Abstract

Effects of feed intake (high: 44 or low: 33 MJ NE per day) and major dietary energy source (fat: 131 g/kg fat, 183 g/kg starch plus sugar; starch: 31 g/kg fat, 351 g/kg starch plus sugar) of lactating primiparous sows on postural behaviour (lying, sitting, standing) and nursing frequency were studied. At day 10 and 17 of lactation, behaviour of 48 sows (12 per treatment) was recorded during 24 h. Time spent on lying tended to be higher in sows fed the High feed intake (86.7 versus 81.7%; P=0.06), whereas the time spent on (7.3 versus 11.3%, P=0.02) and frequency (20.8 versus 16.2/24 h, P=0.03) of standing were higher in sows fed the low feed intake. Feed composition did not affect the behaviour of the sows. Time spent on lying decreased from day 10 to day 17 (87.1 versus 81.3%, P
