[Reactions of European wild boars (Sus scrofa scrofa L.) to running stress. 1. Behavior of respiratory and heart rate as well as the rectal temperature in standard tests of varying intensity and duration].

Eight wild boars, aged between twelve and six months and weighing between 81 kg and 39 kg, all kept on floor surfaces and diets used also for domestic pigs, were exposed on a horizontally operated belt to three locomotor stresses which differed by intensity and duration. The speeds were 78 m/min in tests A and C and 138 m/min in test B. The time was limited to ten minutes in test A and 40 minutes in test C, whereas in test B the animals were kept running their rectal temperature had gone up to 41.5 degrees C. Rectal temperature, heart rate, respiratory frequency, as well as the electric diastole-systole quotient were measured in each of the tests. Described are the effects of both intensity and duration in terms of disturbance of the physiological equilibrium. The response produced by wild boar were compared with those recorded from domestic swine and yielded only slight superiority in physical fitness of wild boar.
