To elucidate a possibility of the participation of sensory-psychological pathway to respond to the stressors at the starting phase of transportation, a swing model experiment and real transportation were conducted using three naive male Tokara goats with indwelling catheters installed in jugular and femoral veins. With the swing model experiment, the caged goat was exposed to 6 repetitions of a module of 15 min constituting 10 min of irregular and intense movements and 5 min of regular movement. With the real transportation the caged animal was loaded on a truck and journeyed along the highway for 3h. During the swing movement, the experimental animal showed scrambling and nervous behaviors. Immediately from the beginning of the first module of the swing, an acute and transitory tachycardia associated with the irregular and intense movements were observed. In contrast to heart rate, respiration rate did not show any association with the swing movements but with the lapse of time of swing treatment. At 30 min from the beginning, plasma concentrations of cortisol and glucose had elevated sharply to 4 and 3 times higher than basic values, respectively
