| Innovative strategies in free-range pig production is needed to improve the environmental performance of the system. Based on previous studies, inclusion of trees was hypothesized to improve the system’s nitrogen efficiency. We investigated sow elimination behaviour, faeces load and localisation as well as soil mineral nitrogen load in pasture based individual paddocks with and without access to two rows of poplar (Populus sp.) trees. Unlike expected sows showed no preference for eliminating in the zone with poplars but clearly avoided defecating near the hut, feed and water. Soil mineral nitrogen load showed a heterogeneous pattern as also found in previous studies. In comparison to grass, our results indicated that the poplars had an increased winter... |

| Nærværende rapport er udarbejdet i forsknings-, udviklings- og demonstrationsprojektet Pig production in eco-efficient organic systems (pEcosystem). Projektet er en del af OrganicRDD2 programmet som koordineres af ICROFS (Internationalt Center for Forskning i Økologisk Jordbrug og Fødevaresystemer). Projektet har fået tilskud fra Grønt Udviklings- og Demonstrationsprogram (GUDP) under Fødevareministeriet og er ledet af Institut for Agroøkologi, Aarhus Universitet, med deltagelse af Økologisk Landsforening, Udviklingscenter for Husdyr på Friland, SEGES samt to økologiske svineproducenter, Bertel Hestbjerg og Brian Holm.

| Finding ways to motivate pigs to excrete in dedicated areas is of major importance for the environment, human health and animal welfare. This review investigates pigs’ excretory behaviour and the relation to the rearing and housing environment in addition to identifying important knowledge gaps in this respect. Eliminating away from the nest/lying area appears to be innate but evolves over time. Postpartum, piglets urinate and defecate close to the nest, indicating that it is difficult to influence piglets’ choice of elimination area, as this is influenced by the sow’s choice of nest area. At increased age piglets begin to excrete further away from the nest, which is probably related to the fact that piglets start to spend more time away from it. There is... |
