Brief Summary of Minutes of Annual Meeting

Brief Summary of Minutes of Annual Meeting

• Welcome, agenda review, NIFA announcements: there were 7 participants in person from 6 stations. Meeting goals were announced, which were updates on NIFA administration and all members, to identify collaborations among institutions. Discussions occurred around ways to make the group more productive, including a multistate publication. The current outline for the group is approved through 2026, so 2025 will be critical for re-working the current tasked items. Lastly, discussion occurred around a lack of human-animal interaction in our tasks, which should be considered for the next edit. A lot of work is not being captured by our current objectives which should be considered.
• Administrative update: Christina Hamilton discussed the structure of multistate groups and fielded questions from members.
• Station reports: Group members provided summaries of NC1029-pertinent research they have conducted in the past year as well as announcements on new facilities, faculty members, and hiring positions.
• Project editor elections: New secretary was elected. Elected member is Jackson Gross (UC-Davis) to the secretary position.
• Next meeting: The next meeting will take place in April in Amarillo, Texas at the School of Veterinary Medicine for Texas Tech University. The group elected to move to the spring in hopes of increasing in-person engagement.

For Objective 1, novel indicators of animal welfare, NC1029 generated new knowledge about non-invasive ways to measure animal welfare.  This is relevant because it allows for more on farm application of welfare. If non-invasive measures can be validated, it allows researchers and farm managers to collect data with minimal disruption to an animal’s life, resulting in a more accurate representation of the welfare state.

For Objective 2, Generating new information to inform animal welfare assessment programs, NC1029 generated practical, farmer accessible information about animal housing on welfare. By understanding the influence of housing on animal development and behavioral repertoire, animal welfare assessments can be fine-tuned to suit animal needs.

Substantial work in being completed which is not captured by these two objectives, specifically in the area of early life experiences.
