Accomplishments

See attachment   Impact Statement Summaries Animal welfare is affected by a multitude of dynamic, fluctuating physiological and external environments. The effect of several of these factors on animal welfare are well known, yet limited scientific evidence exists in some areas more than others.  Development of outcome-based measurements for welfare assessments. Research efforts were targeted to develop novel welfare assessment criteria (e.g., behavior, resource use) and strengthen the scientific support of currently utilized welfare assessment tools or housing recommendations (e.g., stocking density).  Development of cognitive bias testing evaluation strategies.  Emotional (affective) states are difficult to quantify and can range from negative, to neutral, to positive. Research efforts have been deployed to develop strategies for cognitive bias testing methodology for poultry, especially broiler chickens, and swine. Quantifying behaviors indicative of stress, disease, pain, and aggression.  Members are generating knowledge on the gastrointestinal physiology of horses with a history of oral stereotypic behavior and sheep attachment and stress related behavior. Changes in genomic markers and  social behavior are an indicator of welfare (disease/pain) in dairy calves as well as group-housing aggression and heat stress in pigs. Impact of environment and management practices on animal welfare. Members are evaluating the effect of environment (lighting and environmental enrichment) on swine welfare in farrowing stalls, the role of enrichment on poultry, cattle, and goat welfare, and the benefits of exercising horses at a young age. Euthanasia research is important to ensure animals are killed humanely. Research evaluating behavioral and physiological indicators of poultry welfare during cervical dislocation and stunning and has indicated that decapatation during cervical dislocation does not impact broiler welfare during euthanasia and that stress hormones do not exhibit the same response patterns during electrical and carbon dioxed controlled atmsphereic stunning methods. The use of precision livestock tools is ubiquitous throughout the membership.  Precision livestock farming is the future of animal agriculture and is critical to monitoring animal welfare and promoting sustainability.  Long-term goals are to create evidence-based recommendations for the sustainable use of precision technologies for horse therapy programs and on dairy farms, with focuses on improving animal welfare assessment and individual animal management on-farm using precision technology data.  Specific projects emphasizing precision technology investigated the economics of dairy calf raising and benchmarking tools at the farm level.  Decision support tools will help dairy farmers understand decision economics and make more informed decisions toward improved profitability. Technology research provides new insight into the utility of automated temperature monitoring.  Decision support tools will help dairy farmers understand decision economics and make more informed decisions toward improved profitability. Finally, good animal welfare is paramount to the dairy industry, including producers, processors, distributors, and cooperatives. The development of a new, accurate, and remote welfare assessment benchmark using validated multi-variable precision dairy technologies (PDTs) has the potential to increase the sustainability of the dairy industry.

Impact Statements

The use of precision livestock tools is ubiquitous throughout the membership. Precision livestock farming is the future of animal agriculture and is critical to monitoring animal welfare and promoting sustainability. Long-term goals are to create evidence-based recommendations for the sustainable use of precision technologies for horse therapy programs and on dairy farms, with focuses on improving animal welfare assessment and individual animal management on-farm using precision technology data. Specific projects emphasizing precision technology investigated the economics of dairy calf raising and benchmarking tools at the farm level. Decision support tools will help dairy farmers understand decision economics and make more informed decisions toward improved profitability. Technology research provides new insight into the utility of automated temperature monitoring. Decision support tools will help dairy farmers understand decision economics and make more informed decisions toward improved profitability. Finally, good animal welfare is paramount to the dairy industry, including producers, processors, distributors, and cooperatives. The development of a new, accurate, and remote welfare assessment benchmark using validated multi-variable precision dairy technologies (PDTs) has the potential to increase the sustainability of the dairy industry.

Brief Summary of Minutes

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.

Accomplishments

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.

Impact Statements

Developing non-invasive indicators of welfare can be useful on farm, in clinic and in zoos. Research exploring non-invasive methods of welfare including behavior, thermal imaging, heart rate variability, breed specific concerns and so forth can help producers understand welfare of animals in the moment. Cognitive bias testing is on the rise as a way to measure negative and positive affective states in poultry. Using radiography and tomography could assess keel bone and general bone health in poultry, leading to better welfare. Work is underway to find non-invasive ways to assess horses for gastric ulcers; currently, the only available method includes sedation and scoping, which is costly and time consuming.

Brief Summary of Minutes

Reviewed Current Objectives:

Conversation about word selection in the objectives and to potential re-imagine the structure of the next research program:

People tend to use the word “welfare” which can be narrowly defined as health. The Animal Welfare Community continues to more broadly define the term

Additional questions have been brought up around the inclusion of companion animals with farmed animals particularly those as service or animal source protein.
Considerations for next iteration of objectives to take a more holistic approach to the 5 Domians beyond growing animals and good health.
Additional comments to ensure this group remain distinct from other groups that may have more of a health focus.

Group project interaction:
How to create a more interactive group project. Over time the group has gotten farther away from collaborative activies.

Discussions about developing joint research proposals between institutions.
Discussion around analyzing data sets between partner institutions.
Questions around using a list serve or app such as slack to increase ommunication. Could the secretary take on an additional role in communication. Other collaborative tools such as TEAMS in Microsoft.

Further discussion about collaborative activities across the region based on USDA directives and do we have a functional group since this topic is a multispecies group which makes it difficult to collaborate around topics?

Potential thoughts
- Create a white paper to build collaboration
- Joint workshops, education or extension activities
- big lift concerning the rewrite which is large demand of time, does the benefits outweigh the cons.

Value added activities
-Career and Professional development for faculty, staff and students
-Zoom based mid year research symposium
-Mini workshops
-Needs assessment
-Gap analysis
-Navigating the consulting space as faculty

Hosting next meeting:
Some consideration for a joint meeting with the North American ISAE meeting to occur in Guelph. No clear discussion on best timing for a meeting.
UC Davis is expected to host/coordinate the next meeting.

Thoughts around continuing to participate in field trips during annual conference? What about a virtual mid-year activity?
Or a joint international meeting to meet with other scientists and/or experience how other countries approach animal welfare.
Questions concerning group participation and attendance. Discussed establishing a 3 yr rule and keeping attendance. Needed additional guidance from USDA. Recommendation from Kristine Hamilton USDA was to inform them of lack of attendance.

Accomplishments

Station: Michigan State University Researchers Janice Siegford, Professor and Associate Chair (station representative) Madonna Benjamin, Associate Professor Jackie Jacobs, Assistant Professor Daniel Morris, Associate Professor Janice Swanson, Emeritus Professor Primary research interests as they relate to NC1029 objectives Research from Multistate Project NC-1029 Applied Animal Behavior and Welfare is critical to provide the science and technology to help stakeholders, including those in the agricultural sectors, education and at the global level, make informed decisions about standards of animal care. For example, understanding how much space a hen actually uses and when and how often she needs to perform behaviors using specific resources or types of space facilitates transition to cage-free housing systems that meet societal requirements while truly enhancing welfare by allowing hens behavioral freedom. Similarly understanding how to prevent problems such as floor laying without reducing welfare when cage-free systems are implemented is critical to creating a system that balances animal quality of life with producer constraints. Collaborative research is underway to address these questions with NC1029 multistate member Ahmed Ali of Clemson. A complementary collaboration with Daniel Morris (MSU) and Ahmed Ali (Clemson) is examining whether computer vision and machine learning can be used to detect and deter piling behavior in cage-free laying hens. Impact statement for primary NC1029 research in the past year (10/1/2023-6/30/2024) Data was collected from ~5,000 cage-free laying hens housed in 2 aviary styles managed using different strategies to prevent hens from laying eggs on the floor as part of a NIFA AFRI grant to Clemson (A. Ali) and Michigan State (J. Siegford) and two additional grants from the Michigan Alliance for Animal Agriculture to J. Siegford and D. Morris (both MSU) with A. Ali (Clemson) collaborating on both. Preliminary data related to egg quality was presented at the International Scientific Forum in January 2024. Age-related changes in egg quality were observed consistent with previous research. Neither aviary style nor management to reduce floor laying impacted egg quality, indicating that changes that housing systems that provide hens with access to additional space and resources or that attempt to guide laying behavior will not have negative consequences on egg quality. Two Master’s students (X. Ma and K. Baugh), one PhD student (Y. Long), one postdoc (V. Bongiorno), and one undergraduate (E. Gregas) at MSU are researchers on the cage-free laying hen projects and have gained experience conducting research, analyzing data, presenting their findings and collaborating with colleagues at Clemson and Guelph. Six additional undergraduate students and 2 technicians provided assistance managing hens and collecting data and were trained regarding low stress handling, hen husbandry, scan sampling, fear tests, and data recording and entry. Future research related to NC1029 Data related to egg production, location of egg laying, welfare quality parameters, and activity of hens housed in two styles of cage-free aviaries are being analyzed and will be presented at the Poultry Science Association meeting in July 2024 and then shared with industry stakeholders and published as peer-reviewed science. Results of the computer vision and machine learning study will be presented at the 11th European Conference on Precision Livestock Farming in September 2024 and will serve as preliminary data for a USDA AFRI submission. Video will be decoded and additional data related to hens’ distribution in the system, fear responses, and behavior on litter will be analyzed in the coming year. MS students will complete research related to fear responses and activity in the cage-free environment. Additional research projects related to space used to wing flap and behaviors performed on the litter will be carried out by a postdoc and team of undergraduate researchers.

We are conducting research to develop non-invasive strategies for identifying sick cattle using canine olfaction. We are using computer vision, big data analytics, and sensor output to characterize behavioral phenotypes relevant to cows that are thermotolerant. WE are conducting startle tests on these animals to determine the physiological relationship between the serotonergic system and the startle response. Station (University/Organization) North Dakota State University Researcher(s) (Name, Title) Christopher Byrd, Assistant Professor of Swine Research and Teaching Primary research interests as they relate to NC1029 objectives Animal welfare science, stress physiology, applied ethology Impact statement for primary NC1029 research in the past year (10/1/2023-6/30/2024) My laboratory continues to focus on developing physiological stress measures and evaluating methods for mitigating stress on farm. Between 10/1/2023 and 6/30/2024: We are currently determining whether ultra-short HRV recordings are appropriate for use with sows housed individually and in groups. We are studying leukocyte coping capacity (LCC) as a potential rapid measure of swine physiological stress. Other ongoing studies include the development of oleic-acid-containing oleogels for reducing pain and improving wound healing in piglets following surgical castration, and the effect of air quality on physiological and behavioral measures used to detect swine stress. Future research related to NC1029 Pain mitigation via oleogels – Oleic acid oleogels to reduce pain and improve wound healing following surgical castration in piglets.

Station (University/Organization) Auburn University Researcher(s) (Name, Title) Bethany Baker-Cook, Assistant Professor Dianna Bourassa, Associate Professor / Extension Specialist (Station Head) Primary research interests as they relate to NC1029 objectives Dr. Baker-Cook’s research interests are poultry welfare and behavior. Using behavioral and physiological indicators of animal welfare to understand welfare in early life and how this impacts long-term welfare, behavior, and productivity. As well as using behavioral and physiological indicators to improve the welfare of broiler breeders. Research to improve welfare at end of life (euthanasia, slaughter) to strengthen welfare assessments and standards. Dr. Bourassa’s research interests are poultry processing, specifically the use of physiological indicators of animal welfare to understand and optimize methods during poultry harvest and slaughter. Impact statement for primary NC1029 research in the past year (10/1/2023-9/25/2024) Dr. Baker-Cook collaborated with Dr. Bourassa evaluating behavioral indicators of animal welfare to assess the impact of decapitation during cervical dislocation. Based on the results, decapitation during cervical dislocation does not impact broiler well-being during euthanasia. Dr. Baker-Cook is working on research that looks at behavioral development and sequences in early-life for chicks and turkeys. This knowledge of normal behavioral development and behavioral sequences for birds raised in commercial settings will help understand deviations in behavior due to poor well-being and health, can be used in the future for research and by farmers to assess bird welfare and health Dr. Baker-Cook is currently researching the impact of natural light through windows on broiler welfare and behavior raised to 53 days. This research has shown that natural light improves food pad dermatitis. Dr. Baker-Cook did research on repeated exposure and movement on the fear responses. It was found that repeated exposure to fear tests, either on the same day or over time, reduced the fear response. Furthermore, the test also encouraged play. Dr. Bourassa and Dr. Baker-Cook are currently collaborating on a study comparing potential physiological indicators of welfare impacted by broiler lairage temperatures coupled with carbon dioxide controlled atmosphere stunning methods. Results indicate that low lairage temperatures result is an increase in pO2 and sO2 in blood. Lairage temperatures prior to stunning did not impact following stunning. However, carbon dioxide controlled atmosphere stunning impacted multiple blood metabolite parameters. Future research related to NC1029 Using behavior and physiological indicators to understand the impact of early-life environment on bird welfare (hatchery, transport, and brooding). Using behavior and other indicators to understand the impact of natural light in broiler production. Using behavior and other indicators to understand the impact of group size and spiking on broiler breeder welfare, fertility and hatchability. Understand enrichment usage in broiler breeders. Using behavior and physiological indicators to understand the welfare at end-of-life with stunning. Station (University/Organization) University of Arkansas Researcher(s) (Name, Title) Shawna Weimer, Assistant Professor Primary research interests as they relate to NC1029 objectives • Develop new and apply existing measures to generate novel knowledge or applications and strengthen the scientific basis of poultry welfare assessment criteria. Impact statement for primary NC1029 research in the past year (10/1/2023-6/27/2024) Animal welfare is affected by many dynamic, fluctuating physiological and external environments. Many of these effects on animal welfare are well known within the animal agriculture industry, yet limited scientific evidence exists in some areas more than others. Thus, the research in the Weimer lab is targeted at evaluating new and existing genetics, resources, and husbandry methods that affect poultry welfare. Future research related to NC1029 The Weimer lab will focus on investigating key management practices that impact poultry welfare. Upcoming research projects include exploring the effects of monochromatic lighting during incubation and growout, assessing the influence of environmental enrichments on the behavior of commercial turkey hens, and evaluating the use of sprinklers to improve the behavior and welfare of commercial broilers. Station (University/Organization) Oregon State University Researcher(s) (Name, Title) Monique Udell, PhD, CAAB, Associate Professor, Animal & Rangeland Sciences Primary research interests as they relate to NC1029 objectives Integrating, translating and validating assessment methods, tools and technology used in some settings (e.g., companion animal settings or zoo to production animal settings or vice versa) for use in different fields or with a more diverse range of species. The aim is to validate and expand access to evaluation tools that can be used to improve animal welfare and/or behavior assessments in applied settings. I am also interested in cross-species comparisons of behavior. Social development and cognition- evaluations aimed at measuring how different environments and experiences may alter animal social development, behavior, or cognition in ways that impact welfare or productivity. And measurements of how external or contextual variables may influence human/caretaker perceptions of animal welfare or behavior. Research on bonding and attachment, both with conspecifics and humans, as an indicator of welfare, quality of human-animal interactions and stress resilience in captive/production settings. To develop/evaluate tools and procedures that would allow for effective, efficient, and less invasive handling or sample collection – with a special emphasis on methods that can be used to detect and/or reduce stress and improve wellbeing non-invasively. For example, research on the use of hand-held thermal cameras for detection of stress or employing low stress training techniques and assessments to achieve management or research goals. Main species of interest include sheep, dogs, cats and captive wildlife. I also have some experience and interest in work with horses and swine. Impact statement for primary NC1029 research in the past year (10/1/2023-6/30/2024) This year I have continued work on sheep, dog and cat attachment and cross-species bond assessments as a measure of human-animal interaction quality and a predictor of stress and stress reliance in animals, leading to 3 new publications and 2 in prep. One of these studies was in collaboration with researchers at Purdue University (Dr. Candace Croney’s lab). I have continued to engage in several research projects looking at domestic cat stress, welfare, care practices. This work included cross-state collaboration (with researchers located in Indiana, Maine, and California), international collaboration (with researchers in Canada, Japan and Uruguay), and multi-state industry collaborations. I have continued work in human perception of animal behavior and welfare, evaluating how human emotions, beliefs and contextual factors may influence perception of animal behavior and welfare. This work is critical to understanding how external factors may influence welfare and behavior assessments (both formal and informal) that rely on human perception or caretaker reports. We are about to submit our first paper on this topic (focused on cats) and have begun to expand this work to new species including rabbits. The work on perception of rabbit welfare will be associated with a PhD thesis by a student in my lab (Amanda Puitiza). We have begun work developing and validating a new stress assessment that aims to be user friendly and a robust predictor of chronic and situation stress in animals. The initial survey and validation will focus on dogs, but we have plans to expand to other species in the future. This work will be part of a PhD thesis by a student in my lab (Alisa Tananaeva). This year I also served on the Morris Animal Foundation Equine Behavior Scientific Advisory Board, which assists with evaluating research priorities and the research proposal review process. I have collaborated with and/or provided research guidance to multiple industry partners in other states including Blue Buffalo (MN) and Hill’s Pet Nutrition (KS), and I have served on thesis committees of graduate students located in other states including Boise State (ID), Purdue University (IN) and Arizona State University (AZ). Future research related to NC1029 Applying and evaluating secure base, attachment and sociability assessments to (1) understand factors that influence animal social development and attachment, (2) to validate new approaches to measuring the quality and outcomes of conspecific and cross-species interactions, and (3) to evaluate the impact of human-animal interactions on stress resilience, welfare and cognitive performance in animals (sheep, dogs, cats and other species). Translation and validation of behavior and welfare methods from captive and companion animal settings to production animal settings with the aim of increasing accessibility, lowering cost and improving animal welfare outcomes across settings. Investigation of new behavior/cognitive measures that could inform our understanding of animal welfare in applied settings, as well as factors that influence and improve these outcomes (e.g. Stress Level Questionnaire) Research aimed at understanding how human emotion, beliefs and context may influence responses on animal behavior surveys and alter perception of animal emotions, behavior or welfare. Evaluating implications for welfare assessment design and understanding how such factors may impact animal management practices. Station: Texas Tech University Researchers Nichole Anderson, Assistant Professor Primary research interests as they relate to NC1029 objectives Researched performed in accordance with the objectives of NC1029 and in collaboration with other members of NC1029 included work with Chris Byrd at North Dakota State University. Work included continued efforts to publish the final manuscripts of a multiyear project. The project focuses on the use of a virtual reality learning module to help teach animal welfare to students. The primary emphasis is on swine and dairy production. This contributes to objective 2, as it continues to strengthen the possible field of future animal welfare assessors and helps measure the effectiveness of teaching animal welfare assessment to others. Future research related to NC1029 Emphasis at the TTU station is moving towards developing indicators of animal welfare in horses involved in equine assisted service programs. Additionally, continued work is underway to secure funding to continue developing and testing online learning modules, specifically designed to be used in veterinary medical education.
