| Outdoor sows are nose ringed to maintain grass cover. Intact pasture insures the sows possibility to graze and is also assumed to reduce the nutrient leaching. However, no evidence of reduced leaching from fields with ringed sows is available. Rooting behaviour constitutes an essential part of the sows’ natural behavioural repertoire. In organic husbandry it is an established aim to consider the animals’ natural behaviour, and by allowing nose ringing in organic pig production the natural behaviour of the animals has been prevented in order to consider the environment. The purpose of this experiment was to relate grazing and rooting activity of sows to grass cover and nutrient leaching. Three treatments were tested on 78 sows in total: 1: sows with nose... |

| Nose ringing of outdoor sows is practiced to reduce grass sward damage for environmental reasons but conflicts with natural behaviour considerations. We investigated effects of ringing pregnant and lactating outdoor sows on foraging and explorative behaviour, grass cover and nutrient deposition. The experiment included both ringed and unringed sows. For unringed sows the paddocks were either used continuously throughout the experiment or divided into two and sows were moved half way through the experimental period leaving the first used paddock for regrowth. Ringing did not prevent the sow’s rooting, but rooting was less pronounced, when sows were ringed. On average, ringing increased grass cover from 14 to 38% and from 64 to 81% in paddocks with pregnant... |
