| Dairy farming is the largest agricultural contributor to greenhouse gas emissions in Europe. In this study, the carbon footprint of organic dairying was evaluated by means of a life cycle assessment, based on real farm data from six European countries: Austria, Belgium, Denmark, Finland, Italy and United Kingdom. A total of 34 farms were analysed. The assessment was carried out using an attributional approach with system boundaries from cradle to farm gate. In relation to dairy production, a functional unit of 1 kg of energy corrected milk was used. The results gave an average of 1.32 kg CO2 equivalents per kilogramme of energy-corrected milk with standard deviation of 0.22, which is consistent with recent studies. The main contributor to this is enteric... |

| The effects of strain, sex and age on live weight, slaughter weight and sensory characteristics of organically reared broilers in orchards are presented. A total of 450 broilers of three different strains (I 657, Light Sussex, New Hampshire) were reared in an organic research orchard. Half of each strain was slaughtered at 91 days and the other half at 120 days. All broilers were weighed and a clinical welfare assessment was made at slaughter. A trained sensory panel evaluated the breast meat in relation to flavour, smell and texture characteristics defined by the panel. At both 91 and 120 days of age the commercial breed I 657 was significantly heavier than the slower growing strains. Males were significantly heavier than the females across strains.... |

| Outdoor rearing of finishers can be considered a relevant option in organic pig production. The performance and carcass characteristics of 245 organically produced and free-range born crossbred pigs allocated to five treatments were compared. The five treatments were: transfer to a barn with free access to feed (1) at weaning and until slaughter, (2) at a live weight of 40 kg and until slaughter, (3) at live weight of 80 kg and until slaughter, or reared at pasture (4) with free or (5) limited access to concentrates until slaughter. Pigs fed ad libitum fed indoor compared to pigs fed ad libitum outdoor had a significant lower feed consumption (5 MJ ME /kg gain), lower lean percentage (2.3%), and a higher backfat depth (1.1 mm)(all P < 0.05). Compared... |

| The development in organic livestock production can be attributed to an increased consumer interest in organic products while, at the same time, increased farmers' interest in converting to organic production methods—often stimulated by governmental support or subsidies. It is important that organic production systems can fulfil the expectations of each of these stakeholders if organic livestock production is to increase further. This is of particular importance if organic pig and poultry production (other than egg) is to move from the present niche-production to a significant place in the food market, as in the case of beef and milk. It can be argued that the limited organic pork and poultry production is related to the fact that it is far more... |

| Organic rules for grazing and access to outdoor area in pig production may be met in different ways, which express compromises between considerations for animal welfare, feed self-reliance and negative environmental impact such as greeehouse gas emissions and nitrate pollution. This article compares environmental impact of the main organic pig systems in Denmark. Normally sows are kept in huts on grassland and finishing pigs are being raised in stables with access to an outdoor run. One alternative practised is rearing also the fattening pigs on grassland all year round. The third method investigated was a one-unit pen system mainly consisting of a deep litter area under a climate tent and with restricted access to a grazing area. Using life cycle... |

| An experiment with slaughter pigs from weaning to slaughter including five treatments and five replicates was carried out at the Danish organic experimental station, Rugballegård. Treatments included full or partial outdoor rearing of the pigs, and the replicates covered the seasonal effects. Pigs fed ad libitum indoors had a significantly lower feed consumption (5 MJ ME /kg gain), a lower lean percentage (2.3% points), and a higher backfat depth (1.1 mm, P < 0.05) than pigs fed ad libitum outdoors. Compared with outdoor pigs fed ad libitum, restricted feeding outdoors resulted in a significantly lower daily gain (107 g), a lower feed consumption (6.3 MJ ME/kg gain), higher lean percentage (2.1% points), and a reduced backfat (1.8 mm) (P <0.001).

| Two experiments were conducted to study the effects of different forage crops on productivity and some egg quality parameters of small flocks of organic laying hens fed whole wheat or concentrates. Each experiment was carried out in a split plot design with two different forage crops and two types of supplementary feed (typical concentrate for organic layers versus whole wheat) with three replications. In the first experiment the tested forage crops were of a well-established grass/clover and a mixture of forbs (Fagopyrum esculentum, Phacelia tanacetifolia and Linum usitatissimum). In the second experiment the tested forage crops were a well-established grass/clover and chicory (Cichorium intybus cv. Grassland Puna). The results on productivity and egg... |

| Den sortbrogede danske landrace er meget forskellig fra de moderne krydsninger. Økologisk svinekød og økologiske kyllinger er betydeligt dyrere end tilsvarende konventionelle produkter. Derfor har mange forbrugere en forventning om, at de økologiske produkter adskiller sig fra de konventionelle - og at kvaliteten retfærdiggør merprisen. Det er baggrunden for, at der i projektet: Kvalitet og integritet i økologiske æg-, kyllinge- og svinekødsprodukter undersøges strategier for mere forskelligartet svine- og kyllingeproduktion. |

| Formål med at etablere vedagtig bevoksning på græsarealer til frilandssvin: 1) Forbedre dyrevelfærden ved at give grisene adgang til et nærmiljø, der i højere grad afspejler grisens "naturlige" nærmiljø, og som giver grisene langt større mulighed for thermo-regulerende adfærd end på arealer udelukkende med græs. Græsfoderet vil kunne blive suppleret med frugt fra træerne og give beskæftigelse. Det vil derudover have en landskabsæstetisk betydning i forhold til at gøre hytterne mindre synlige i landskabet. Af hensyn til vinterperioden er det ønskeligt, at der også indgår stedsegrønne træer i beplantningerne. 2) Reducere kvælstofudvaskningen ved at etablere vedagtig bevoksning, der forventes at være mere bestandig end græs, der erfaringsmæssigt er... |

| There has been a tremendous growth in numbers of organic farms in EU over the latest years – from below 20,000 farms in year 1992 to more than 120,000 farms in 1999 (Padel, 2001). Worldwide-certified organic production takes place in 130 countries, half of which are developing countries (ITC, 1999). The market share in EU, however, on total is still quite low ranging from less than 0.5% in nine out of 18 countries some countries to 5-9% in other countries for some major product groups (Michelsen et al., 1999). Livestock production and especially ruminant livestock production forms an integral part of many organic farms due to its role in nutrient recycling on farms. Out of 16 European countries, livestock products were within the top five organic products... |

| Undersøgelser viser, at der er et stort potentiale for et udvidet salg af svinekød. Økologisk svineproduktion skal dog i fremtiden leve op til forøgede kvalitetskrav mht. miljøbelastning, husdyrvelfærd og sundhed. Rapporten er udarbejdet på baggrund af en vidensyntese om muligheder og begrænsninger i økologisk svineproduktion. I rapporten præsenteres tilgængelig viden om svineproduktionssystemer, sygdomsrisiko ved frilandsproduktion, stimulering af svins modstandsdytighed mod infektioner gennem fodringsstrategier, svins forsyning med essentielle næringsstoffer og produktkvaliteten. |

| The effects of age, sex and genotype on growth and sensory characteristics in organically produced broilers, when kept considerably longer before slaughtering, were examined. A total of 450 birds consisting of three genotypes, Light Sussex, New Hampshire, and the commercial strain I 657 were inserted at Fejoe Research Orchard. Half the birds were slaughtered at 91 days of age and half at 120 days of age. I 657 was significantly heavier compared to the slower growing breeds and Light Sussex was significantly heavier than New Hampshire. Males were significantly heavier than females across genotype, but weight ratios differed with genotype. No overall effect of genotype was found on the flavour or smell of the breast meat, but the commercial strain went... |

| Organic pig production has emerged as an alternative to the intensive conventional pig production in Europe with the animals confined indoors and often an imbalance between livestock and land for feed production and manure utilisation. The organic systems aim at improving animal welfare by supporting the pig’s natural behaviour (Hermansen et al., 2003), and improving soil fertility by better linking crop and livestock production from an agro-ecological point of view. The differences between organic and conventional pig production is more fundamental than for example differences between dairy production systems, which may be why the share of pig herds within the organic holdings is considerably lower than the percentage of pig herds in conventional... |

| While there is a markedly growth in organically farmed land and in the organic food sector as such in Europe and North America, the organic pig sector has not developed correspondingly in most countries. This weaker development seems most likely to be due to difficulties for pig producers to comply with the organic standards, which impose comparatively more pronounced changes in the way of production than e.g. in ruminant production systems. Pigs should have access to roughage and to grazing in the summer period although finishers can be kept in barns if access to an outdoor rum. A common way to comply with these regulations is to have sows on grassland all year round, but to rear the finishers in stables. Outdoor piglet production can be very efficient... |

| Integrated forage and livestock production can be considered at the farm level and at the herd or animal level. At the farm level it is relevant to consider the overall utilization of N in the system in relation to crops and livestock. It is demonstrated that in organic dairy production a high transformation efficiency of N from input to edible products can be achieved compared, with conventional production. In addition, combining dairy and pig production allows an even higher N utilization. At the herd level the quality of grass or clover-grass based forage is extremely important. This holds for the overall intake and milk production in dairy cows and for the intake of clover-grass by grazing sows. In addition the composition of the sward should be... |
