| The aim of this project was to compare the hygienic quality of the bedding, as well as the parasitic load, cleanliness and lying behaviour in heifers kept on either straw or wood chip deep bedding. Fourteen heifers kept in two pens were housed on straw or wood chip bedding for 43 days, after which the bedding material was switched for 43 additional days. Significantly more mould was found in wood chip than in straw and there was a tendency towards less yeast in wood chip. The heifers had a low faecal parasitic load. The results indicate that the wood chip treatment resulted in somewhat cleaner animals. The heifers had a significantly longer total lying time when kept on straw. In conclusion, wood chip deep bedding could be an option as bedding material,... |

| Forbedres grovfoderkvaliteten, via øget andel kløvergræs, stiger såvel foderoptagelsen som mælkeydelsen per ko per år og der opnås en meget positiv effekt på bedriften økonomien. Modelberegninger viser imidlertid også at kvælstofoverskud per ha i stiger dette system, med deraf øget risiko for kvælstofudvaskning. Som en konsekvens heraf er der behov for at se kritisk på den traditionelle ompløjning af græsmarkerne efter 2 til 3 år, frem for mere længerevarende marker. |

| Fazit: Die gegenüber früheren Untersuchungen gestiegenen Bestandsgrößen weisen darauf hin, daß sich im ökologischen Landbau ein ähnlicher Strukturwandel wie in der konventionellen Landwirtschaft vollzieht (Wachstum und Spezialisierung). Die Auswertung zeigt ferner, daß die Betriebe zunehmend bemüht sind, bereits jetzt den zukünftigen Haltungsvorschriften der EU-Verordnung zu entsprechen. Fast alle Betriebe führen Weidegang durch und trotz der relativ geringen Bestandsgröße haben die meisten Betriebe bereits Laufställe; Auslaufmöglichkeiten fallen demgegenüber allerdings noch ab. |

| Este trabajo analizó el desempeño de la cadena exportadora de manzana para consumo en fresco, en Uruguay, mediante el método de la matriz de análisis de políticas (MAP). Se trabajó con la variedad Royal Gala, una de las más exportadas localmente por su temprana maduración y su buena aceptación en mercados de valor, como el europeo. Se cuantificaron los efectos de las políticas públicas (impuestos, subsidios, cargas sociales) y las eventuales fallas de mercado que afectan los distintos eslabones, estimándose las potenciales transferencias de recursos, desde o hacia la cadena. Primero se computaron los ingresos y costos en los distintos eslabones considerados: producción, transporte, procesamiento y empaque. Se calcularon los beneficios privados y sociales... |

| L’Agriculture Biodynamique (BD) a été l’objet de nombreux efforts de recherches durant les dernières décennies, bien qu’une partie de la communauté scientifique regarde les méthodes biodynamiques avec scepticisme et les considère comme dogmatiques. Néanmoins, comme cela est montré dans cet article de synthèse, une part non négligeable des résultats présentés dans des revues scientifiques à comité de lecture et issus d’expérimentations contrôlées de plein champ, ou d’étude de cas, montrent des effets des préparations biodynamiques sur le rendement, la qualité du sol et la biodiversité. De plus, les préparations biodynamiques ont un impact environnemental positif en termes d’utilisation et d’efficacité énergétique. Cependant, le mode d’action mécanique des... |

| Aufgrund ihrer weiten Verbreitung und der erheblichen Pathogenität einiger Spezies stellen gastrointestinale Nematoden bei Weidetieren ein Gesundheitsrisiko dar. Die Kontrolle dieser Parasiten basiert seit mehreren Jahrzehnten nahezu ausschliesslich auf dem Einsatz von Entwurmungsmitteln (Anthelminthika). Diese Tatsache hat speziell bei den Magen-Darm-Nematoden (MDN) der kleinen Wiederkäuer und bei den kleinen Strongyliden des Pferdes weltweit zu einer erheblichen Resistenzentwicklung geführt, von denen im Falle der ovinen MDN sämtliche kommerziell verfügbaren Anthelminthika-Klassen betroffen sind. Da sich praxisreife Alternativstrategien für die Parasitenbekämpfung bisher nicht ausreichend etablieren konnten, führt die verschärfte Resistenzlage zu einem... |

| Co-existence is defined as the farmers being able to choose between conventional, organic and genetically modified (GM) crop production, in compliance with the relevant legislation on labelling rules and purity standards. Genes of cultivated plants spread in time and space through pollen and seed dispersal, and in addition handling during transport and processing may also disperse seeds. Consequently, suitable measures during cultivation, harvest, transport, storage, and processing are necessary to ensure co-existence. |

| During the last decades Denmark has experienced a growing interest in low-input farming systems like organic farming. These systems rely on a high soil fertility to maintain nutrient availability and plant health. Soil aggregation contributes to this fertility, because it is crucial to soil porosity, aeration and infiltration of water. This paper reports a study of two pairs of differently managed, neighboring fields. The aim was to elucidate long-term effects of the different farming systems on physical and biological variables with influence on bonding and binding mechanisms of soil aggregation. Each pair consists of an organically grown dairy farm soil, based on a forage crop rotation system, including grass (Org-FCS(G)) and a conventionally managed... |

| Organic dairy farming (ODF) is different from conventional dairy farming in management practices, but so far the same breeding goal (BG) is used, based on the same economic models (EM). However, ODF is based on the principles of organic agriculture defined by the IFOAM, which are not easily interpreted in economic terms and it may be uestionable to use a BG for ODF based on EM. In this study we set up three BGs for ODF in Denmark, one based on the principles of organic agriculture, one focusing on roughage consumption and feed efficiency, and one focusing on disease resistance. A questionnaire and desired gains index were used to set up the BGs. Correlations between these BGs and BGs based on EM were low. Which BG would be best suitable to use for ODF in... |
