Name: Turkey Heat Balance Study Parameters Description: This schema describes the variables in a dataset collected from several studies on growing turkeys. The data include information on the housing environment, bird characteristics, body temperature, and heat production and heat loss. Measurements are taken from individual birds over time under normal temperature conditions and during chronic heat stress. The goal of this schema is to clearly explain each variable so the data can be understood, compared across studies, and reused in future research.
