This book examines the scientific principles and practical methods used in sampling for animal disease surveys, emphasising the importance of accurate data collection in veterinary epidemiology. It explains how systematic sampling techniques support the detection, monitoring, and control of diseases within livestock populations. The discussion highlights the role of epidemiological investigation, diagnostic services, and risk evaluation in identifying disease outbreaks and understanding patterns of transmission. Attention is given to the planning of disease surveillance programmes and the use of statistical sampling approaches that ensure reliable and representative information. The book also considers the significance of coordinated control measures, public awareness initiatives, and preventive strategies in reducing the spread of infectious diseases. By integrating epidemiological theory with field-based veterinary practices, it demonstrates how well-designed sampling and survey systems contribute to effective disease management and the protection of animal health.

The work encourages a systematic understanding of disease surveillance and risk assessment within livestock systems. It supports advanced learning in veterinary epidemiology, animal health management, and disease monitoring programmes used in modern agricultural and veterinary practice.
