Velfærdsvurderingsrapporter fra økologisk ægproduktion. Rapport fra afdelingen for Husdyrsundhed og Velfærd, Danmarks Jordbrugsforskning
Provedor de dados: 21
Autores: Hegelund, L.; Sørensen, J.T.; Horsted, K.; Hermansen, J.E.
En af grundideerne i den økologiske fødevareproduktion er princippet om god dyrevelfærd for husdyrene, og det er et område der er kommet stadig mere fokus på i de senere år. Dyrenes velfærd afhænger i høj grad af sammenspillet mellem dyr, system og den daglige pasning, og der forventes derfor en stor variation i dyrenes velfærd fra bedrift til bedrift.    Husdyrenes velfærd kan betragtes som et produktionsmål på linie med produktivitet, produktkvalitet og bedriftens miljøpåvirkning, og det er derfor nødvendigt for ægproducenten at have en metode til vurdering af hønernes velfærd på flokniveau. En velfærdsvurdering skal beskrive velfærden i flokken i hele produktionsperioden vha. en række forskellige registreringer.    De data, der indsamles til brug i en...

Outdoor production of slaughter pigs requires an optimized management to mitigate N pollution
Provedor de dados: 21
Autores: 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’...

An approach to include soil carbon changes in life cycle assessments
Provedor de dados: 21
Autores: Petersen, B.M.; Knudsen, Marie Trydeman; Hermansen, J.E.; Halberg, Niels.
Globally, soil carbon sequestration is expected to hold a major potential to mitigate agricultural greenhouse gas emissions. However, the majority of life cycle assessments (LCA) of agricultural products have not included possible changes in soil carbon sequestration. In the present study, a method to estimate carbon sequestration to be included in LCA is suggested and applied to two examples where the inclusion of carbon sequestration is especially relevant: 1) Bioenergy: removal of straw from a Danish soil for energy purposes and 2) Organic versus conventional farming: comparative study of soybean production in China. The suggested approach considers the time of the soil CO2 emissions for the LCA by including the Bern Carbon Cycle Model. Time...

Sow body condition at weaning and reproduction performance in organic piglet production
Provedor de dados: 21
Autores: Kongsted, A.G.; Hermansen, J.E.
The objective was to investigate the variation in backfat at weaning and its relations to reproduction results in organic sow herds in Denmark. The study included eight herds and 573 sows. The average backfat at weaning mean�13 mm; SD�4.2 mm) ranging from 10.5 to 17.3 mm among herds shows that it is possible to avoid poor body condition at weaning even with a lactation length of seven weeks or more. No main effect of backfat at weaning on reproduction performance was found, but the probability of a successful reproduction after weaning tended to decrease with decreasing backfat for first parity sows, whereas the opposite was the case for multiparous sows.

Impact of large-scale organic conversion on food production and food security in two Indian states, Tamil Nadu and Madhya Pradesh
Provedor de dados: 21
Autores: 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...

Effect of breed on performance and meat quality of first parity sows in a seasonal organic rearing system
Provedor de dados: 21
Autores: 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...

Slagtesvin på friland kræver optimeret driftsledelse for at mindske miljøbelastningen
Provedor de dados: 21
Autores: Eriksen, J.; Hermansen, J.E.
Ved produktion af svin på friland er det almindeligt at have søerne på græs, mens smågrisene ved fravænning sættes på stald med adgang til et betondækket udeareal. Det kan forekomme paradoksalt at en stor del af det økologiske svinekød stammer fra grise, som hovedparten af deres liv ikke har haft mulighed for naturlig adfærd i form af at rode, grave og græsse.    Når producenterne vælger ikke at have slagtesvin på friland hænger det blandt andet sammen med en række forventede negative effekter, såsom et stort arealkrav, stor arbejdsbelastning, stort foderforbrug og stort tab af næringsstof til omgivelserne. Der kan imidlertid stilles spørgsmål ved om den indendørs produktion af slagtesvin svarer til forbrugernes forventninger om dyrevelfærd i økologiske...

Strategies for a diversified organic pork production
Provedor de dados: 21
Autores: 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...

Free-range pigs foraging on Jerusalem artichokes
Provedor de dados: 21
Autores: Kongsted, A.G.; Horsted, K.; Hermansen, J.E.
Free-range pig production in Northern Europe is characterized by high inputs of concentrate on grassland. This increases risk of nutrient leaching, increases feed costs and puts a pressure on land resources. Pigs’ unique ability to find a part of their food directly in the field where they are kept should be taken into consideration. One below ground field forage characterized by very high yields and with great potential as fodder source is Jerusalem Artichokes (JA) tubers. The nutritional contribution from free-range foraging, growth, feed conversion and behaviour were investigated in 36 growing pigs foraging on JA and fed concentrates restrictedly (30 % of energy recommendations) or ad libitum. Behavioural observations were carried out weekly over the...

Elimination behaviour and soil mineral nitrogen load in an organic system with lactating sows – comparing pasture based systems with and without access to poplar (Populus sp.) trees
Provedor de dados: 21
Autores: Jakobsen, M.; Hermansen, J.E.; Andersen, Heidi Mai-Lis; Jørgensen, Uffe; Labouriau, R.; Rasmussen, Jim; Kongsted, A.G.
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...

The effect of breed and feed-type on the sensory profile of breast meat in male broilers reared in an organic free-range system
Provedor de dados: 21
Autores: 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...

Organic agriculture in relation to food security of developing countries
Provedor de dados: 21
Autores: Panneerselvam, P.; Halberg, N.; Hermansen, J.E.
A study was conducted to investigate the differences in farm production, input use and farm income between organic and conventional systems in three regions (Uttaranchal, Madhya Pradesh and Tamilnadu) of India. From each region, 40 organic and 40 conventional farmers were interviewed with semi structured questionnaire. The results showed that input costs were less in the organic system while either total farm yield or net margin was righter in the organic system in two of the three regions. In Tamilnadu specializing in rice production, rice yield was less under organic system while net margin did not differ signifcantly.     In addition, the IFPRI-IMPACT model was used to fnd out the impact of large scale conversion to organic farming on food security of...

Provedor de dados: 21
Autores: Horsted, K.; Allesen-Holm, B.H.; Hermansen, J.E.; Kongsted, A.G.
BACKGROUND: A sensory panel evaluated the sensory profile of breast meat from five broiler products: two conventional standard products (A and B) and three organic niche genotypes (I657, L40, K8) reared in an apple orchard.     RESULTS: Twenty-two sensory attributes were evaluated, and 13 differed significantly between the products. The aromas ‘chicken’, ‘bouillon’ and ‘fat’ scored highest and the ‘iron/liver’ aroma lowest for the niche products. The meat was more ‘tender’, ‘short’ and ‘crumbly’, and less ‘hard’ and ‘stringy’ in the standard products than in one or more of the niche products. Product ‘I657’ was less ‘juicy’ than the rest. ‘I657’ and ‘L40’ were more ‘cohesive’ and tasted more ‘sourish’ and less of ‘sweet/maize’ than the standard products....

A diversified organic pork production – presentation of a concept based on seasonal outdoor rearing of very small entire males
Provedor de dados: 21
Autores: Kongsted, A.G.; Hermansen, J.E.; Claudi-Magnussen, C.; Andersen, B.H.
The risk of boar taint in entire males is supposed to increase with increased age and weight. Thus, a method to reduce this risk may be to slaughter the pigs at a low age and weight. This strategy is investigated as part of a new concept for organic pig production. It is hypothesised that organic pork has to differ markedly from conventional in order to overcome the heavy price competition. A seasonal outdoor rearing system based on production of small entire males, large female pigs and sows slaughtered after their first litter is believed to be a feasible strategy for producing organic pork with high credibility and superior eating quality. The study included a traditional breed, the Danish Black-Spotted. 17 gilts farrowed in April. Within the first week...

Potential loss of nutrients from different rearing strategies for fattening pigs on pasture
Provedor de dados: 21
Autores: Eriksen, J.; Hermansen, J.E.; Strudsholm, K.; Kristensen, K.
Nutrient load and distribution on pasture were investigated with fattening pigs that: 1) spend a proportion of or their entire life on pasture, 2) were fed either restrictively or ad libitum, and 3) were weaned at different times of the year. The N and P retention in pigs decreased the longer they were kept on pasture. The contents of soil inorganic N and exchangeable K were significantly raised compared to the soil outside the enclosures but with no differences between treatments. Pig grazing did not affect extractable soil P. Regular moving of huts, feeding and water troughs was effective in ensuring that nutrients were more evenly distributed on the paddocks. Grass cover, as determined by spectral reflectance, was not related to the experimental...

Organic livestock systems: characteristics and challenges for improvement
Provedor de dados: 21
Autores: 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...

Effect of nose ringing and stocking rate of pregnant and lactating outdoor sows on exploratory behavior, grass cover and nutrient loss potential
Provedor de dados: 21
Autores: Eriksen, J.; Studnitz, M.; Strudsholm, K.; Kongsted, A.G.; Hermansen, J.E.
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...

Selv om der de sidste fire år har været en kraftig stigning i den økologiske svineproduktion i Danmark, udgør den økologiske slagtesvineproduktion mindre end 0,5% af den totale slagtesvineproduktion, og erfaringsgrundlaget for gennemførelsen af den økologiske svineproduktion er derfor spinkelt. I mange tilfælde er svineproduktionen indrettet således, at søerne holdes på friland, mens slagtesvinene året rundt opstaldes i stalde med tilhørende udearealer, og det er for sådanne systemer, at videngrundlaget er bedst.

Mere kvalitet og diversitet i økologisk svineproduktion
Provedor de dados: 21
Autores: Kongsted, A.G.; Claudi-Magnussen, C.; Hermansen, J.E.; Andersen, B.H.
Forbruget af økologisk svinekød i Danmark er steget markant de senere år, men på trods af dette er markedsandelen stadigvæk meget ringe. Kun 1% af det svinekød, der købes i Danmark, er økologisk produceret. Dette er væsentligt lavere end f.eks. økologisk mælk og økologiske æg, som har markedsandele på hhv. 35% og 27% (Gfk, 2009). En af forklaringerne kan være en betydelig merpris for økologisk svinekød sammenholdt med, at økologisk svinekød ikke i sig selv adskiller sig fra konventionelt svinekød. Forbrugeren, der står ved køledisken og skal vælge, kan ikke se forskel, og senere kan hun heller ikke smage den store forskel på det konventionelle og økologiske.  Det er vigtigt, at økologisk svinekød adskiller sig markant fra konventionelt både med hensyn til...

In this study the aim was to evaluate differences in the sensory profiles of breast meat from five broiler products: two conventional standard products (A and B) and three organic niche genotypes (I657, L40 and K8) reared in an apple orchard.    RESULTS: Thirteen out of 22 sensory attributes differed significantly between the products. The aroma attributes ‘chicken’, ‘bouillon’ and ‘fat’ scored highest and the ‘iron/liver’ aroma lowest for the niche products. The meat was more ‘tender’, ‘short’ and ‘crumbly’ and less ‘hard’ and ‘stringy’ in the standard products than in one or more of the niche...

Induction of lactational estrus in organic piglet production
Provedor de dados: 21
Autores: 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...

Det generelle indtryk af flokkens sundhedstilstand er god: holdet har en lav dødelighed, en høj læggeprocent, meget få gulvæg, en god vægtudvikling, bortset fra et enkelt fald, ingen tegn på fjerpilning eller problemer med fodhelse.     Strøelsens beskaffenhed har en indflydelse på udviklingen af fodbylder, sygdomsudviklingen, mulighederne for god fjerpleje, aktivering mv. Hos driftsgren 182-1 har strøelsen været af en meget høj kvalitet hele produktionsperioden igennem, dvs. med et meget lavt gødningsindhold i øverste lag, store mængder sand, ingen skorpedannelse eller fugt.

Organic and Low-Input Dairy Farming: Avenues to Enhance Sustainability and Competitiveness in the EU
Provedor de dados: 21
Autores: 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....

Carbon footprints of crops from organic and conventional arable crop rotations – using a life cycle assessment approach
Provedor de dados: 21
Autores: Knudsen, Marie Trydeman; Meyer-Aurich, Andreas; Olesen, Jørgen E.; Chirinda, N.; Hermansen, J.E.
Many current organic arable agriculture systems are challenged by a dependency on imported livestock manure from conventional agriculture. At the same time organic agriculture aims at being climate friendly. A life cycle assessment is used in this paper to compare the carbon footprints of different organic arable crop rotations with different sources of N supply. Data from long-term field experiments at three different locations in Denmark were used to analyse three different organic cropping systems (‘Slurry’, ‘Biogas’ and ‘Mulching’), one conventional cropping system (‘Conventional’) and a “No input” system as reference systems. The ‘Slurry’ and ‘Conventional’ rotations received slurry and mineral fertilizer, respectively, whereas the ‘No input’ was...

Influence of genotype and feeding strategy on pig performance, plasma concentrations of micro nutrients, immune responses and fecal microbiota composition of growing-finishing pigs in a forage-based system
Provedor de dados: 21
Autores: Kongsted, A.G.; Nørgaard, J.V.; Jensen, S.K.; Lauridsen, C.; Juul-madsen, H.R.; Norup, L.R.; Engberg, R.G.; Horsted, K.; Hermansen, J.E.
Among consumers in Europe and other parts of the world there is an increasing interest in high-value pork positioned with regard to animal welfare (Krystallis et al., 2012). Free-range pork production is considered more animal friendly because the system enables the animals to express their natural behaviour to a large degree. However, outdoor production of growing-finishing pigs on pastures as described by Halberg et al. (2010) has a major drawback in terms of high risk of nitrate leaching (Eriksen et al., 2006ab; Salomon et al., 2007). This is to a large extent related to high stocking densities combined with large input of nutrients from the supplementary feed (Eriksen et al., 2006ab). The use of supplementary feed is often higher in free-range compared...

Økologisk ægproduktion: Produktion, sundhed, ernæring og næringsstofhusholdning
Provedor de dados: 21
Autores: Hegelund, L.; Hermansen, J.E.; Sørensen, J.T.; Horsted, K.
Økologisk ægproduktion har bidt sig fast som en af Danmarks største økologiske fødevaresucceser målt som andel produceret og solgt økologisk. Økologisk ægproduktion er efter økologisk mælkeproduktion den vigtigste animalske økologiske produktion i Danmark. Det er imidlertid en produktionsform, der er følsom overfor kritik. I forbrugernes øjne er økologiske æg et alternativ til æg fra burægproduktion, som primært er kritiseret for manglende dyrevelfærd. Det er derfor vigtigt, at den økologiske ægproduktion kan dokumentere en tilfredsstillende dyrevelfærd. Dette aktualiseres af, at traditionel burægsproduktion er under udfasning i EU og at økologisk ægproduktion i fremtiden skal konkurrere mod nye alternative indhusningsformer med fokus på dyrevelfærd.

Global Governance for Environmentally Sustainable Food Systems: Certified Organics in a North – South and South-South Perspective
Provedor de dados: 21
Autores: Egelyng, H.; El-Araby, A.; Kledal, P.; Hermansen, J.E.
Challenged to consume with less environmental impact, consumers buy certified organic products to “proxy”  environmental governance. The paper explores how far certified organic agriculture is institutionally embedded in  Brazil, China, and Egypt. The three case studies illustrate how regulation, including standard-setting and certification  processes differ between south and north, in terms of the evolution and nature of certification, as well as stakeholders and agency involved in shaping the regulation. A comparative analysis is presented on south-south differences in this regard along with some possible explanations of these. The paper finally discusses the perspectives in the global success of organic certification and whether it has potential to...

Different standing crops for organic layers
Provedor de dados: 21
Autores: Horsted, K.; Hermansen, J.E.
In typical organic egg production systems nearly all the feed is imported and fed inside the henhouse. Moreover, most of the hens stay inside the house or predominantly use the area just in front of the hen house. In consequence many systems are exposed to an unacceptable accumulation of nutrients in the most utilized areas in the hen yard. It is the hypothesis that this drawback can be affected if the feeds for a higher degree are based on foraging within the hen yard.    The purpose of this study was to estimate the effect of including standing crops in the hen yard on feed intake, production parameters, recirculation of nutrients in the system and the welfare of the poultry.   Two experiments with different standing crops for laying hens were conducted...

The mating behavior and reproduction performance in a  multi-sire mating system for pigs
Provedor de dados: 21
Autores: Kongsted, A.G.; Hermansen, J.E.
An important aim of organic animal production is to allow natural animal behaviour. Regarding reproduction techniques,  artificial insemination is permitted but natural mating is preferred. The outdoor multi-sire system, where the sows are placed in large paddocks with a group of boars, is one example of a service system, which complies well with the organic ideals of facilitating natural animal behavior. However, very little knowledge is available about such system. Seven groups of in total of 47 sows and 31 boars were observed to study the mating behavior in an outdoor multi-sire mating system and the subsequent reproduction results. The time of start of courtship, behavior and the cause of disruption if the courtship was terminated, were recorded each...

Effect of poplar trees on nitrogen and water balance in outdoor pig production – A case study in Denmark
Provedor de dados: 21
Autores: 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 foraging on Jerusalem artichokes (Helianthus tuberosus L.) – Effect of feeding strategy on growth, feed conversion and animal behaviour
Provedor de dados: 21
Autores: Kongsted, A.G.; Horsted, K.; Hermansen, J.E.
The nutritional contributions from free-range foraging, growth, feed conversion and behaviour were investigated in 36 growing pigs foraging on Jerusalem artichokes (JA) and fed concentrates restrictedly (30% of energy recommendations) or ad libitum. Compared to the ad libitum fed pigs, the pigs fed restrictedly had a significant lower daily gain (560 vs. 1224 g pig_1), improved feed conversion ratio (17.6 vs. 42.8 MJ ME concentrate kg_1 live weight gain) and spent more time foraging JA tubers (7.9 vs. 1.1%). It is estimated that pigs fed restrictedly found approximately 60% of their energy requirement from foraging in the range.

Produktions- og miljømæssig samt økonomisk vurdering af økologiske svineproduktionssystemer baseret på slagtesvins fouragering
Provedor de dados: 21
Autores: Hermansen, J.E.; Jakobsen, M.
I økologisk svineproduktion som den foregår i Danmark i dag, har søer på friland i vid udstrækning mulighed for at udføre naturlig adfærd. Både søer og slagtesvin får tildelt grovfoder, har relativt meget plads at bevæge sige på og har adgang til friland og udendørs arealer. Disse fordele menes at være basis for det lave antibiotikaforbrug der ses i den økologiske svineproduktion (Bonde &amp; Sørensen, 2004; Edwards, 2005).   Der er imidlertid også en række ulemper af miljø- og velfærdsmæssig karakter knyttet til især den økologiske slagtesvineproduktion. Stort set alle slagtesvin kommer på stald i forbindelse med fravænning, hvor de har adgang til udendørsarealer med beton underlag (Hermansen et al., 2005). Dermed har grisene ikke samme mulighed for at...

Greenhouse gas (GHG) emissions from agriculture are a significant contributor to total Danish emissions. Consequently, much effort is currently given to the exploration of potential strategies to reduce agricultural   emissions. This paper presents results from a study estimating agricultural GHG emissions in the form of methane, nitrous oxide and carbon dioxide (including carbon sources and sinks, and the impact of energy consumption/bioenergy production) from Danish agriculture in the years 1990-2010. An analysis of possible measures to reduce the GHG emissions indicated that a 50-70% reduction of agricultural emissions by 2050 relative to 1990 is achievable, including mitigation measures in relation to the handling of manure and fertilisers,...

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.

In India, the number of farmers converting to organic farming has increased in the recent past despite the lack of government support in providing knowledge and extension to the farmers. The aim of this article is to investigate the perceived relevance, benefits and barriers to a conversion to organic agriculture in three different Indian contexts - in Tamil Nadu, Madhya Pradesh and Uttarakhand states. In each state, 40 farmers from both organic and conventional systems were interviewed. The findings indicated that conventional producers identified production and marketing barriers as the main constraints to adopting organic farming, while the age and education of the farmer were not deemed a problem. Lack of knowledge and lack of institutional support...

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...
