  • Description: Response of three groups of 12 male creole goats (weighing similar to 10 kg) to environmental variations was tested in Guadeloupe (French West Indies) at three times in the year: the end of the humid season (Oct.-Nov.), the dry season (Feb.-March), and the beginning of the humid season (July-Aug.). Voluntary free intake of banana silage (silage of mixed green banana, bagassa, wheat bran, and urea complemented with molasses) was not significantly affected by climatic variations. Three physiological parameters: rectal temperature, respiratory frequency, and cardiac frequency were measured. These parameters were correlated with heat production-dependent factors such as metabolic body weight, body weight gain, and voluntary free intake. Rectal temperature increased all through the day until sunset, and then decreased during the night. Both minimal rectal temperature and daily increase of rectal temperature were correlated with ambient temperature. Cardiac frequency increased during feeding. Generally cardiac frequency seemed to be correlated with the activity of the animals and so with behavioral response to environmental variations. Respiratory frequency was the most sensitive index of goat response to climate. The daily increase of respiratory frequency was important at the end of the humid season, but was not observed in the dry season. This increase was dependent upon ambient temperature increase, air humidity characteristics, and air velocity. These points are discussed according to integration of those physiological parameters in thermoregulation.
