title: [The role of external respiration and blood circulation in heat emission during exposure of Taurotragus oryx canna antelopes to solar heat].
abstract: Experiments have been made on 4 elands at the age of 3--4 months, mean body weight 78 kg. At ambient temperature 31.5degrees combined with solar radiation, polypnoe was observed in the animals. Under these conditions, only small changes in the body temperature were observed, although skin temperature became 4--6degrees higher than in the morning. Heat production was 10% lower than that at 22.5degrees. The animals eliminated about 8% of metabolic heat through respiration in the morning and about 7%--in the afternoon.
