| In der ökologischen Tierhaltung ist der Weidegang unverzichtbar. Mit Weidegang ist jedoch ein erhöhtes Risiko für Endoparasiteninfektionen verbunden. Um die Gesundheit der Tiere zu erhalten bei möglichst geringem Arzneimittelverbrauch, sind angepasste Strategien erforderlich. Einige Verfahren werden hier vorgestellt. Vorausschauendes Weidemanagement und gezieltes, selektives Entwurmen kann den Einsatz von Entwurmungsmitteln deutlich reduzieren. Die Kontrolle der Endoparasiten in der ökologischen Weidewirtschaft ist anspruchsvoll und benötigt zusätzliche Arbeitsstunden und Weideflächen. |

| Gule blomster var ikke noget særsyn i vårsæden i det forgangne vækstår. Enkelte marker var så befængte med enten agerkål eller agersennep, at man nemt kunne forveksle afgrøden med raps. De korsblomstrede ukrudtsplanter var ikke kun dominerende i marker, hvor problemet er tilbagevendende, men også i marker, hvor der ikke før er observeret agerkål eller agersennep. Dette fik nogle økologer til at få den mistanke, at såsæden indeholdt frø af især agersennep. Andre havde en mistanke om, at den importerede husdyrgødning indeholdt frøene. Virkeligheden er nok, at betingelserne for de to arter har været ideelle i år, hvormed frø, der har ligget i jorden gennem adskillige år, kom til spiring netop i år. |

| Health and welfare is a major topic in the Netherlands in both organic and non-organic dairy farming. This report highlights issues arising from welfare assessments conducted on Dutch farms producing milk for Ben and Jerry’s (B&J) ice cream. The Netherlands is the base for the European market for B&J ice-cream. Four years ago 11 farms were asked to produce milk for B&J. High human and animal welfare was a pre-condition. In order to evaluate the animal welfare on those farms, cows were assessed at the end of the housing season and at the end of the grazing season. At a plenary meeting the farmers discussed the results and the possible improvements on their farms. Since the farmers had a desire to control things on their own farms, they wanted to... |

| 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. |

| Risikoen for vindspredning af GM pollen fra raps og rug til økologiske marker med samme af-grøde er undersøgt ved hjælp af en atmosfærisk computermodel. Modellen er en videreudvikling af den danske Operationelle Meteorologiske Luftkvalitetsmodel. Modellen kan anvendes til at påvise generelle forhold hvor der er særlig stor eller lille risiko for GM-spredning til økologiske marker (f.eks. markplacering og vindforhold). Således kan modellen bruges til at undersøge risi-koen for vindspredning til de enkelte marker i landskabet. Spredningsmodellen inddrager meteo-rologiske data, afgrødens blomstringsperiode samt fysiske parametre for pollenet til beregninger af spredningen fra andre marker i landskabet. Modelberegningerne af den rumlige fordeling af... |

| Faeces plays a prominant role in the transmission of three major diseases in housed cows, namely, lameness, mastitis and Johne’s disease (Amory et al., 2006; Hughes, 1999; Anon., 2002). Cows show no evidence of latrine behaviour and because their eliminative patterns appear to be random, it is assumed that they have little control over it and that they make no attempt to avoid bodily contamination with excreta (e.g., Hafez and Schein, 1962). The cleanliness of housed cattle is therefore considered to be solely a management issue. At pasture, cattle are known to strongly avoid grazing near dung patches where faeces and the surrounding contaminated grass act as reservoirs for parasites (Marten and Donker, 1964a;b). Michel (1955) found bovine grazing to... |

| De fire arter, som studene selekterede positivt, var alle naturarter, nemlig alm. kvik, manna-sødgræs, alm. hønsetarm og fløjlsgræs. Af de arter, som studene selekterede negativt, var der to kulturarter, rød svingel og engrapgræs, samt to naturarter, mosebunke og knæbøjet rævehale. Studenes selektion var ikke knyttet til kvalitet for foderværdi i form af fordøjeligt organisk stof, råprotein eller cellevægsindhold (NDF). |
