| 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... |

| Organic agriculture is defined as a low-external-input-system but piglets’ necessity for high quality diets seems to contradict low-external-input feeding strategies. Hence, a total of 361 piglets was tested from day 14 – 63 post natum concerning performance, health status, losses and diet costs by means of four feeding strategies of 100% organic origin: (i) high-external-input diet, (ii) medium-external-input diet, (iii) lowexternal-input diet, each with grass-clover-silage as roughage source, and (iv) above mentioned low-external-input diet with straw replacing grass-clover-silage. The highexternal-input-diet achieved the significantly highest live weight gain; all other strategies were similar at a lower level. There were no differences in health... |

| Se ha tratado de encontrar el menor nivel de proteína cruda (PC) en dietas sorgo-pasta de soya adicionada con AA sintéticos que mantenga los resultados productivos de la dieta estándar; también se ha tratado de encontrar un aditivo capaz de mejorar la respuesta productiva de cerdos alimentados con dietas con baja proteína (DBP). Uno de estos aditivos podría ser el compuesto β-adrenérgico Ractopamina (RAC). Por ello, se realizó un experimento para evaluar el comportamiento productivo (ganancia diaria de peso, GDP; consumo de alimento, CAL; conversión alimenticia, CA; ganancia de carne magra, GCM), las características de la canal (área del músculo longissimus, AML; grasa dorsal, GD; porcentaje de carne magra, %CM) y la concentración de urea en plasma de 36... |

| In Denmark the organic sows farrow outdoor on pasture (picture 1) and the gestation sows are outdoor from 15 April to 1 November on pasture (picture 2). Some farmers also keep their weaned piglets on outdoor pasture (picture 3). In the project pEcosystem data from five herds have delivered their crop plan for 2016. This gives unique information on the land use in Danish organic pig production. |

| ‘Low input’ pig production systems are usually characterised by smaller herd size, more space per animal, lower capital investment, often outdoor management, provision of bedding, greater labour requirement and focus on animal welfare. Examples of ‘low input’ pig production systems are “Iberico” in Spain, “Neuland” pigs in Germany, “Scharrelvarkens” in The Netherlands, “Natura Farm” in Switzerland, “Label Rouge” in France and “Freedom Food” in United Kingdom. Organic pig production systems have similar characteristics to those described for ‘low input systems’ above. However, organic farming standards prescribe e.g. low stocking densities, access to outdoor runs, restrict the level of ‘bought in, non-organic’ feeds etc, which usually results in higher... |

| Against the background of a high prevalence of respiratory diseases among the workers with the housing of fattening pigs as well as conspicuous negative pulmonary results among the fattening pigs it will be necessary to determine within the framework of an interdisciplinary cooperating project the impact of and hazards for humans, animals and the environment wherever it occurred in fattening pig facilities. To achieve this research has been carried out in representative systems of housing fattening pigs especially taking into account organic systems with the use of straw in deep litter or minimal litter systems in comparison to conventional systems, where the straw was used as on occupation material. In correspondence with the current discussion in the... |

| Data from 82 purebred and crossbred Large White and Duroc barrows and gilts were used to describe the growth of carcass primal cuts, of tissues, and of several organs. Pigs were allowed ad libitum to a conventional diet, which contained com and soybean meal. Pigs were weighted weekly and were slaughtered when attained a liveweight over 90kg. An allometric pattern of growth was assumed. Within the observed range of liveweight, the carcass grew slower than the whole animal. An increase of carcass weight corresponds to a similar increase of lean, but also corresponds to a larger increase of fat tissues. A suggestion to slaughter pigs near to 90kg of liveweight is presented, in order to obtain leaner carcasses. |

| In der ökologischen Schweinemast wird immer wieder über die Eignung alter und moderner Schweinegenotypen sowie die Notwendigkeit eigener Zuchtprogramme diskutiert. Um beide Punkte beantworten zu können, sind Informationen über das Ausmaß möglicher Genotyp- Umwelt-Interaktionen bei relevanten Leistungsmerkmalen notwendig. Daher wurden 682 Schweine von 7 merkmalsdifferenzierten Genotypen auf zwei Leistungsprüfungsanstalten in jeweils ökologischer und konventioneller Haltung auf Merkmale der Mastleistung sowie Schlachtkörper- und Fleischqualität geprüft. Es zeigte sich, dass in der Mastleistung und der Schlachtkörperqualität sowohl die modernen den alten Genotypen als auch die konventionellen den ökologischen Prüfbedingungen überlegen waren.

| De fleste almindelige indvoldsorm i danske svin er helt afhængige af værtsdyrenes nærmiljø, fordi en del af deres livscyklus skal gennemføres uden for værtsdyret. Ormene udskiller æg, som deponeres med værtens gødning i dennes omgivelser, hvor æggene dernæst udvikler sig til mere eller mindre hårdføre infektive stadier, som enten kan gensmitte værten eller smitte nye værtsdyr. Danske svin er gennem mange år blevet koncentreret i stadig større og mere intensive besætninger. Sammen med en udbredt brug af medicinering har dette forårsaget en markant reduktion i forekomsten og intensiteten af parasitter. Den økologiske driftsform, hvor forebyggende medicinsk behandling ikke er tilladt, og hvor dyrene skal have rigelig strøelse og adgang til udendørs... |

| Alternative Fütterungskonzepte für hohe Leistungen im Biolandbau sind eine Herausforderung. Kurz- und mittelfristig fokussieren die Alternativen eine Äquivalenz zur konventionellen Fütterungspraxis. Hierfür benötigt die Schweizer Biolandwirtschaft mehr Ackerflächen, um hochwertige Eiweissfuttermittel ökologisch und nachhaltig produzieren zu können. Partiell können Nebenprodukte die Eigenversorgung erhöhen. Langfristig muss der Biolandbau aus dem konventionellen Sog der Leistungssteigerung in der Tierhaltung aussteigen. Das bedingt eigene Leistungs-, Qualitäts-, Markt- und andere Konsumentenansprüche, damit der Markt für tierische Produkte weiter an Bedeutung gewinnen kann. |

| The effects of feeding weanling piglets diets with three different levels of three organic protein crops on performance and health were studied. Diets with 10, 20 or 30% field beans (Vicia faba, variety Aurelia, tannin-free), 10, 20 or 30% white lupins (Lupinus albus, variety Dieta, alkaloid-low) and 20, 40 or 60% quinoa (Chenopodium quinoa, variety Atlas, saponin-free) were compared with a control diet containing 15% soybean expeller and 2.2% soybeans. Besides, the apparent ileal digestibility and the apparent total tract digestibility of nutrients of the control diet and the diets with 30% field beans, 30% lupins and 40% quinoa were assessed. At weaning, 1,055 weanling piglets were assigned to one of the 10 experimental treatments. The piglets were... |

| Derzeit wird in allen Bereichen der konventionellen Lebens- und Futtermittelherstellung Vitamin B2 als GVO-Derivat, welches im Fermenter mit Hilfe von gentechnisch verändertem Bacillus subtilis hergestellt wird, eingesetzt. Die Produktionen unter Biolabels bilden hier eine Ausnahme. Im Herbst 2007 wurde von Seiten der Hersteller von Biofuttermitteln eine europaweite Mangelsituation bei der Versorgung von synthetischem Vitamin B2 gemeldet. Es wurde der Wunsch geäussert, die Bio Suisse solle beim BLW eine Ausnahmebewilligung für Vitamin B2 aus Prozessen mit GVO beantragen. Im September 07 entschied der Bio Suisse Vorstand aber, dass keine GVO Derivate im Biolandbau eingesetzt werden dürfen. In der neuen EU Bioverordnung 834/07 fällt Vitamin B2 unter die... |

| Die betäubungslose Ferkelkastration ist ab 2010 in der Schweiz verboten. Auch in den EU - Ländern ist das Thema brandaktuell und vor allem die Bioverbände sind aufgefordert, eine Vorreiterrolle in der tiergerechten Ferkelerzeugung einzunehmen. Daher ist der Zeitpunkt für Wissenschaftler, Berater und Landwirte optimal, um sich im Rahmen eines Workshops über die vorhandenen Möglichkeiten auszutauschen. Für die Ferkelerzeuger gibt es verschiedene alternative Methoden. Neben den Betäubungsmethoden ist die Ebermast die Produktionsform der Wahl für biologisch wirtschaftende Betriebe. Bei der Umsetzung in der Praxis stellen sich den Betrieben bei allen Methoden Herausforderungen, die es zu meistern gilt. Rechtliche, arbeitswirtschaftliche, hygienische und... |

| Today in conventional food and feed production added vitamin B2 is produced almost exclusively from a GMO,1 namely the genetically modified Bacillus subtilis. Vitamin B2 applied in certified organic food and feed productions is an exception, as it is still synthesized conventionally. In fall 2007 and also recently, there has been a lack of non-GMO derived vitamin B2 on the European market, which has caused temporary supply problems for organic producers. This event triggered the political will to conduct new research in order to find alternative solutions for the substitution of synthetic vitamin B2 in organic agriculture. |
