General prediction equations were developed for production variables of tom turkeys, including: daily rate of gain, daily feed energy intake, and body heat loss. The predictions depend on both weight and temperature. The current national data base (39 million toms) was used to develop the weight dependency of these variables. The temperature dependency was modeled using data from the literature and integrator supplied data from North Carolina. Results indicated that rate of gain was highly dependent on temperature and current body weight, while feed conversion efficiency was negatively correlated with air temperature, and highly variable.
