Analyse des Energieeinsatzes und der Energieeffizienz bei der Futtererzeugung in der Milchviehhaltung Organic Eprints
Frank, Helmut; Schmid, Harald; Hülsbergen, Kurt-Jürgen.
Fodder production requires the highest energy input in dairy farming. Taking the organic and conventional dairy farms from the project “climate effects of land use systems – evaluations on pilot farms” as an example we analyse the energy input for producing different fodder types and the influence of feeding strategies in Southern Germany. The results show that grazing is the most energy efficient form of feeding, followed by fresh grass and silage. Hay requires the highest energy input per unit forage energy. Maize silage has a lower energy input due to high yields. The higher the part of roughage in the ration the lower is the energy input for production of the ration.

Modell zur Energiebilanzierung der Milchviehhaltung - Anwendung in Pilotbetrieben Organic Eprints
Frank, Helmut; Schmid, Harald; Hülsbergen, Kurt-Jürgen.
Der Beitrag stellt ein Modell zur Energiebilanzierung der Milchviehhaltung vor, das in der Lage ist, Praxisbetriebe auf einzelbetrieblicher Ebene zu bilanzieren. Die Modellanwendung in ökologischen und konventionellen Betrieben zeigt, dass die ökologischen Betriebe im Mittel einen geringeren produktbezogenen Energieeinsatz je kg Milch aufweisen als die konventionellen Betriebe. Die größten Energieinputs sind die Futterbereitstellung, die Milchgewinnung und die Nachzucht. Insbesondere durch die Wahl der Futtermittel und die Nutzungsdauer der Milchkühe kann die Energiebilanz der Milchviehhaltung beeinflusst werden.

Greenhouse Gas Emissions of organic and conventional dairy farms in Germany Organic Eprints
Frank, Helmut; Schmid, Harald; Hülsbergen, Kurt-Jürgen.
The article presents a model to calculate the greenhouse gas emissions of German dairy farms. The model was tested in 12 organic and 12 conventional farms in Southern and Western Germany. The results show that there is no significant difference between the greenhouse gas emissions per kg milk of the organic and the conventional farms. The lower milk yield of the organic farms is compensated by the lower fossil energy input and the higher carbon sequestration in the fodder production. It can also be seen that a raise of the milk yield from a medium level does not lead to a mitigation of greenhouse gas emissions per kg milk.

Klimagase und deren Minderung bei der Milchproduktion Organic Eprints
Paulsen, Hans Marten; Frank, Helmut; Hülsbergen, Kurt-Jürgen; Rahmann, Gerold; Schmidt, Harald; Warnecke, Sylvia.
Sources of greenhouse gas (GHG) emission of milk production were analysed on organic and conventional dairy farms from cradle to farm gate and resulted in a mean of ca. 1 kg CO2 eq kg ECM-1 independent of the farm system. When calculated according to dry matter intake of the cows, mean percentages of GHG emissions from enteric fermentation on organic or conventional farms were 31 or 42 % from the complete product related emissions from milk production from cradle to farm gate, respectively. When feed quality parameters were considered in calculation, enteric methane production increased considerably with higher fibre contents in feedstuffs. This was especially important at lower milk yields. On the 44 farms that were analysed, minimal potential GHG...

Modelluntersuchungen zu Treibhausgasemissionen der ökologischen und konventionellen Milcherzeugung Organic Eprints
Frank, Helmut; Schmid, Harald; Hülsbergen, Kurt-Jürgen.
A model to analyse the fossil energy input and the greenhouse-gas (GHG) emissions of dairy farms is presented. The model was applied in model farms that base on a set of real dairy farms. The subject of the examination is to identify the major energy inputs and contributing factors to the GHG-emissions of dairy farming. The results show that the fodder production, the milking process and the breeding of heifers are the biggest energy inputs. The main sources of GHG are the fodder production and methane from digestion. Strategies to optimise farming systems and to mitigate GHG-emissions from dairy farms can be derived from the results.
