| 乳牛のビタミンB群製剤の適正な補給を目的に、健康牛（泌乳中期および乾乳期）と新生子牛のビタミンB1、B2、B6、B12の血中濃度を測定した。泌乳中期群(n=5)ではB1、B2、B6、B12の血中濃度は51.2±1.2ng/ml、92.1±3.9ng/ml、37.8±1.7ng/ml、220.2±16.3pg/ml、乾乳期群(n=4)では39.5±3.3ng/ml、75.2±4.6ng/ml、42.6±2.2ng/ml、406.8±48.1pg/mlで、泌乳中期群と比較してB1、B2で低値、B12で高値（p<0.05)を示した。新生子牛群(n=9)では、出生直後のビタミンB1、B2、B6、B12の血中濃度は47.0±3.6ng/ml、169.9±6.7ng/ml、4.1±0.2ng/ml、357.4±44.2pg/mlで、生後20日目では30.0±1.4ng/ml、130.9±6.4ng/ml、16.5±0.6ng/ml、230.4±13.9pg/mlを示し、ビタミンB6を除くビタミンB群の血中濃度は生後漸減した。 以上の成績から飼養状況および個体の状況により血中濃度が異なるため、適正な補給に当たっては対象牛のビタミンB群の血中濃度を把握し、今回の測定値を参考として適量の薬用量の決定が必要であると考えられた。Blood concentrations of the vitamin B complex (B1，B2，B6，and B12) were measured in healthy cows both during the lactation period and during the non-lactation period，and in calves from 1 to 20 days... |

| Toasting field beans can improve the protein quality of field beans markedly. In the feed demonstrations carried out in Project EcoProtein testing a new method of toasting with a drum dryer, showed, however, only reduced effect on the protein quality due to a lower than optimal temperature. The toasted field beans were fed in two organic dairy herds, replacing a part of the concentrates in the ration in a cross-over design. Preliminary results showed no milk yield difference in herd 1, but a reduced milk yield level in herd 2. |

| Regionale Lebensmittel zeichnen sich durch ein hohes Maß an geschlossenen, regionalen Stoff- und Wirtschaftskreisläufe entlang der Wertschöpfungskette (WSK) aus. Sie leisten damit insbesondere auf regionaler Ebene einen Beitrag zur Nachhaltigen Entwicklung und Resilienz. Zur Quantifizierung dieses Beitrags wurde ein Bewertungsmodell entwickelt, welches die Themen regionale Wertschöpfung, regionale und betriebliche Resilienz sowie Produkteigenschaften abdeckt. Bei der Bewertung wird die gesamte Wertschöpfungskette von den landwirtschaftlichen Vorleistungen bis zum point-of-sale mit einbezogen. Das Modell liefert produktbezogene Ergebnisse, die als „regionaler Mehrwert“ bezeichnet werden. Im Folgenden wird das Bewertungsmodell und die damit generierten... |

| Dairy farming is the largest agricultural contributor to greenhouse gas emissions in Europe. In this study, the carbon footprint of organic dairying was evaluated by means of a life cycle assessment, based on real farm data from six European countries: Austria, Belgium, Denmark, Finland, Italy and United Kingdom. A total of 34 farms were analysed. The assessment was carried out using an attributional approach with system boundaries from cradle to farm gate. In relation to dairy production, a functional unit of 1 kg of energy corrected milk was used. The results gave an average of 1.32 kg CO2 equivalents per kilogramme of energy-corrected milk with standard deviation of 0.22, which is consistent with recent studies. The main contributor to this is enteric... |

| Organic dairy milk production is a growing sector in Germany. The sector varies between regions and individual farms due to topographical and structural differences, but very little statistical information is available in Germany about this variation. The aim of this study was to identify typical major farm types (MFT) of German organic dairy farms and to describe their farm, herd and management characteristics. Based on data from 204 organic dairy farms from previous studies with representative samples, four MFT were identified by cluster analysis and expert opinions. Cluster criteria were herd size, milk yield, region and housing system. 10-11 farms per MFT, in total 41 farms were interviewed with respect to their management by phone or during a farm... |

| Organic farming aims to create an integrated, humane, environmentally and economically sustainable agricultural system. For organic dairy systems, the fulfilment of these aims requires the understanding and integration of a number of systems components including land use (mixed or dairy only) and stocking rate; grassland and forage production (including quantity and quality); potential milk yield (and milk quality); animal nutrition (largely farm based) and health; environmental sustainability such as farm nutrient balance; the financial status of the farm (including enterprise performance, fixed costs and labour use and farm income and profit) and finally the policy environment in which organic dairy systems operate. This review discusses worldwide... |

| Fazit Bezogen auf die untersuchte Stichprobe der eingestreuten Laufställe wiesen die ökologischen Betriebe eine durchschnittlich höhere Tiergerechtheit auf. Dies galt jedoch nicht für alle Ein-zelbetriebe. Insgesamt gibt es aber noch viele Biobetriebe, bei denen Verbesserungen der Tiergerechtheit nötig und möglich sind (z.B. Anbindeställe oder Standard-Boxenlaufställe). Die untersuchten Bewertungssysteme zeichnen sich durch eine gute Praktikabilität aus. Je nach System lag die Erhebungsdauer zwischen 30 und 90 Minuten. In Österreich wurde eine hohe Wiederholbarkeit der Beurteilungen zwischen verschiedenen Anwendern ermittelt. Zur Erhöhung der Aussagekraft bezüglich der Tiergerechtheit sollten jedoch mehr tierbezogene Merkmale herangezogen werden, die... |

| Das hier beschriebene Projekt ist Teil eines Verbundvorhabens, das folgende Teilprojekte umfasst: FKZ 09OE012, FKZ 08OE196. Alle in Organic Eprints archivierten Projektbeschreibungen und Veröffentlichungen zu diesem Verbundvorhaben finden Sie unter folgendem Link: http://orgprints.org/cgi/saved_search?savedsearchid=1206 Die Richtlinien des Ökologischen Landbaus fordern den Einsatz trockener Einstreu, die aus Stroh oder einem anderen geeigneten Naturmaterial besteht. Organische Einstreumaterialien können umweltassoziierten Mastitiserregern jedoch optimale Wachstumsbedingungen bieten und somit die Entstehung von Euterentzündungen begünstigen, die durch diese Keime verursacht werden. Das geplante Projekt soll der potentiellen Infektionskette Einstreu –... |

| Loose housing systems are commonly designed for cows without horns. Farmers keeping horned herds are facing increased risks of injuries among the cows. Interviews were carried out on farms with 62 horned dairy herds in order to collect practical evidence on problems and suitable measures related to the keeping of loose housed horned cows. Most farmers see the feeding area, the cubicles and the waiting area before milking as problem areas. A possibility to securely lock all cows in the feeding rack and an easy retreat from the rack is regarded important. The cubicles should offer an exit to the front, which can be used by cows when attacked from behind. Generous space allowances in the waiting area as well as in the whole stable were recommended.... |
