观察生活在多窝组中的家猪及其母猪和其他猪在一个大的，社会和生态丰富的户外围栏，以获得在玩耍过程中进行的行为模式的频率和序列的定量描述。采用焦点动物取样法收集14只雄性和21只雌性仔猪从出生到14周龄的嬉戏行为数据。“游戏标记”跳跃、奔跑、旋转、甩头、摇动物体和搬运物体被用来识别游戏行为序列。各种不同的行为模式进行的一阶过渡与播放标记是最高的前6周，此后随着年龄的增长而下降。在具有玩耍标记的过渡中发生的行为模式显著多于预期，包括站立、行走、小跑、疾驰、冻结、推挤和转圈。玩耍标记的总体频率受年龄的影响很大，在2至6周龄之间出现峰值频率。雄性和雌性仔猪以相似的速率进行玩耍标记。结果进行了讨论，参考福利的仔猪保持在住房系统，限制嬉戏行为。
Domestic piglets living in multi-litter groups with their dams and other pigs in a large, socially and ecologically rich outdoor enclosure were observed, to obtain a quantitative description of the frequencies and sequences of behaviour patterns performed during play. Focal animal sampling was used to collect data on the playful behaviour of 14 male and 21 female piglets from birth to 14 weeks of age. The "play markers" hop, scamper, pivot, toss head, shake object and carry object were used to identify playful behaviour sequences. The variety of different behaviour patterns performed in first order transitions with play markers was highest in the first 6 weeks and declined thereafter with increasing age. Behaviour patterns occurring in transitions with play markers significantly more often than expected included stand, walk, trot, gallop, freeze, shove and circle. The overall frequency of play markers was significantly affected by age, with a peak frequency occurring between 2 and 6 weeks of age. Male and female piglets performed play markers at similar rates. Results are discussed with reference to the welfare of piglets kept in housing systems which limit playful behaviour.
