A proposal to apply operative temperature for the evaluation of thermal conditions in the broiler living zone

Summary

The paper presents results of temperature measurements at the level of birds’ heads, at the level of bedding under the birds, and in areas not occupied by birds, as well as measurements of optimal air temperature and the distribution of the calculated operative temperature in the course of a production cycle conducted in real life conditions of a mass scale production. The concept of operative temperature (Θ₀) was used to evaluate thermal conditions in the broiler living zone. It was calculated as an arithmetic mean of indoor air and litter temperatures.

The application of operative temperature for the evaluation of thermal conditions in the broiler living zone seems to be adviced as it extends the scope of physical parameters to be monitored by the temperature of litter surface and provides data necessary to monitor and regulate litter temperature or reduce stock density in order to prevent thermal stress or discomfort.
