对41头混合育种的处女、乳用型一岁小母牛的全部或部分进行了运动顺序观察。考察了不同运动序列中的位置与社会地位的关系。它被发现在自由运动从观察码回到围场，领导人不是最具优势的动物。自由放牧条件下，中、高优势值（D.V.）再次，实际的领导人是中等，而不是高D.V.强迫运动沿着围栏进行了比较，自由运动（放牧）相同的小母牛。强迫运动的领导人是小母牛低D.V.相对于自由运动，小母牛高D.V.回落，而小母牛低D.V.向前推进强迫运动。这些意见的关系，以前的意见在码进行了讨论。|| 摘要编辑：作者
Observations on movement orders were taken on all or a portion of 41 virgin, dairy type yearling heifers, of mixed breeding. The relation of position in various movement orders and social position were investigated. It was found in the free movement from the observation yards back to the paddock, the leaders were not the most dominant animals. Under free movement (grazing) conditions it was the heifers of medium and high Dominance value (D.V.) that preceded the animals of low D.V. Again the actual leaders were of medium rather than high D.V. Forced movement along a fence was compared with free movement (grazing) of the same heifers. The leaders of forced movement were heifers low in D.V. Relative to free movement, heifers high in D.V. dropped back while heifers low in D.V. moved forward in forced movement. The relation of these observations to previous observations in yards was discussed. || ABSTRACT AUTHORS: Authors
