64. Adoption of Research-based Stockmanship Practices to Reduce Stress and Improve Welfare, Health, and Productivity in Beef Production Systems.

Abstract Caregiver behavior and stockmanship practices represent critical components of beef production systems that influence cattle health, performance, and wellbeing. Stockmanship approaches grounded in understanding cattle behavior, including acclimation to human presence and guidance during routine management events, can alter how cattle respond to environmental and management stressors. Human interactions during events such as weaning, processing, transportation, and pen movement represent repeated opportunities to establish trust and promote confidence, which are associated with improved biological function and production outcomes. Cattle exposed to consistent, positive human interaction demonstrate behavioral patterns indicative of increased confidence, including willingness to approach feed and water sources, engage in social and exploratory behaviors, and move voluntarily through handling systems. These responses facilitate efficiency of routine management procedures and reduce expression of defensive behaviors. Cattle that are confident in human presence are also more likely to express early indicators of morbidity, enabling timely identification and intervention for conditions such as bovine respiratory disease and lameness. In contrast, cattle with negative or inconsistent handling experiences may mask early clinical signs and exhibit avoidance or flight behaviors, potentially delaying diagnosis, impairing treatment success, and prolonging recovery. Stockmanship methodologies that emphasize handler purpose, position, posture, and appropriate application of pressure and release promote voluntary cattle flow and reduce reliance on force-based handling. These approaches encourage maintenance of normal behavioral patterns, including feeding, resting, rumination, and exercise, which are associated with physiological homeostasis. Positive human–animal interactions are also associated with reduced activation of stress-related endocrine pathways, minimizing cortisol release and mitigating stress-induced immunosuppression. In turn, cattle are better able to cope with routine and acute stressors and return to a productive physiological state more rapidly. Collectively, implementation of consistent, behavior-based stockmanship practices enhances cattle confidence, facilitates early disease detection, and supports physiological stability, which are associated with improved health and performance outcomes. These concepts highlight the importance of caregiver skillset, consistency, and understanding of cattle behavior as key drivers of productivity and efficiency in beef production systems.
