摘要: Abstract In fluctuating environmental temperature, homeotherms are able to maintain stable their body which however reveals a rhythmic daily pattern as described in literature. Because of the importance temperature rhythmicity knowledge thermal homeostasis and means facilitate study biological general, aim our was assess influence two different ambient on auricle goat (Capra hircus). For 6 female adult Maltese goats (18 month old), not pregnant clinically healthy were used. On each subject recorded during periods, 7 days each, every 3 hours for 24 hours from 07.00 04.00, at (1st period 18.25 ± 1.48°C, 2nd 28.25 ± 2.05°C). The analysis obtained result under indicates existence periodicity, with small difference...
