Research was conducted to compare subcutaneous sites to deep body temperature (DBT) in broilers chickens. The study was conducted in field and lab trials using market age broilers (40-55 days) under summer conditions. Temperature data loggers were surgically implanted in the broilers to record temperatures in the neck, back, and deep body. A logger was also introduced into the upper gastrointestinal tract (UGI) during the lab trials. At the conclusion of the trials, the birds were euthanized and the temperature loggers were retrieved. When the subcutaneous temperatures were compared to DBT, the correlation coefficients were statistically significant (P0.05). In the lab trials, the UGI site was found to be a better representation of DBT than implantation in the lower abdominal cavity. This study shows that subcutaneous sites in broilers can be used as an indicator of DBT.
