Effect of poplar trees on nitrogen and water balance in outdoor pig production – A case study in Denmark Organic Eprints
Manevski, Kirl; Jakobsen, Malene; Kongsted, A.G.; Geogiadis, Petros; Labouriau, R.; Hermansen, J.E.; Jørgensen, Uffe.
Nitrate leaching from outdoor pig production is a long-standing environmental problem for surface and groundwater pollution. In this study, the effects of inclusion of poplar trees in paddocks for lactating sows on nitrogen (N) balances were studied for an organic pig farm in Denmark. Vegetation conditions, soil water and nitrate dynamics were measured in poplar and grass zones of paddocks belonging to main treatments: access to trees (AT), no access to trees (NAT) and a control without trees (NT), during the hydrological year April 2015 to April 2016. Soil water drainage for each zone, simulated by two simulation models (CoupModel and Daisy), was used to estimate nitrate leaching from the zones in each paddock. N balances (input minus output) for the...

Free-range pigs integrated with agroforestry Organic Eprints
Jakobsen, Malene; Kongsted, Anne Grete.
Among consumers there is an increasing interest in pork from conventional and organic free-range production. In many ways free-range production support animal welfare in terms of animals being able to perform species-specific behaviour. However, there are also some serious challenges related to animal health and welfare. Sudden death of lactating sows related to the disease complex called ‘summer-sows’ is a huge challenge on some farms and is expected to be related to heat stress. Furthermore, sows are snout-ringed which prevents them from performing species-specific behaviour such as rooting. Rooting destroys the grass cover thereby increasing the risk of nutrient leaching. Integration of free-range pigs with agroforestry, e.g. production of tree biomass...

Improved sustainability in organic pig production Organic Eprints
Kongsted, Anne Grete; Hermansen, John E.; Jakobsen, Malene.
The local and global sale of organic pork produced in Denmark has increased markedly in recent years. Organic pig production is associated with several positive aspects from a societal point of view e.g. very low use of antibiotics and animals being able to express more of their natural behavior compared to conventional production. However, there are some challenges regarding sustainability that needs to be addressed. In Denmark, organic pig production is based on outdoor sow production all year round while the majority of growing pigs are kept in stables with access to a concrete covered outdoor run. The outdoor production of sows imposes a significant risk of nutrient leaching, especially in paddocks with lactating sows. The outdoor run for growing pigs...

Including trees in pasture-based pig systems to improve animal welfare and eco-efficiency Organic Eprints
Jakobsen, Malene; Kongsted, A.G..
The overall idea is that trees in a pasture-based system will provide a more natural and stimuli-rich environment for the pig with possibilities to seek shadow in hot periods and shelter during Cold periods.

Integrating foraging and agroforestry into organic pig production - Environmental and animal benefits Organic Eprints
Jakobsen, Malene.
Outdoor organic pig production is associated with significant risk of nitrogen (N) leaching with a subsequent increased risk of polluting nearby surface and ground water sources. Contributing factors are high input of supplementary feed and a relatively high animal stocking density combined with pigs’ heterogeneous deposition of urine and faeces within the paddock. In addition, pigs’ rooting behaviour destroys the grass cover, which adds to the risk of nitrate leaching. In particular, risk of leaching severely increases during winter with periods of high rainfall and impaired grass growth. Based on concerns for the environment, snout ringing of sows is common practice. However, as pigs have a high motivation for rooting, this is a source of conflict...

Organic growing pigs in pasture systems – effect of feeding strategy and cropping system on foraging activity, nutrient intake from the range area and pig performance. Økologiske slagtesvin på friland – effekt af foderstrategi og afgrødesystem på fourageringsaktivitet, næringsstofindtag fra udearealet samt tilvækst og foderudnyttelse Organic Eprints
Jakobsen, Malene.
Production of organic growing pigs is characterized by indoor housing with access to outdoor concrete yards and feeding high amounts of supplementary feed based on grain and imported protein feed. However, this is not in accordence with the organic principles, which insist on optimization of nutrient recirculation, use of local renewable resources and animals being able to perform normal behaviour. The overall aim of the project was to contribute to development of an eco-efficent and trustworthy organic production system based on free-range growing pigs in pasture systems. The point of departure was to integrate the unique innate ability of pigs to forage above and below ground as a resource in the farming system. It was hypothesised that foraging in the...
