Sows introduced to a new housing system containing farrowing pens with slatted floor showed increased occurrence of lesions of the vulvar region, caused by the piglets during the later stages of the lactation period. An investigation was undertaken in which the activity of the piglets, particularly rooting and investigatory behavior, was examined and compared to that of piglets kept on straw. Although the occurrence of vulvar lesions disappeared spontaneously before the conduction of the investigation, the results revealed that piglets on slatted floor spent significantly more time chewing on inappropriate objects such as other group members or the vulva of the sow, whereas the rooting and investigatory behavior of piglets raised on straw was almost exclusively directed towards the straw. The results confirm previous observations that piglets living in a relatively poor environment show a greater tendency to direct their activity towards inappropriate objects. If the housing system is otherwise healthy, the change in behavioral activity remains insignificant. If, however, other minor disturbances occur in the system, in the present case clinically insignificant lesions on the vulva of the sow caused by the new slatted floor, aggravation of the lesions can occur due to this change in piglet activity.
引入装有带缝隙地板产仔栏的新饲养系统的母猪,在哺乳期后期出现了由仔猪导致的外阴部区域损伤增多的情况。开展了一项调查,对仔猪的活动,尤其是拱掘和探究行为进行了检查,并与饲养在垫草上的仔猪进行了比较。尽管在外阴部损伤在调查开始前已自行消失,但结果显示,生活在带缝隙地板上的仔猪花费大量时间啃咬不适当的物体,如其他群体成员或母猪的外阴,而饲养在垫草上的仔猪的拱掘和探究行为几乎完全针对垫草。结果证实了先前的观察结果,即生活在相对较差环境中的仔猪更倾向于将其活动指向不适当的物体。如果饲养系统在其他方面是健康的,行为活动的变化仍然不显著。然而,如果系统中出现其他轻微干扰,在本案例中是由新的带缝隙地板导致的临床上不显著的母猪外阴损伤,由于仔猪活动的这种变化,损伤可能会加重。
