| Die Kombination von Weidehaltung mit automatischen Melksystemen (AMS) stellt besondere Herausforderungen an das Betriebs-, Fütterungs- und Weidemanagement. In der vorliegenden Arbeit wurden Ergebnisse und Erfahrungen von 10 österreichischen Bio-AMSWeidebetrieben erfasst. Der Kuhbestand der Betriebe war mit 36 Kühen gering, die AMS-Auslastung lag im Mittel bei nur 44 % (26 bis 60 %). Die Betriebe stockten den Kuhbestand nach Umstellung auf AMS auf und reduzierten das Weideangebot leicht (-12 %), jedoch wurden hier große Streuungen festgestellt (-50 bis + 60 %). Bei der Entscheidung auf das AMS umzustellen waren arbeitswirtschaftliche Überlegungen wichtiger als ökonomische Gesichtspunkte. Die Melkfrequenz lag mit 2,4 Melkungen pro Kuh und Tag während der... |

| Die zukünftigen Rahmenbedingungen lassen eine steigende Ressourcenkonkurrenz zwischen Nahrungs- und Futtermittelproduktion erwarten. Gerade die Rindermast wird in diesem Zusammenhang sehr oft kritisch betrachtet. Das Ziel der vorliegenden Arbeit war es daher, unterschiedlich intensive Rindermastsysteme hinsichtlich ihres Ackerflächenbedarfs und ihres Beitrags zur Netto- Lebensmittelproduktion zu untersuchen. Die Analysen beruhen auf Daten eines Mastversuchs mit Kalbinnen, Ochsen und Stieren der Rasse Fleckvieh auf Grassilage- bzw. Maissilagebasis. Die Tiere der Grassilagegruppen wurden auf drei unterschiedlichen Kraftfutterniveaus (extensiv, niedrig, hoch) und die Maissilagegruppen auf hohem Kraftfutterniveau gemästet. Die... |

| To investigate the effect of feed transition from barn feeding to pasture on the course of ruminal pH a study with 8 lactating dairy cows was undertaken. Therefore, an indwelling pH-measurement and data transmitting system was used. The experiment started at 27th March 2012 and a gradual transition from barn feeding to pasture feeding was done (periods P1-P6). After 7 days of barn feeding (P1) animals were given pasture progressively with increasing grazing time from 2 to 7 h/d (P2, day 8-14). In P3 (day 15-21) the cows spent 7 hours/d on pasture. Beginning on day 22, animals had 20 h/d access to pasture (continuous grazing), only semi-daily interrupted for 2 hours for milking and additional feeding (P4-P6). During the barn feeding period (P1), average... |

| The aim of this study was to highlight the economic importance of longevity in organic dairy cattle husbandry. Performance and reproductive data of 44,976 Austrian organic Simmental dairy cows were analysed by applying a bio-economic model. A farm scenario as well as different market situations were modelled. Overall costs declined with increasing longevity, due to dropping replacement costs. Annual profit was influenced considerably by milk yield and longevity. Short-lived animals needed substantially higher annual milk yields than long-lived animals to achieve equal annual profits. The applied market scenarios showed an increasing importance of longevity in situations of increasing economic pressure (+20% of concentrate price). It has been proven that... |

| Milk composition of dairy animals is influenced by the composition of the ration fed. The objective of this study was to determine if the percentages and absolute amounts of hay, grass silage, pasture, maize silage and concentrate in the feed ration can be estimated using MIR spectrometry of milk. A total of 10200 milk samples from 90 dairy cows were collected, and the intakes of all ration components were measured. Using partial least squares regression (PLS), equations were developed to estimate ration compositions corresponding to each milk sample. To evaluate accuracy, the correlation between observed and estimated values (R) and ratio to performance (RPD) were used. Notable R values (for kg/for %) were observed for the ration proportion of pasture... |

| 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... |

| Bei der Koppelweidehaltung ist die angestrebte Aufwuchshöhe am ersten Auftriebstag eine entscheidende Größe für die Anzahl an benötigten Koppeln. Welchen Einfluss unterschiedliche Zielaufwuchshöhen auf den Jahresertrag und den Graszuwachs haben wurde auf einer Dauerweidefläche am Versuchsbetrieb des Instituts für Biologische Landwirtschaft und Biodiversität der Nutztiere am Lehr- und Forschungszentrum für Landwirtschaft Raumberg-Gumpenstein im Vegetationsjahr 2013 untersucht. Dabei wurden 3 unterschiedliche Höhen (niedrig, mittel und hoch) miteinander verglichen und die Erträge mittels Weidekörben gemessen. Dabei erzielte die niedrige Wuchshöhe (10.343 kg TM/ha) einen signifikant geringeren Jahresertrag gegenüber den mittleren (12.119 kg TM/ha) und hohen... |

| Dairy cow strains arising from conventional breeding programmes are frequently perceived as unsuitable for organic and low input milk production systems. While farmers have identified a number of breeds and strains as being ‘adapted’ to organic and low input systems, there is often little scientific evidence to indicate that these breeds are more appropriate than conventional genotypes. Thus the purpose of this study is to examine the response of different dairy genotypes (i.e. "conventional" versus "adapted") to an undersupply with nutrients and energy, which is a characteristic of low input systems with limited dietary supplementation and to provide information on the metabolic response of dairy cows to such dietary restrictions. |

| In the present study basic data was collected from eight organic dairy farms where no concentrates were fed (KF0). This data (from 2010 and 2011) was compared with results from about 140 Austrian organic dairy farms included in a federal extension program. The 140 farms were divided into three groups, depending on the amount of concentrate fed per cow and year (KF1: up to 975 kg, KF2: 976-1,400 kg, KF3: more than 1.400 kg). The ECM yield increased from 5,093 kg in KF0 to 6,828 kg in KF3. Calculated forage milk yield decreased by increasing concentrate supplementation from 5,093 kg (KF0) to 4,412 kg (KF3). Data related to animal health did not significantly differ between the four groups. However the calving interval was longer in KF0 but non-return-rate... |

| Sward height is a key parameter for rotational grazing. Influence of different sward heights (low: 8 cm, medium: 10 cm, high: 12 cm) on DM yield and grass growth rate were investigated on an intensive grazed area at the research farm of the Organic Institute of AREC Raumberg-Gumpenstein during the vegetation period of 2013. The significant highest yields were found in treatment “high” (12,581 kg DM ha-1) and “medium” (12,119 kg DM ha-1). Treatment “low” reached a yield of 10,343 kg DM ha-1. During summer, grass growth rate was about 60 kg DM ha-1 day-1 in average. |

| In einer dreijährigen Schweizer Systemstudie wurden die Milchproduktionssysteme Stall- (SH) und Vollweidehaltung (VW) auf einem geteilten Versuchsbetrieb hinsichtlich produktionstechnischer, ökonomischer und ökologischer Aspekte verglichen. In der vorliegenden Arbeit wurden darauf aufbauend die Milchproduktionssysteme SH und VW hinsichtlich ihres Beitrags zur Netto-Lebensmittelversorgung untersucht. Je nach Berücksichtigung an für den Menschen verwertbaren Nährstoffen in den Futtermitteln produzierte das System VW über die tierischen Produkte zwischen 6,6 bis 11,2 mal mehr für den Menschen verwertbares Protein und 3,5 bis 6,6 mal mehr verwertbare Energie als die Tiere über das eingesetzte Futter verbrauchten. Für das SH-System waren diese Faktoren deutlich... |

| Schwefel ist ein wichtiger Pflanzennährstoff und die Immissionen aus der Atmosphäre gingen seit 1980 stark zurück. Unter diesen Rahmenbedingungen wurde der Einsatz eines elementaren Schwefeldüngers ("Sulfogüll plus" von BvG) auf einer 4-schnittigen Dauerwiese getestet. Vier Schwefeldüngungsstufen von 0 (S0), 30 (S30), 60 (S60) und 90 (S90) kg S/ha stellten die Varianten dar. Variante S60 und S90 erreichten die signifikant höchste TM- (S60 10.779 und S90 11.073 kg/ha) XP- (S60 1.749 und S90 1798 kg/ha) und Energie-Erträge (S60 64.008 und S90 65.370 MJ/ha) im Vergleich zur Variante S0 (TM: 9.947 kg/ha, XP: 1.569 kg/ha, Energie: 58.434 MJ NEL/ha). Ein Ziel der Bio-Landwirtschaft ist, möglichst viel Eiweiß aus dem Grünland zu gewinnen. In diesem Fall dürfte... |

| Poa pratensis is one of the most important grass species in Alpine region with a high protection against weed infestation. The most difficulties for an establishment in permanent grassland are a steady juvenile growth and a low competitive strength during this time. In a four-year (2008-2011) field trial the establishment of P. pratensis using continuous grazing in permanent grassland was investigated at the organic grassland and dairy farm of the AREC Raumberg-Gumpenstein. Variant 1 was used under a three times cutting management. During two years of continuous grazing (2008-2009), variant 2 was treated without reseeding and variant 3 was reseeded with P. pratensis variety BALIN three times (each time with 10 kg ha-1) in 2008. In 2010 and 2011 all three... |

| In Zukunft kann in der Milchviehhaltung eine weitere Differenzierung in der Intensität der Produktion zwischen den Betrieben erwartet werden. Dies muss auch in den Zuchtprogrammen eine Berücksichtigung finden. Der ökologische Gesamtzuchtwert ist ein Hilfsmittel für Milchviehbetriebe welche im Fitnessbereich und der Grundfutterlebensleistung ihren Schwerpunkt setzen und demgegenüber auf Frühreife, hohe Einsatzleistungen und Höchstleistungen verzichten möchten. In Österreich besteht von Bio-Austria und vom Bio-Institut des LFZ das Bestreben, den ökologischen Gesamtzuchtwert entsprechend dem Bayrischen Modell vollständig zu etablieren. Derzeit können die ÖZW-Zuchtwerte von Zuchtstieren für die Rassen Fleckvieh, und Braunvieh über die Homepage des... |

| 8 % of the total EU population lives in mountainous areas which represent a particularly important eco-region in Central Europe. Because of ecological, climatic and economic reasons an increasing pressure is imposed upon agriculture. Hence in large parts of European mountainous areas drastic changes in agricultural structure and land use systems can be observed in terms of emigration and land abandonment. Due to disadvantaged production conditions, and the high ecological sensitivity, organic farming is an important option for a sound regional development. In alpine regions organic farming does not proceed in a homogeneous way. One essential reason for that could be seen in the differences of national and regional “traditions and orientations” and... |
