Accomplishments

Automated measurement of animal responses (Objective 1) 

Researchers at Michigan State University also co-led a research team examining the relationship of social behavior phenotypes to underlying genotypes in pigs with the goal of expanding swine breeding selection programs to include behavior. Similarly, researchers at The University of California, Davis conducted work assessing the development of personality traits in female pigs, the social network of group-housed gestating sows, and gauging the affective state of gilts and sows using cognitive bias testing.

A study by Purdue to evaluate the thermal preference of piglets that have been exposed to various thermal stressors early in life was conducted earlier this year. The aim of this study was to determine if various thermal exposure may aid in those pig’s ability to cope with thermal stressors later in life as well as if it may alter thermal preference.

Researchers at the University of Minnesota validated an ear-tag accelerometer sensor to determine rumination, eating and activity behaviors of grazing dairy cattle. Monitoring behavior can help improve animal welfare by detecting health disorders before they become severe. The results suggested that the sensor accurately monitored rumination and eating behavior; however, active behaviors may be more difficult to record in grazing systems.

Researchers at the Ohio State University have collaborated with researchers at the University of Tennessee and the University of Kentucky to finish the data collection and analysis of a USDA-funded project assessing the effect of short-term sleep deprivation on the immunity and milk production of dairy cows. These results provide the first evidence that a short 24 hours of sleep deprivation can compromise immunity and impair milk production in high-lactation cattle.

Researchers at the Ohio State University and the University of Tennessee have collaborated to finish data collection on a project assessing the natural calving behavior of dairy cows kept on pasture at parturition. As part of the same USDA-funded project, researchers have also begun a project in May 2017 assessing the effect of stocking density and the provision of a secluded area to give birth on the behavior and health of indoor-housed dairy cattle.

Researchers at the University of Minnesota have also investigated performance and welfare of cows on dairy farms with robotic milking systems. It was found, among other findings, that primiparous cows had a lower milking frequency and a higher number of milking failures in early lactation than multiparous cows.

The University of Minnesota in collaboration with Washington State University conducted a study to describe feeding behaviors for preweaned calves in farms with automated milk feeders and investigated the association of those behaviors with management practices. It was found that milk allowance was negatively associated with the number of unrewarded (when no milk is delivered) visits per calf per day. Further data analysis will investigate the association between behaviors and calf health. 

Researchers at the University of Florida are preparing manuscripts for two studies that addressed 1) behavioral responses of weaned heifers to regrouping, and links between cognition and adaptation the group environment, and 2) behavior associated with sickness in the group-housed calf. In addition, we have ongoing data collection from studies investigating behavioral development of calves housed with different degrees of social and environmental enrichment (access to brushes and/or hay, within individual and social housing), and changes in enrichment use following dehorning. 

Researchers at The University of California, Davis conducted work examining wound healing after disbudding with a hot iron in dairy calves. The results provide evidence that these wounds take up to 10 weeks to heal and represent a considerable injury during this time. To begin to understand the subjective states experience during this healing process, we developed and tested a conditioned place preference model for assessing pain in dairy calves.

Researchers at Washington State University conducted two research studies implemented novel technology techniques to investigate how dairy cattle respond behaviorally and physiologically to environmental stress (cold stress and heat stress). The heat stress study specifically measured Holstein calf behavioral and physiological responses during hot weather in two different housing systems. Additionally, one study implemented emerging technology to monitor behavioral changes in dairy cows in relation to their hoof health.

On-farm welfare assessment (Objective 2)

To help inform swine welfare assessments, researchers at the University of Minnesota have compared behavior, skin lesions, tail damage, growth performance, and carcass traits between pigs with docked tails and intact tails. Tail docking reduced tail biting behavior and incidence of tail damage, but did not affect other behaviors, growth performance, skin lesions or carcass traits.

Researchers at the Ohio State University have collaborated with researchers at Iowa State University in the development of a multi-media based training program on timely euthanasia. This educational program developed for swine producers to provide education in timely and humane euthanasia on farm. This project was funded by the National Pork Board. 

Researchers at the Ohio State University finished data collection and analysis on a project assessing veal calf health upon arrival to calf operations in Ohio. The data provides evidence that the health of young veal calves is compromised when they arrive to veal operations, likely due to stress endured during auction and transport. This research will aid in the development of on-farm assessments for veal calves. 

The University of California, Davis, conducted work evaluating the trade-offs and relative reliabilities of animal-based welfare assessment strategies for commercial ducks. Additionally, the group obtained funding to validate the use of commercially available sensors for automated tracking of poultry. An assessment of the variation in housing and welfare related animal based measures was conducted for backyard hens in rural and urban environments. An online training tool was also developed to aid in training auditors (as well as producers and the general public) to assess animal based measures for laying hens. 

Researchers at Michigan State University have published findings comparing how flocks of laying hens of different genetic strains use space and resources differently in aviary housing and completed work on impact of litter substrate on hen behavior in aviaries. They are currently analyzing responses of individual hens and performing risk assessments to understand the relationship between hen physical health and use of space in aviaries. Researchers have begun work with colleagues at University of Bern to understand the impacts of pullet rearing on the behavior and keel damage of laying hens in aviaries. They are also examining the relationship between assessments of hens’ physical welfare, including keel damage, using a standardized assessment (Welfare Quality Protocol) to their behavior to determine what information is captured or absent if standardized physical assessments are used in the absence of behavior by auditing or assessment programs on farm. 

Researchers at the University of Maryland have assessed the impacts of early exposure to ultraviolet light on poultry well-being and behavior and the production and welfare implications for multiple environmental enrichments in production quail. Researchers at Purdue University have conducted studies to examine the effects of stocking density and litter type on footpad dermatitis, feather pecking, and turkey well-being.

Researchers at the University of Florida delivered the 5th offering of the Livestock Education and Certification for Agricultural Law Enforcement (LECALE) training program to provide Ag law enforcement personnel knowledge and skills necessary for assessing the welfare of livestock, with a primary focus on horses and cattle. Their research quantifying phenotypes of startle in response to a novel moving object in young horses is ongoing. In the past year, the University of Florida has initiated research and extension activities focused on the behavior and welfare of horses engaged in equine assisted activities and therapies (EAAT).

Impacts

  1. Michigan State University provides leadership and international expertise on behavior and welfare of hens in alternative housing systems and in detecting and using of behavioral phenotypes to manage and selectively breed group-housed pigs. Station members also train undergraduate, graduate and veterinary students at MSU to assess animal welfare using the collegiate welfare judging competition and via coursework and research.
  2. As part of an international team of collaborators, Michigan State University researchers are also developing novel strategies to capture behavioral phenotypes from pigs in production environments using a combination of visual and sensor technology. Such phenotypic data will facilitate understanding of the genetic basis of social behavior in pigs to further multi-trait genetic selection and improve genetic models incorporating social (indirect) effects. The ability to use automated techniques to gather behavioral data will also further understanding of the role of pig temperament and social behavior strategies in group cohesion.
  3. The multi-media based training program on timely euthanasia created by researchers at the Ohio State University and Iowa State University will be distributed by the National Pork Board, as a service to U.S. swine producers provided by Pork Checkoff. This program will be packaged with other educational material and distributed to swine producers on a national level with the potential to reach approximately 60,000 U.S. swine operations and their employees in the coming years. This innovative tool represents the first interactive euthanasia-specific training program in the U.S.
  4. The collaborative research on dairy cattle sleep (the Ohio State University, the University of Kentucky and the University of Tennessee) has broad implications on the way dairy cattle are housed and raised in the U.S. A majority of dairy cattle are raised in indoor housing that may impact their ability to get adequate rest. Management practices, such as milking 3 or 4 times a day may also have major impacts on the ability of cows to get adequate rest. Our preliminary results will be used to apply for a larger grant assessing the impact of these various management practices on sleep loss and production of dairy cattle.
  5. Research conducted by scientist at the Ohio State University and the University of Tennessee on the behavior of dairy cows at the time of calving is an important step in our understanding of the labor complications and high disease risk in cows after they give birth. The results from this research with provide dairy producers with evidence-based recommendations for how to properly size and design their maternity pens to reduce the risk of labor complications and disease in their cattle.
  6. Purdue’s turkey research has the potential to improve the well-being of commercially raised turkeys because footpad dermatitis is prevalent at all stages of production, and starts as early as 2 weeks of age. Footpad dermatitis becomes more severe as turkeys age. Therefore, any strategies that can reduce footpad dermatitis will greatly improve turkey well-being. In addition, feather pecking results will provide much needed information about how the behavior of turkeys is influenced by stocking density. Based on these results, recommendations will be made to guide the turkey industry in decisions about stocking density and litter management.
  7. Research at Purdue has also focused on piglet mortality; high piglet mortality is a problem in the swine industry and production value is determined by their average daily weight gain while they are piglets. Thermal stress can reduce weight gain but if early life stress has the potential to provide cross-protective effects then it has the potential to improve the well-being of pigs when exposed to an unrelated stressor in the future. Additionally, this early life thermal stress has the potential to alter their range of thermal comfort altering previously accepted ranges of thermoneutrality.
  8. Swine farmers are being asked to transition sow housing from individual gestation stalls to group pens. In the absence of gestation stalls, animals have greater mobility but the establishment of the social hierarchy among group housed sows can result in injuries. Research at the University of California, Davis on distinguishing personality profiles for animals may help to gauge social compatibility of a group, customize environmental enrichment, and provide behavioral predictors of stress vulnerability.
  9. Ducks have received relatively little scientific attention for an animal welfare assessment standpoint. Although duck welfare assessments are conducted in research and production settings, there have been few efforts to evaluate the reliability and accuracy of the welfare assessment protocols used. A scientific comparison of welfare assessment strategies by the University of California, Davis for ducks will not only provide assurances about the accuracy of the assessments, but will allow for benchmarking of the welfare of ducks in relation to management strategies.
  10. Animal based measures of welfare are increasingly being adopted as a means for assessing the welfare of poultry on farm. These measures are often subjective and auditors can have poor reliability within and between assessments. The online training tool developed by researchers at the University of California, Davis for laying hens allows trainees to learn how to assess these measures while testing their reliability. This tool can be accessed by anyone with an interest in this area.
  11. Research from the University of Maryland has resulted in 2 peer reviewed publications, 2 popular press publications and 5 public presentations, as well as one funded research grant. In addition, our station has been invited to report on some of our findings in a webinar to be published in Spring of 2018. Graduate student members of our station have received 2 academic awards.
  12. Results of the work on tail biting at the University of Minnesota will help swine producers understand that stopping tail docking without providing environmental enrichment will cause tail biting among pigs under confinement conditions. Swine producers may predict outbreak of tail biting by monitoring changes in activity levels of pigs and social stress can be measured through social network analysis, and social structures of groups and social positions of individuals may be important to animal welfare. Improvement in the use of technologies such as cow behavior sensors, robotic milking systems and automated feeders for young calves will result in better health, welfare and productivity of dairy herds, contributing millions of dollars to the United States’ economy.
  13. Research at the University of Florida has focused on how housing factors for dairy calves impact behavioral development, cognition, and longer-term behavior and welfare. Data in the past year have contributed to a body of work identifying behavioral indicators which may reflect reduced welfare (behavioral changes associated with sickness, disbudding, and regrouping) and provided some insight into links between cognition and welfare.
  14. Data collected to date from the University of Florida has provided insight into the educational and resource needs of therapeutic horse riding centers. The survey instrument developed could be adapted for wider application regionally and nationally. This initial work in 2017 has fostered collaborations and partnerships within this segment of the equine industry as well as with other units across campus which is providing opportunities to pursue graduate student fellowships and alternate external funding sources for future research.
  15. Teaching and extension activities at the University of Florida have been implemented to improve understanding and awareness of animal welfare topics. In 2017, multiple presentations were delivered on horse behavior and welfare with an emphasis on recognizing and addressing behavioral problems in horses at the Rutgers University Equine Science Center, Horses: Best of the Best Conference, the University of Florida Healthy Horses Conference, the Alabama Farmers Federation Commodity Conference, and the Florida Equine Institute and Allied Trade Show.
  16. Results from projects conducted at Washington State University have been disseminated through presentations (scientific and outreach), factsheets, newsletter articles, lay magazine articles, and exhibits (such as booth exhibits). Presentations targeted a wide variety of audiences that included animal scientists, physicians, veterinarians, and dairy industry representatives.
