Abstract
Thirty-two West African dwarf goats were exposed to temperature treatments: 20, 25, 30, 35, 35, 35, 30, 25, 20°C each lasting three days.
Sixteen goats were kept in individual pens (“I”), the others in two group pens (“G”). Heat production (HP) and activity were recorded during 48 hours in each temperature treatment.
Mean HP and ME intake were similar for “G” and “I” animals, but “I” animals had lower values than “G” animals at low chamber temperatures and higher values than “G” animals at high temperatures. Upper critical temperature was between 25°C and 30°C under an increasing T and between 30 and 35°C under a decreasing T. Adaptation of heat production and ME intake to a change in temperature of 5°C required at least six and possibly more than nine days.
Diurnal variation in HP was large, up to 44% between extremes. This was largely due to variation in activity.
