| The extraction of proteins from leaves, integrated in a green biorefinery, may represent an attractive solution to the increasing demand for protein-rich animal feeds while decreasing the dependency on soybean imports. Thereby such green biorefineries could contribute to the development of more self-sufficient and sustainable agricultural systems in Europe. The framework of this PhD study is a green biorefinery concept for the production of protein concentrate, biogas and fertilizer from organic and locally grown green crops like alfalfa, clover or grass. After the screw pressing of the fresh crops, lactic acid fermentation of the green juice with Lactobacillus salivarius BC 1001 was assessed as the key method for the recovery of proteins. A leaf protein... |

| Muuruvesi Organic Farm (owned by the Savo Vocational College) is situated in Eastern Fin-land (63° N 28° E). The fields of Muuruvesi farm have been under organic farming partly since 1988 and the whole farm since 1995. The arable area is 145 hectares and the soil type is mainly silt, containing 3-6 % organic matter. The crop rotation consists of silage, pasture, hay, oats, barley and peas. The farm has had organic milk production since 1998. There are 60 cows and average milk yield is 9,500 kg/year. A new cowshed was built in 2001 and now it is possible to make feeding experiments with cows in 2-3 groups. There is also 3,000 m² of greenhouse are in the organic production of tomatoes and cucumber and some pepper, honeydew melon and aubergine. |

| Parasites are ubiquitous in livestock in general and organic livestock in particular due to manage-ment factors promoting transmission (pastures/outdoor runs, plenty of bedding, restrictive use of parasiticides). The parasites cause poor animal welfare, production losses, disease, and non-uniform products. Pig helminths with hard-shelled eggs are difficult to control, as the eggs are highly resistant and may survive for years. The present project focuses on reducing the transmission of hard-shelled eggs to growing pigs by investigating 1) long-term survival of eggs on pastures (for optimising pasture rotation), 2) inactivation of eggs in bedding material (reducing transmission), and 3) a novel approach in bio-inactivation of eggs (chitin-degrading... |

| This is the final report from the Defra project OF0103 In the UK fewer than 50 dairy farms were registered as organic in June 1995. The slow increase of farmers willing to convert to organic milk production was seen as one impediment for development of the organic milk market. The overall objective of this joint 3-year project was to monitor the physical, environmental and financial implications of conversion to organic milk production on a research farm (Ty Gwyn) and ten commercial farms in southwest England and Wales, in order to provide policy makers and farmers with more information about the consequences of conversion. Although the size of the sample is comparably small it represents about 20% of all organic dairy farms in the UK and an even larger... |

| The essential nature of Phosphorus (P) in plant growth and the finite amount of P resources have result in the question: what kind of management in farming systems can lead to P sufficiency in organic farming? The release of acid and alkaline phosphatases of plant and microbes promote the plant availability of soil P. The presented results show a significant higher enzyme activity at permanent grassland (PG) than at arable land with annual crops at an organic farm in Northern Germany. Therefore livestock systems with PG for grazing ruminants seem to have high potential to improve on-farm P-cycles via feed and manure flows even to annual cropland. These systems can profit from the nutrient transfer from PG to arable land through the use of manures. Enhance... |

| O sistema rotacionado de pastagens é uma forma de manejo desenvolvida para garantir melhor eficiência na utilização da forragem, numa determinada área de pastagem. Neste estudo foram apresentados alguns resultados preliminares sobre um projeto piloto que visa avaliar a implantação de um sistema rotacionado, com pastagens nativas, numa fazenda particular na sub-região da Nhecolândia, Pantanal, MS. Este estudo piloto indicou que as novilhas mantidas em sistema rotacionado tiveram um melhor ganho de peso, quando comparadas com novilhas da mesma categoria mantidas em sistema contínuo, mas no ano anterior. Porém, como no Pantanal a dinâmica das pastagens é variável entre anos, estudos adicionais devem ser feitos comparando o sistema rotacionado com o contínuo,... |

| Die invasive Leguminose Lupinus polyphyllus (Vielblättrige Lupine) breitet sich in artenreichen Borstgrasrasen und Bergmähwiesen aus. Dort verdrängt sie gefährdete Rote-Liste Arten und verändert die Artenzusammensetzung. Wir führten ein Experiment durch um den Biomasseertrag und den Lupinenanteil an der Biomasse zu unterschiedlichen Nutzungszeitpunkten zu untersuchen. Zusätzlich wurde der Alkaloidgehalt der Lupinen ermittelt, da dieser einen Einsatz der Biomasse in der Tierernährung verhindern kann. Die Ergebnisse zeigten Bioamsseerträge vo 3,6 bis 3,9 t Trockenmasse pro Hektar und Lupinenanteile von ca. 30% im Mittel. Der Alkaloidgehalt in den Lupinen wies eine Spannweite zwischen 0,7 und 2,5% in der Trockenmasse auf und war signifikant abhängig vom... |

| Über die Steuergrößen Leguminosen- bzw. Begleitgrasart, Saatmischungsverhältnis, Etablierungsverfahren, Nutzungsart und -häufigkeit sowie Düngung lassen sich Ertrag, N2-Fixierungsleistung, Vorfruchtwert und Futterqualität von Kleegras in weiten Bereichen beeinflussen. Ziel der vorliegenden Studie war die Analyse des Einflusses der Begleitgrasart auf Ertrag und Qualität von binären Rot- bzw. Weißkleegrasgemengen unter Berücksichtigung des Reifetyps der jeweiligen Grasart (früh versus spät) unter norddeutschen Boden- und Klimaverhältnissen. Die Wahl der Begleitgrasart zeigte sich als wirksames Werkzeug in Bezug auf die Beeinflussbarkeit des Klee-Ertragsanteils und damit zentraler Futterqualitätseigenschaften von Kleegrasgemengen dar. Besteht die Gefahr zu... |

| Na presente revisão, buscou-se apresentar os principais impactos ambientais causados pela pecuária, sobretudo, em relação às emissões de gases efeito estufa (GEE). Além disso, buscou-se apresentar possíveis formas de mitigar essas externalidades. A criação de bovinos, no Brasil, acontece de forma extensiva, muitas vezes em áreas com pastagem degradada e, portanto, de baixa produtividade. Isso possibilita à atividade uma oportunidade de redução do impacto causado ao meio ambiente, uma vez que ações tomadas, no sentido de melhorar o rendimento animal, devem resultar em um menor consumo de recursos naturais (terra e água) e maior eficiência do sistema digestivo animal. Os principais problemas apontados pelos pesquisadores, no que tange à pecuária extensiva,... |

| Within a schedule of long-term organic forage crop rotations, two mixed stands of ryegrass-clover were evaluated as following crops after winter cereal-legume mixtures under different sowing and tillage methods in Asturias (N. Spain). Significant differences were found in productivity, sward components, chemical composition and in growth dynamics. The crop sequence perennial ryegrass-white clover established under a triticale-field bean canopy produced an additional 6 t DM/ha, compared with oat-vetch followed by Italian ryegrass-red clover under regular post-harvest sowing, thus being a promising method for improving organic forage productions with minimum tillage. Changes in productivity and feeding values observed for both these ryegrass-clover swards... |

| En grøn foderration med brug af urter i græsblandingerne gør det muligt i højere grad at blive selvforsynende med vitaminer og mineraler. Et forsøg med to økologiske fodringsstrategier har vist, at køer der ikke får tilskud af mineraler, men derimod får en foderblanding med et højt indhold af naturlige mineraler og vitaminer, har samme foderoptagelse, mælkeproduktion og reproduktion, som køer på en mere traditionel foderration. Blodprøver viste desuden, at køer, der udelukkende fik mineraler og vitaminer naturligt indeholdt i de forskellige fodermidler, havde samme A- og E-vitaminniveau i blodet, som køer der fik tilsat mineralblanding til foderet. |
