Developing a model to promote caretaker confidence and communication in treatment decisions for dairy cattle through case studies.

The significant role of dairy caretakers in maintaining animal welfare on dairy farms emphasizes the necessity of appropriate training and education to ensure the implementation of practices that promote good animal welfare. This study explored the potential of case-based learning as a novel approach to training for dairy caretakers by investigating dairy caretakers' perspectives on case study discussions. Additionally, this study sought to understand thoughts and feelings of caretakers during case study discussions to help identify information that caretakers use to evaluate cases and make decisions.

Frequency of disagreements between producers and veterinarians about pain management in cattle.

Pain management is a key element of ensuring animal welfare. Although the opinions of both producers and veterinarians affect decisions about the use of pain mitigation on cattle operations, little is known about how they communicate about this topic. Given the importance of a veterinary-client-patient relationship for developing pain mitigation protocols, understanding the communication between veterinarians and producers is key to the implementation of robust, industry-wide pain management protocols.

A Nationwide Survey of Animal Science Students' Perceptions of Animal Welfare across Different Animal Categories at Institutions in the United States.

Animal welfare is an increasingly important topic across multiple academic disciplines; however, few studies have investigated student perceptions of animal welfare outside of veterinary medicine. The objective of the study was to evaluate animal science students’ perceptions of animal welfare to determine if perceptions differ across animal categories. An online survey was distributed to animal science programs at institutions across the United States.

Preliminary Exploration of Weekly Peer Group Discussions as a Strategy for Coping with Feelings Associated with Euthanasia in Dairy Caretakers.

Dairy caretakers experience a variety of occupational risks including stress related to performing euthanasia and making euthanasia-related decisions for cattle in their care. Few supportive interventions exist to help caretakers cope with euthanasia-related stress. The aim of this study was to assess the impact of weekly peer discussion sessions as an intervention to reduce euthanasia-related stress and grief in dairy caretakers.

Perceptions of animal welfare and animal welfare curricula offered for undergraduate and graduate students in animal science departments in the United States.

While perceptions of animal welfare have been assessed in veterinary students and students internationally, there remains a gap in research concerning undergraduate and graduate student perspectives of animal welfare in animal science programs at colleges and universities across the United States. A survey was developed to assess current animal science student perspectives of the importance of animal welfare as part of their education, their knowledge of available educational opportunities, and resources they think should be included in animal welfare curricula. An online survey was distributed to a national listserv of university administrators of animal science programs in the United States.

Unmitigated Surgical Castration in Calves of Different Ages: Cortisol Concentrations, Heart Rate Variability, and Infrared Thermography Findings.

The objective was to characterize physiological responses to unmitigated surgical castration in calves of varying ages. Thirty male Holstein calves of three ages [<6 w (6W); 3 m (3M); 6 m (6M); = 10] underwent a simulated castration treatment (SHAM) followed 24 h later by castration (CAST). For both treatments, heart rate variability, eye temperature, and cortisol were measured over time from treatment to specified end points to capture the acute response period.

Characterization of Fed Cattle Mobility during the COVID-19 Pandemic.

The COVID-19 pandemic had significant consequences on cattle slaughter capacity in the United States. Although industry stakeholders implemented strategies to minimize cattle welfare impacts of increased weights, days on feed (DOF), and increasing temperatures, there were concerns that mobility challenges would be observed at slaughter facilities. The objectives of this study were to characterize mobility in fed cattle during this recovery period and to identify factors impacting mobility.

Unmitigated Surgical Castration in Calves of Different Ages: Electroencephalographic and Neurohormonal Findings.

Castration is a common management procedure employed in North American cattle production and is known to cause a pain response. The present study was designed to investigate the effect of unmitigated surgical castration on the electroencephalography (EEG) responses and plasma substance P (SP) concentrations in calves of different ages under the same experimental conditions. Thirty male Holstein calves in three age categories [<6 weeks (6W); 3 months (3M); 6 months (6M); 10 calves per age group] were used in the study.

Dairy Caretaker Perspectives on Performing Euthanasia as an Essential Component of Their Job.

The objectives of this study were to identify caretakers' perceptions and stressors related to performing on-farm euthanasia as well as potential ideas for intervention strategies to alleviate negative effects of performing euthanasia on caretaker well-being. Additionally, we aimed to determine how euthanasia methods, procedures, and training correlate with dairy caretakers' attitudes toward performing on-farm euthanasia and their job satisfaction and sense of well-being. Thirty-eight dairy caretakers (19 workers, 15 supervisors, 3 owners, 1 veterinarian) participated in focus groups or interviews conducted and recorded on five Northern Colorado dairies.

Intraobserver and interobserver reliability of mud scoring systems for use in cattle at slaughter.

At slaughter plants, live cattle are often scored for mud coverage as mud on hides can impact food safety and drives decisions regarding interventions during processing. Currently, there is no standardized method utilized to assess mud coverage. The aim of this study was to determine the intraobserver and interobserver reliability of 3, 4, and 5 point mud scoring systems.
