| High mortalities among rainbow trout (Oncorhynchus mykiss) fry are often the result of infections caused by Flavobacterium psychrophilum, and in Denmark this pathogen can be found in nearly all freshwater fish farms. The infection can be treated with antibiotics, but lower sensitivity against the infection is an increasing problem for some of the used drugs, wherefore alternative treatment methods (e.g. bacteriophages) are investigated. Prophylactic measures (e.g. feed additives) are another approach, so infections with the bacterium can be avoided, before they become a problem. No matter if the focus is on prophylactic or alternative treatment, reliable infection models are needed to evaluate the treatments as well as to get more knowledge about... |

| As a part of the study 'Health and performance of dairy cows in organic farming from an interdisciplinary point of view 13 an (intervention-) study on metabolic disorders and mastitis with regard to forage production, feeding management and husbandry practices' different udder health and metabolic variables were determined in 106 dairy farms in Germany between January 2008 and April 2010. The objective of this study was to evaluate udder health risks and metabolic risks in dry period and early lactation. Udder health and metabolic situation were similar to conventional dairy farms. Identified risks for metabolic health and udder health lay in the feeding area (homogenous feeding without a huge variation in body condition in lactation and dry period) and... |

| Keskkonnasõbralik umbrohutõrje maheviljeluses koosneb viljavaheldusest, äestamisest, vaheltharimisest, multšimisest, liblikõieliste kasvatamisest külvikorras ja vahekultuuride (sh talviste kattekultuuride) kasvatamist (Thorup-Kristensen jt., 2003). Käesoleva uurimisega seotud varasemad tulemused näitasid, et talvistest vahekultuuridest rukis osutus umbrohtudele kõige kahjulikumaks, pärssides umbrohuseemnete idanevust. Mõnevõrra vähem toimis raihein, mida oli märgata järgnevates kultuurides - herne ja odra umbrohutaimede tiheduses (Barberi jt., 2014). Lisaks kasvutihedusele vähendasid talvised vahekultuurid ka umbrohtude biomassi (Madsen jt., 2015). Väiksem umbrohtude arvukus ja biomass mõjutavad ka mulla umbrohuseemnete varu.

| Gulerod (Daucus carota L. subsp. Sativus (Hoffm.) Thell) er en toårig plante og reproduktiv vækst (frøproduktion) sker efter en periode med kort daglængde og lav temperatur (vernalisering). I grønsagsproduktionen (1. år) tilskyndes hurtig rodvækst og gulerodens udvikling frem til færdigt produkt kan gennem- føres i en relativ kort vækstsæson. Frøproduktion (2. år) af gulerod kræver derimod en lang vækstsæson, hvor frøene modner på planten typisk i august-september. Før i tiden blev frø af sent modnende arter såsom gulerod og kål produceret i Danmark, men i dag foregår denne produktion fortrinsvis i Frankrig og Italien, fordi man dér undgår den sene, våde høst, der kan forringe frøkvaliteten, særligt på grund af svampeangreb. I 1980'erne blev forhold... |

| Ethnoveterinary surveys are missing for wide areas of Europe. During the years 2011 and 2012 80 farmers on 64 farms in seven cantons of Northern Switzerland (Aargau, Zürich, Schaffhausen, St. Gallen, Thurgau, Appenzell Innerhoden and Appenzell Ausserrhoden) were interviewed. More than 500 homemade herbal remedies (HMHR) were documented regarding the used plant species, modes of preparation, dosage, routes of administration, category of use and origin of knowledge. A selection was made by choosing all HMHR which (a) contain only one herbal drug, (b) are used to treat skin alterations and wounds, (c) were administered to the skin, (d) were obtained from forefathers and relatives and (e) have been used by the interview partners themselves at least 5 times... |

| Surface mulch is an important factor of soil protection technology in the cultivation of potatoes. Presented herein are the results of three years (2009–2011) of field trials at two sites (Leškovice and Uhříněves), where two cultivars (Finka and Katka) were grown. Three mulching treatments (grass mulch after planting, grass mulch before germination and black polypropylene mulch textile) were used in the study. The weight of marketable tubers (tuber over 40 mm) and tuber size distribution were influenced significantly by mulching. The application of grass mulch on surface of the row ensured a 20.5–24.8% increase of weight of marketable tubers and higher occurrence of tubers over 56 mm (resp. tubers 56–60 mm and over 60 mm). There was no consistent effect of... |

| En kløvergræsmark indeholder store mængder forholdsvis let omsætteligt kvælstof. Det giver selvfølgelig en god eftervirkning med højt udbyttepotentiale i den efterfølgende afgrøde. Men det giver også stor risiko udvaskning af kvælstof, når en kløvergræsmark pløjes. Udvaskning af kvælstof bør undgås af hensyn til grundvandet, men også af hensyn til den tilgængelige kvælstofmængde på bedriften. Kvælstof, der forsvinder ud af rodzonen, er ikke længere tilgængeligt for afgrøderne! |

| The most common animal health problem in organic dairy production is mastitis. It is considered to be one of the most serious welfare problem in dairy production, as well as an economic problem as it often leads to a reduced milk yield and reduced profit. To combat this problem, the focus in organic dairy production is laid on management strategies to e.g. reduce the use of antibiotics and improve the animal health and welfare. In 2015, the EU-funded project OrganicDairyHealth started in seven European countries, including Sweden. Within the project, an extensive survey on housing, management, health and production was sent out to organic dairy farmers in each country, and this thesis is based on the data from the Swedish survey. This master thesis’ aim... |

| In Nordic conditions, soils are frozen during winter, affecting the decomposition rates of crop residues. Hence, the decomposition rates of above- and underground biomass and the dynamics of the N and C released into the soil were studied in trials focused on green manure crops. The decomposition of the residue and N release from the residue varied among the five species of legume tested. There was a marked difference in decomposition rates between shoots and roots, which may also be explained by the differences in the chemical composition of the residue. The shoot residue decomposes rapidly and it serves as a source of N for the subsequent crop. The root residue decomposes more slowly and this had a positive effect in a crop rotation in the second year.... |

| Results from field experiments in 2000 and 2002 showed that intercropping of perennial ryegrass and green manure legumes prolonged the time for nitrogen accumulation in the grass seed crop. The effect on the grass seed yield was dependent on the green manure legume species. However, using the intercropping technique it was possible to achieve seed yield at 1012 kg ha-1 in 2000 and at 829 kg ha-1 in 2000, which is very promising for the future organic seed production of perennial ryegrass. |

| The core task of sustainable milk production is the conversion of forage into milk, dairy products and, as a by-product, into meat. In Europe and North America, for decades dairy cows were selected for a high genetic merit for milk production under high input farming conditions. It is therefore questionable whether these "high input genotypes" are suitable for forage-based, organic farming systems. The objective of this study was to compare two cow types concerning their suitability for an Alpine organic, low input dairy production system. The cow types used were conventional Brown Swiss (BV) on the one hand and a specific strain of Holstein Friesian (HFL), selected for lifetime performance, on the other. Both cow types were managed within one herd in an... |
