This research aimed to investigate the influence of sheep’s coat color on heat toleranceftorage, intake during the and performance of Santa Inês breed. The experiment was conducted in summer season at the Agreste region of Pernambuco State, Brazil.It was used a split-plot amangement in a complete randomized experimental design for the following response variables: retal temperature, respiration rate, body surface and skyn temperature. These measurements were performed both during the morning and afternoon. Sweating rate was measured in the afternoon. Heat tolerance index of the animals was avaliated weekely in a completel randomized design. Forage intake was estimated. The environment was monitorated daily by a meteorological station installed close to the experimental paddock and the thermal confort index was calculated. White sheeps showed a small superiority their heat tolerance than the others but his performance did not differ from sheep with chestnut and black hair coat colors.
