Description
Summary:Group housing systems for pregnant sows are set to become more popular, but there is evidence that this development could influence the welfare of sows in farrowing crates. A study was designed to assess the effect of gestation accommodation on behaviour, welfare and farrowing performance of sows in farrowing crates. Multiparous sows were housed loose [L] in groups of four with feeding stalls ( n=24) or individually in gestation stalls [S] ( n=24) from 1 month post-service. On day 110 of pregnancy, sows were moved to farrowing crates where they remained until 28 days post-partum. Behaviour was recorded on the first day in the crate and on day 10 of lactation. Posture changing frequency was recorded for 2 h prior to and for the duration of farrowing. Skin lesions were scored from 0 to 6 at 34 locations on the body the day before and the day after entry to the crate, post-farrowing, during weeks 2 and 3 of lactation and at weaning. On the first day in the crate S sows made significantly more attempts to lie down per lie down event than L sows ( P
