Effects of increasing energy intake and foraging behaviours on the development of stereotypies in pregnant sows

Twenty-four second parity sows in the eighth week of gestation were classified according to their activity level. Sows within each group were randomly assigned to either a “high-energy” (HE, 1.7 times more […]
