**5. Conclusion**

This chapter provided, through a large number of examples, a comprehensive overview of the use of biotelemetry in poultry production. The chapter outlined the types of equipment that are commercially available as well as those adapted and developed by researchers for use in poultry production research. Many poultry biotelemetry studies were aimed at validating new commercially available telemetry systems and measurement techniques and have clearly demonstrated their effectiveness for accurate continuous monitoring of poultry physiology. The majority of these studies were concerned with the monitoring of deep body temperature. Biotelemetry has been successfully used in a wide range of research pertaining to poultry production. Many studies were concerned with monitoring and evaluating physiological and behavioral responses of poultry under various stressful environmental stimuli and management conditions to (1) gain a better understanding of poultry thermoregulatory responses; (2) improve management practices; and (3) evaluate the effectiveness of various environmental conditions. Continuous biotelemetry monitoring of poultry provides dynamic responses that define relationships with environmental variables. These relationships have been described using mathematical models constructed to predict future outcomes for a range of inputs. A pioneer study used biotelemetry to design an environmental controller which maintains poultry deep body temperature, under stressful ambient temperature conditions, below a given threshold by controlling air velocity rates. This study is the first step in designing the future poultry environmental controller which responds directly and in real time to the birds' physiological responses.
