Immunology of Beef Stocker Cattle

Area of Science:

• Veterinary immunology
• Animal science
• Stocker cattle health

Background:

• Inflammation and immunity in stocker cattle are critical research areas.
• Stocker cattle undergo rapid immunological shifts during stressful transitions like weaning, transport, and commingling.
• These stressors activate neuroendocrine pathways and systemic inflammation while suppressing innate immune functions.

Purpose of the Study:

• To define the immunological transitions in stocker cattle.
• To understand the impact of stress on immune function in stocker cattle.
• To identify high-risk periods for disease susceptibility.

Main Methods:

• Review of current evidence on stocker cattle immunology.
• Analysis of immunological transitions during stressful events.
• Correlation of immune status with disease outcomes.

Main Results:

• Stressful events trigger neuroendocrine and inflammatory responses.
• Protective immune functions, particularly innate immunity, are depressed.
• A high-risk period for disease susceptibility is identified, influenced by viral/bacterial exposure and host response.

Conclusions:

• Stocker cattle immunity is dynamic and highly sensitive to stress.
• Immune suppression during stress creates a window for disease development.
• Further research is needed to mitigate disease risks in stocker cattle.
