Organic and Low-Input Dairy Farming: Avenues to Enhance Sustainability and Competitiveness in the EU Organic Eprints
Scollan, Nigel; Padel, Susanne; Halberg, Niels; Hermansen, J.E.; Nicholas, Pip; Rinne, Marketta; Zanoli, Raffaele; Zollitsch, Werner; Lauwers, Ludwig.
Whether farming strategies built on continuing input intensification or relying on integrated natural resource management are more sustainable and competitive is at the core of the agricultural development debate. The five-year (2011–16) Sustainable Organic and Low Input Dairying (SOLID) project, funded by the European Commission, involved 25 partners across 10 European countries and was designed to support innovation in European organic and low-input dairy farming. Results show that such systems are very diverse, and need tailor-made farm-specific strategies and related policy measures. This article shows that low-input dairying has country-specific farm characteristics, and is potentially competitive when compared to more intensive dairying systems....

Contribution of organic farming to public goods in Denmark Organic Eprints
Jespersen, Lizzie Melby; Baggesen, Dorte Lau; Fog, Erik; Halsnæs, Kirsten; Hermansen, J.E.; Andreasen, Lise; Strandberg, Beate; Halberg, Niels.
The potential contribution of organic farming to the public goods, ‘Nature and Biodiversity’, ‘Environment’, ‘Energy and Climate’, ‘Human Health and Welfare’ and ‘Animal Health and Welfare’ in Denmark is guided and partly secured by the principles and specific requirements of the EU Organic Regulation. However, other factors, such as the production type, farm size, geographical location and—not the least—the management of the farm, also influence the contribution. Using the ban on synthetic pesticides and restricted use of antibiotics, including the requirements to compensate for and prevent such uses in organic farming, as examples, the positive and negative contributions of organic farming in relation to selected public goods were analysed. The...

Impact of large-scale organic conversion on food production and food security in two Indian states, Tamil Nadu and Madhya Pradesh Organic Eprints
Panneerselvam, P.; Hermansen, J.E.; Halberg, N.; Arthanari, P.M..
The millions of food insecure people in India are not solely due to inadequate food production, but also because some people are simply too poor to buy food. This study assessed how a large-scale conversion from conventional to organic production would impact on the economics of marginal and small farmers in Tamil Nadu and Madhya Pradesh, and on the total food production in these states. This study also considered a situation where fertilizer subsidies would be discontinued, with farmers having to carry the full cost of fertilizer. Results show that conversion to organic improved the economic situation of farmers although food production was reduced by 3–5% in the organic situation. Thus, the estimated economic values were higher in the organic system...

Induction of lactational estrus in organic piglet production Organic Eprints
Kongsted, A.G.; Hermansen, J.E..
The longer lactation period required in organic piglet producing herds reduces the potential number of produced litters per sow per year compared with that of conventional production. Induction and use of lactational estrus may be a way to increase the productivity in organic production. However, if lactational estrus is to be beneficial under practical husbandry conditions, it is crucial that the majority of sows are successfully mated within a few days to make batch farrowing procedures possible. The objective of this study was to investigate the occurrence and timing of lactational estrus in an organic outdoor system based on ad libitum feeding, individual housing until Day 35 in lactation, followed by grouping and introduction of a boar and weaning of...

Organic livestock systems: characteristics and challenges for improvement Organic Eprints
Hermansen, J.E.; Kristensen, T.; Ronchi, B..
There is generally a growing interest for organically produced food in Europe and North America, although in some countries the interest is stagnating. Organic animal productions in some countries make up to 10% of total production. The development of organic farming is driven by a mutual interest among: farmers who are sceptical towards the methods of conventional farming or aim for possible premium prices; consumers perceiving the products to be safer; and authorities seeing organic farming as a tool to reduce environmental load of the livestock farming systems. Existing evidence shows that levels of production experienced in organic production are often moderately reduced compared to conventional production or in some cases considerable lower (piglets...

FREE-RANGE GROWING PIGS - EFFECT OF FEEDING STRATEGY AND GENOTYPE ON ANIMAL BEHAVIOUR, PERFORMANCE AND MEAT QUALITY Organic Eprints
Kongsted, A.G.; Therkildsen, M.; Hermansen, J.E..
Scientific Workshop on Organic Pig Production, Hovborg Kro, Holmeåvej 2, 6682 Hovborg, DK June 12th and 13th 2013 Programme: June 12th 2013: 9-9.30: Coffee, bread, and welcome (Marianne Bonde, UHF) 9.30-10: Sandra Edwards (UK): Future challenges in organic pig production 10-11.30: Theme 1: Production of entire male pigs / Chaired by Jan Tind Sørensen The aim of organic pig production is to ensure high animal welfare and natural products. Banning castration is thus a logical step forward, but the risk of boar taint in the meat is a major barrier for marketing meat from entire male pigs. Is it possible to use genetic tools and breeding strategies to prevent boar taint? What is the effect of feeding, management, housing and hygiene? Is...

Strategies for a diversified organic pork production Organic Eprints
Kongsted, A.G.; Claudi-Magnussen, C.; Hermansen, J.E.; Andersen, B.H..
Possible reasons for the low market share of organic pork may be heavy price competition with conventional produced pork products combined with no or small distinctive characteristics in appearance and quality, both regarding eating quality (flavour, tenderness) and ethical quality (production methods). The overall aim of this study is to identify strategies for a diversified organic pork production with high credibility and superior eating quality based on pigs foraging in the cropping system, use of a traditional breed and no castration. Preliminary results indicate that the use of a traditional breed, the Danish Black-Spotted pig, might be a way to produce pork, which in appearance differ from conventional pork and at the same time improve the...

Effect of breed on performance and meat quality of first parity sows in a seasonal organic rearing system Organic Eprints
Kongsted, A.G.; Claudi-Magnussen, C.; Horsted, K.; Hermansen, J.E.; Andersen, B.H..
The objective was to compare the performance and meat quality of two different pig breeds: The modern crossbred Landrace x Yorkshire (LY) and the traditional Danish Black-Spotted (BS) breed. The LY gilts and four of the BS gilts were inseminated with semen from Duroc (D) boars, the remaining BS gilts were served by BS boars. The experiment was performed on 26 gilts over two years. RESULTS: The Black Spotted breed in general had smaller litter sizes and weaned on average in terms of kg piglet 35% less than the modern breed combination. Crossbred piglets of BS×D had growth rates from birth to weaning comparable with piglets of LY×D. Black Spotted first parity sows were significantly fatter and less meaty, and the meat was significantly redder and darker...

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...

Concepts for a multi-criteria sustainability assessment of a new more biobased economy in rural production landscapes Organic Eprints
Dalgaard, Tommy; Jørgensen, Uffe; Kristensen, I.T.; Gylling, M.; Dejgaard, J.; Dubgaard, Alex; Kjeldsen, Chris; Hermansen, J.E.; Turner, K.G.; Christen, Ben; Andersen, P.S..
This study presents a new approach to model the biophysical potentials for increased biomass harvest in Denmark, and a multi-criteria sustainability assessment of the socio-economic and environmental effects of different scenarios for such increased production and new biobased economy in rural landscapes. Thereby the results serve as input to the ongoing productivism – post-productivism debate related to rural spaces in Europe. Empirical results from a case study of large scale conversion to biorefenery technologies, aiming to increase the total Danish harvest of biomass by 10 million tonnes via the conversion to new types of crop production and land management, is used as an example, and will be related to the common conceptual model presented by the...

Outdoor production of slaughter pigs requires an optimized management to mitigate N pollution Organic Eprints
Eriksen, J.; Hermansen, J.E..
In Danish outdoor pig production the sows are usually kept on grassland, while their progeny are transferred at weaning to indoor housing with access to an outdoor concrete pen. It may seem paradoxical that a large part of meat consumed from outdoor systems comes from pigs that during the majority of their life have been prevented from natural behaviour such as rooting, digging and grazing. The explanation is the drawbacks of rearing growers outdoors including huge space demand, high work expenditure, high feed consumption and high environmental costs due to nutrient losses to aquifers and the atmosphere caused by high nutrient load and difficulty maintaining grass cover. However, it may be questioned if pigs reared indoors comply with consumers’...

The effect of breed and feed-type on the sensory profile of breast meat in male broilers reared in an organic free-range system Organic Eprints
Horsted, K.; Allesen-Holm, B.H.; Hermansen, J.E..
1. Studies on the sensory profiling of male broiler breast meat were carried out to evaluate the effect of two very different broiler breeds (JA757 and New Hampshire), two different feed types (broiler and grower feed) and age at slaughter (82 and 110 d). 2. The sensory profiling consisted of a pilot study, 4 training sessions, and finally the assessment. During the training session a panel of 9 assessors defined 17 attributes, which were used to describe the smell, texture and flavour of the breast fillets. Each attribute was evaluated on a 15-cm unstructured line scale. 3. The breast meat became significantly less hard, and more juicy and tender in the New Hampshire at 110 d of age, whereas the opposite was found in JA757, which also acquired a more...
