Extract

Fostering piglets at 7 days of aye influences the behaviour of ootn piglets and foster sow in many ways (ilorrell, 1932) and retards growth over the next week (Horrell & Bennett, 1981). The growth retardation is persistent and can occur to lesser degree in piglets fostered at 1 day and in resident piglets in the recipient litter (Horrell, Hodgson & LUNB, 1985). This investigation was designed to determine (a) tne behavioural effects in greater detail, and (b) the behavioural mechanisms retardation underlying the growth

Pairs of sows-(Landrace/Large White derived hyurid) which had farrowed 3-12 piglets within 14 h of each other had equal numbers of piglets exchangeu between them. They were then observed for 3 n immediately afterwards and for 1.5 h on each of 1, 3 and 7 d later.
