观察了3窝仔猪从出生到4小时龄的哺乳和打斗行为。虽然每头仔猪在此早期平均从7个乳头哺乳，但每头仔猪平均55%的哺乳时间是在单个乳头上度过的。通过对22窝1 ~ 21日龄幼仔吸吮行为的观察，进一步研究了乳头顺序的发育。稳定的乳头顺序的发展是渐进的，到哺乳期第2周结束时，大多数窝仔的乳头顺序已达到最稳定。然而，在大窝和低增长率的窝乳头订单是不稳定的。
The suckling and fighting behaviour of 3 litters of piglets was observed from birth to 4 h of age. Although each piglet suckled from an average of 7 teats during this early period, each piglet spent an average of 55% of its suckling time at a single teat. The development of the teat order was studied further by observing the sucking behaviour of 22 litters from 1 to 21 days of age. The development of a stable teat order was progressive and by the end of the 2nd wk of lactation the teat orders of the majority of the litters had reached their most stable. However, in large litters and litters with low growth rates teat orders were unstable.
