Grazing provides livestock better opportunities to act out their species specific behaviour compared to the restrictive stable conditions. Studies on the effect of grazing on animal welfare in dairy farming in Germany are rare and have not been conducted under the specific conditions of organic dairy farming. The aim of the present study was to examine the effects of grazing on animal welfare of dairy cows in organic and conventional farming based on the Welfare Quality® protocol for dairy cattle. In this paper, we present the initial evaluation of a comparison between zero grazing and summer grazing. The first results indicate an improvement in most welfare principles during the summer months for dairy cows with summer grazing, except for between... |

For reasons of animal health, milk yield and for environmental issues an optimal supply of protein and energy for dairy cows is essential. The aim of this study is to examine potential protein and energy malnutrition and surplus in dairy herds. We present a comparison of the protein and energy supply between 18 conventional and 16 organic dairy herds. Initial results indicate an undersupply on energy in the first one hundred days of lactation in both the organic and conventional feeding regimes. It is easier to provide an adequate protein supply in conventional conditions in the first one hundred days than in organic ones. A balanced supply is guaranteed for a mere 21,3 % of the organic cows. In the second one hundred days this increases to 26,5 %,... |

Mineral phosphorus (P) fertilizers from fossil reserves are finite which puts agriculture at risk of losing soil fertility. This study calculates P soil balances of an organic dairy farm in Northern Germany to focus on potentials and variations in the farm P cycle. P flows were different between the years because yield levels and amount of manure application varied. Different plant species showed different P export which depended mainly on biomass export. This can also be seen as their site specific mobilization potential. The highest mean P export between 2010 and 2012 was measured with maize (mean 30.4, range 17.7-38.2 kg P ha-1 a-1) and grass-clover (mean 23.7, range 17.3-29.5 kg P ha-1 a-1). By grazing, permanent grassland showed a mean P mobilization... |

In the experimental station of the Thünen-Institute of Organic Farming the dairy breeds Holstein-Friesian (SBT) and Red Holstein double usage (RBT) are kept in separate herds under identical conditions. By means of a material flow FARM-Model, designed with the life cycle assessment (LCA) and material flow software Umberto, an assessment from cradle to farm gate of standard environmental impact categories was undertaken. While the BH has a better environmental performance due to higher milk yields the results depend largely on used algorithms in the model. When benchmarking different farms in terms of environmental performance modeling uncertainty has to be taken into account. |

In a network of organic and conventional pilot farms with dairy and/or arable production in Germany (www.pilotbetriebe.de) aspects of sustainability, resource efficiency, animal health and welfare and economic aspects are analysed. This is based on on-farm assessments and on whole farm modelling. In the first interdisciplinary workshops on the project farms results were presented and scenarios were developed in a participatory approach by scientists, consultants and farmers to improve N, P and land use efficiency as well as dairy health and welfare. Typical areas of action to optimize sustainability in these aspects were identified on the farms, e.g., complete accounting of manure N (N balance), enrichment of crop rotations with clover grass and cover... |
