member of this genetics multi-state group.
•
The new Chair is Chad Dechow (Penn State University). He received the Ben McDaniel gavel.
•
The new Secretary is Tasia Kendrick (Michigan State University).
•
Resolutions from the Resolutions Committee (Isaac Haagen and Bailey Basiel):
o
Be it resolved that ... Dr. Heather Huson and her team are to be commended and thanked for a well-planned and informative meeting.
o
Be it resolved that … Aurora Dairy and Department of Animal Science are thanked for an excellent tour and hospitality.
o
Be it resolved that ... We thank our external attendees in-person and virtually, including AGIL, CDCB, and U of Guelph for their attendance and contributions.
•
Other business:
o
The SCC84 listserv is managed by Li Ma (U of Maryland) and needs to be expanded to include USDA-ARS-AGIL, CDCB, University of Guelph. De Vries and Huson action.
o
If a full multi-state project is in place for the next annual meeting, a template annual report should be completed by each participating organization to collect the necessary data that needs to be reported to NIMMS. See the NC2042 template report, for example. De Vries and Kendrick action.
o
Heather Huson will contact Nicolas Lopez-Villalobos (Massey University) to investigate the feasibility of holding the 2025 meeting in New Zealand
