Introduction: Mycotoxins are toxic compounds produced by the secondary metabolism of toxic moulds in the Aspergillus, Penicillium and Fusarium genera occurring in food commodities and foodstuffs. The range and potency of mycotoxins make this group of naturally occurring toxins an ongoing animal health hazard and a constant risk for contamination of the food supply. Mycotoxicoses are diseases caused by exposure to foods or feeds contaminated with mycotoxins. Mycotoxins exhibit a variety of biological effects in animals, such as liver and kidney toxicity, central nervous system effects or estrogenic effects. There are differences between animals with regard to the susceptibility towards different mycotoxins. Poultry secrete mycotoxins relatively fast... |

Organic poultry production has substantially increased in the last few years. On organic farms, welfare of poultry is enhanced due to enriched housing conditions as access to a free range area. This may reduce feather pecking and keep the health status at least on the same level as on conventional farms. However, welfare of organic poultry may be further improved if: (a) laying hens are already reared in enriched systems that are close to the systems in the layer house, (b) a frequent and even use of the run, (c) selection of suitable genotypes especially in relation to digestive ability, and (d) effective prevention and control of parasites. |

Der Infektionsdruck (PAD: Potentielle Ascosporen Dosis) beschreibt die Anzahl Ascosporen, die für die Primärsaison pro m² Anlagenboden erwartet werden kann. Sie wird durch den Befall zum Zeitpunkt des Blattfalles bestimmt und kann in behandelten Praxisanlagen zwischen einigen Hundert und über 100 Millionen erreichen, also um einen Faktor von mehr als 1 Million schwanken. Von diesem Gesamtbefall zum Blattfall entstehen in Anlagen mit einem höherem Primärbefall mindestens 80% ab etwa Mitte bis Ende August auf den oberen Blättern der Langtriebe. |

The experiments were carried out in the Eerika test site of Rõhu experimental station of Institute of agricultural and environmental sciences, Estonian University of Life Sciences in 2012–2016. There were 5 succeeding crops in rotation: red clover, winter wheat, pea, potato and barley undersown with red clover. Four cropping systems were studied. The objective of present research was to investigate the effect of cropping systems on the yield components of potato and on the quality parameters of tubers. Another target was to study the effect of potato cropping systems on the soil nutrient content. The results of the 5 year study revealed that the cropping systems did not have any significant effect on the formation of potato yield components and the... |

In contrast to the increasing demand for dairy goat products in Germany, a market for goat kid meat as a related product is more or less non-existing. Thus, the objective of our study was to develop a concept for organic goat kid meat production for dairy goat farms. In collaboration with a wholesaler, organic dairy goat farmers and marketing research the experimental part of our study was to find out if cross-breeding of meat-goats could improve meat quality and performance of fattening goat kids together with other factors like concentrate ratio of the diet, housing system as well as raising strategy. First results indicate that a low input level of concentrates of 10 % of total dry matter intake per goat kid and year is not sufficient to meet the... |

Equine Sarcoid (ES), a semi malignant skin tumour, is the most common neoplasia of horses (Marti et al.1993). There is no generally effective single treatment existing and the recurrence rate is high (Martens et al.2001). Furthermore as a treatment obstacle, Sarcoids tend to occur as multi-focal tumours or can be found in critical locations (peri-ocular) where success of surgical interventions is very limited (Carstanjen et al.1997). Due to encouraging results in human medicine and small animals practice after adjuvant cancer treatment by mistletoe extracts (Biegel et al.2007) the viscum therapy could hypothetically fill a therapy gap for equine tumour diseases as well. Hence, goal of this clinical trial was to evaluate the safety and efficacy of Viscum... |

Pollen beetle (Meligethes spp.) is a major yield-limiting factor in organic oilseed production. Currently there are no effective methods available to control this beetle in organic agriculture. From 2006 to 2008 work was carried out at Agroscope ARTReckenholz to find suitable organically compatible plant protecting agents which are effective against the beetle. A partial reduction in beetle infestation was observed when liquid manure, lavender oil and rapeseed oil was applied. Dusting agents such as ash and substances containing silicate (stone meal) were very efficient, almost completely removing the beetle after application. However, beetle infestation increased again after one or two days following application. Dusting substances in combination... |

On-farm nitrogen fixation is a driving force in organic agriculture. The efficiency with which this nitrogen is used can be increased by using lucerne (Medicago sativa) or grass-clover directly as sources of fertilizer on arable land: cut-and-carry fertilizers. In two arable crops, the use of lucerne and grass-clover as fertilizers was compared with the use of poultry manure and slurry. The nitrogen-use efficiency at crop level was comparable or better for the cut-andcarry fertilizers as compared to the animal manures. The relative P and K content of these fertilizers came closer to the crop demand than that of the poultry manure. Crop yields were comparable or better when using lucerne or grass-clover as fertilizer. It is concluded that cutand-carry... |

The empirical analysis of the historical development of transdisciplinary co-production of knowledge (CPK) in organic agriculture (OA) in Switzerland has revealed three distinct phases. The initial phase shows various characteristics of transdisciplinary CPK and a high importance of experiential knowledge. The 2nd and 3rd phases involve an in-creasing segregation of farmers’, extension agents’, and scientists’ knowledge, caused by internal and external impacts, i.e. foundation of independent research institutions, changes in agriculture policy, and new market strategies. These developments strikingly represent an ambiguous trend: the growing societal and political recognition of OA and the increasing market, which are positive achievements, are... |

Phosphogypsum from Siilinjärvi plant were tested in soil incubation-leaching-studies(I), and in liquid pig manure treatment (II) in farm pit. In soil columns, gypsum additions significantly reduced erodibility and ortho-P concentrations in the leaching water. In the pig manure test, the gypsum-based precipitate fractionated phosphorus to P-rich sediment and to almost P-free upper part. Upper low-P fraction represented 2/3 of the total manure volume. |

According to the results, the selected special crops may attract pollinators such as honeybees and flower flies more than conventionally cultivated crops. Also, the number of weed species among special crops may be higher than the number of weeds identified among barley and timothy. The high amount of dry weight and weed species among the special crops may be due to the challenges of herbicide treatments. These results may be used when strategies for more diversified cropping systems, where selected special crops could be cultivated as a rotation with conventionally corps, are planned. |

The demand for organically cultivated oil seed rape in Germany is very high. But the risk of cultivation due to the high demand of N-supply, preceding crop, weed manage¬ment and plant protection is very high as well. In a two-year experiment, the effects of (I) preceding crop (ryegrass-clover-mixture: (a) cut mowing vs. (b) mulching, (c) peas and (d) barley-pea-mixture), (II) row distance of oil seed rape (12.5 cm, 25 cm, 37.5 and 50 cm) and (III) underseed in autumn together with the oil seed rape (with and without white clover) were tested in a split-plot-design with four replicates at the ex-perimental farm of the Institute of Organic Farming (FAL) in Trenthorst. The results showed a very different yield level with 0.85 t ha-1 in 2004, and 1.68 t ha-1... |

A field trial with carrots was carried out in 1998 at two sites in Hesse (North: loamy soil in Neu-Eichenberg; East: sandy soil in Queck) to compare 6 open pollinating and 6 F1 hybrids under an Organic Farming regime. Characteristics of cultivation, harvest, quality, and longevity were measured. Of the parameters of cultivation and harvest the hybrids showed a more intensive foliage growth, higher marketable yields (plus 29 and 25%), and more homogeneous taproots than the open pollinating cultivars. Picture forming methods clearly separated the samples into the two groups of breeding methods. The open pollinating cultivars were characterized by higher degrees of form intensity and ripeness and a stable vitality. The hybrids of the sandy site had a better... |
