I økologisk svineproduktion overføres fravænnede grise oftest til et staldsystem med dybstrøelse, tørfodring i automater og adgang til udeareal. Denne opdrætningsform muliggør en god styring af produktion og husdyrgødning, men kræver store investeringer. Et alternativ er at slagtesvinene går på græs i hele eller dele af deres produktionsperiode. Der er dog stor usikkerhed om, hvilke produktionsresultater, der kan nås. Tidligere resultater viste at foderforbruget blev stærkt forøget, hvilket samtidig betød høj næringsstofbelastning på markarealet. En kombination, hvor grisene starter på mark og går på stald i den sidste del af produktionsperioden kan måske have nogle særlige fordele i forhold til tilvækst, foderforbrug, miljøpåvirkning og håndtering af dyr.... |

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.... |

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... |

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... |

This study compared farm production, crop yield, input cost, and income in organic and conventional farming systems in three states of India: Uttarakhand, Madhya Pradesh, and Tamil Nadu. The results showed that organic farming reduced the input cost without affecting the net margin in all three states. Total food production was found to be comparable for the two systems in two of three states. While yield of rice and wheat generally was lower under the organic systems, yield from intercropping food crops was generally higher. The number of agro-ecological methods and percentage of farms practicing different agro-ecological methods were higher under organic systems than conventional systems. These results suggest that organic farming has the potential to... |

The development in organic livestock production can be attributed to an increased consumer inter-est in organic products while, at the same time, farmers are interested in converting to organic pro-duction methods – often stimulated by governmental support or subsidies. It is important that the organic production systems can fulfil the expectations of each of these stakeholders if the organic livestock production is to increase further. This is in particular important if the organic poultry pro-duction should move from the present niche-production to a real player in the food marked, like in the case of beef and milk. It can be argued that the limited organic poultry production is related to the fact that it is far more difficult for the farmers to... |

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... |

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... |

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... |

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. |

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... |

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... |

The aim of this chapter is to highlight some of the prospects and constraints for the development of the organic pig production. Livestock rearing should contribute to a more balanced overall production of the farm, food safety (in a wide sense) should be enhanced, and animal welfare should be compared better to conventional production methods. Futhermore, the environmental load should be low. The success of the expansion of organic systems will depend on to what degree these different expectations can be fulfilled without resulting in too high premium prices of the products. |

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). The... |

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. |
