The influence of visual and tactile stimuli on the elicitation of prey-catching behaviour of ferrets was to be studied. For this study 16 animals, males and females, some naive and others experienced in catching and killing mice and rats were used. The behaviour of the ferrets toward 16 dummies with different characteristics was analysed under standardized conditions. Prey catching reactions of ferrets can be elicited by moving dummies. Dummies up to a certain size reliably elicit hunting reactions if they are moving at a speed of 25 cm/sec to 45 cm/sec. Moving objects, more than double the size of a ferret, cause avoiding reactions. Objects with a fur-like surface release more biting than objects with a hard surface. When hunting, ferrets-innately-tend to aim at the most anterior part of the "prey" and to bite into it, independent of whether there is a head-like structure with a neck or not.
本研究旨在探讨视觉和触觉刺激对雪貂捕食行为诱发的影响。为此,使用了16只动物,包括雄性和雌性,其中一些是未接触过的,另一些则有捕捉和杀死小鼠及大鼠的经验。在标准化条件下,分析了雪貂对16个具有不同特征的假猎物的行为。移动的假猎物可以引发雪貂的捕食反应。如果假猎物以每秒25厘米至45厘米的速度移动,尺寸在一定范围内的假猎物能够可靠地引发捕猎反应。尺寸超过雪貂两倍以上的移动物体会引发躲避反应。表面类似皮毛的物体比表面坚硬的物体引发更多的撕咬行为。在捕猎时,雪貂天生倾向于瞄准“猎物”的最前端并咬入其中,无论是否存在带有颈部的类似头部的结构。
