Thus, the objective of this study was to investigate the extent to which environmental temperature affects the body weight and cloacal and surface (back, head, wing, and shank) temperatures. The study also investigated the sensible heat loss by radiation of broiler chicks reared at three environmental temperatures (35, 25, and 20°C) up to 7 days of life. The results showed that chicks raised at low environmental temperature (20°C) had lower body weight at 7 days of age. Birds kept at 20°C also had significantly lower cloacal and surface temperatures than did other birds. The most marked difference was seen in the shanks. These findings revealed that body weight declined in chicks reared at 20°C, and radiant heat loss (W) was nine times higher than for the birds kept at 35°C at 7 days of age.
