| Organic livestock farming has grown in Wales in recent years. It is focused on producing animals from a predominantly forage-based system, with an emphasis on maintaining animal health through improved welfare and a reduction in the use of routine, conventional veterinary treatments. Breeding and feeding are important factors of the health and welfare of farm animals in organic systems. The guidelines of EU regulation (EC) 1804/1999 address the issue of sourcing of (breeding) stock. Moreover, only activities such as the use of genetically modified organisms (GMOs) and embryo transfer are excluded, and few provisions are included that concern breeding. A number of breeds used in conventional farming could be considered as ’high maintenance’ animals... |

| In this study, we attempt to assess the Danish organic dairy farmers' acceptance of the economic values derived from a stochastic, bio-economic model. We expect the results to show that farmers give increased priority to some traits above the objectively derived economic vaule. |

| The aim of this field study was to investigate interactions between gastro-intestinal nematode (GIN) infection, milk performance and age in goats in order to identify animal groups with higher susceptibility to GIN. On 3 farms (farm A: n = 29, farm B: n = 33, farm C: n = 117 milking goats) fecal egg count reduction tests (FECRT) were performed in summer. All 179 milking goats were enrolled in FECRT and individual milk performance was recorded before and after FEC for FECRT. Furthermore, in early summer and autumn bulk fecal samples were cultured for every farm and GIN genera were determined. |

| Das hier beschriebene Verbundvorhaben umfasst folgende Teilprojekte: FKZ 15NA023, 15NA085, FKZ 15NA086, FKZ 15NA087. Alle in Organic Eprints archivierten Projektbeschreibungen und Veröffentlichungen zu diesem Verbundvorhaben finden Sie unter folgendem Link: http://orgprints.org/id/saved_search/1636. Die Schweineproduktion in Deutschland steht im Konflikt zwischen einer am Tierwohl orientierten Produktionsweise und der Sicherung einer nachhaltigen Wettbewerbsfähigkeit. Der Zielkonflikt zeigt sich beispielhaft am Problem des Schwanzbeißens, das unter den in der Praxis existierenden Haltungsbedingungen regelmäßig ein massives Problem für das Tierwohl darstellt, insbesondere sofern auf eine präventive Teilamputation des Schwanzes verzichtet wird.

| Zusammenfassung Analog zum Ökologischen Gesamtzuchtwert (ÖZW) für Bullen wurde Ende 2008 erstmals ein ÖZW für Kühe berechnet und den ökologischen Milchviehbetrieben in Bayern mit dem Jahresabschluss der Milchleistungsprüfung zur Verfügung gestellt. Der ÖZW unterscheidet sich vom konventionellen Gesamtzuchtwert (GZW) hauptsächlich durch die deutlich stärkere Gewichtung der Fitnessmerkmale. Während bei der Zucht nach GZW der erwartete Selektionserfolg überwiegend in der Milch- und Fleischleistung liegt, wird bei der Selektion nach ÖZW, neben einer moderaten Verbesserung der Leistung, eine deutliche züchterische Verbesserung der Fitnessmerkmale angestrebt. Der ÖZW für Kühe sowie die Teilzuchtwerte Leistung und Konstitution ermöglichen dem ökologisch... |

| Ziel der vorliegenden Studie (Teil eines größeren Projekts zum Zweinutzungshuhn) war eine kombinierte Stations- und Feldprüfung mit Bezug auf die Leistungen der männlichen Tiere. Neben den Leistungsparametern wurden etliche Tierschutzindikatoren erhoben, da die Tiergerechtheit für den Ökolandbau eine große Bedeutung hat. Die Herkunft Bresse hatte die besten Mast- und Schlachtleistungen, die Tiere wurden aber bzgl des Gefieders schlechter bewertet und waren weniger aktiv. |

| According to EU-Regulation 889/2008 slow growing strains shall be used in organic farming in order to ensure good broiler welfare. We examined effects of growth speed on broiler welfare in four different strains (33.01±5.8 to 44.02±8.0 g/day) in two batches on nine organic farms that kept two to four strains in parallel. The currently common slow growing strain (44.02±8.0 g/day) was a reference on all farms. In total 5593 broilers in 36 groups with 30 to 565 animals were kept. Live weight, lameness, skin and plumage condition and cleanliness of plumage were investigated on samples of 30 to 81 birds depending on group size. If possible, measures were taken repeat-edly (twice), at an average body weight of 1800 g to 2600 g. Individual data were analyzed... |

| Regarding access to breeding material for laying hens to organic egg production the following can be concluded: The breeding material available is genetically adapted to the cage systems. This cage adapted material has a shortcoming regarding behaviour in larger flocks that manifest in: too high tendency to feather pecking and cannibalism, and, independent of flock size, also to many mislaid eggs. Experiments has shown that feather pecking, cannibalism and nesting behaviour can be improved by selection. A search for alternative breeds/hybrids has not yet given the ideal "Organic hen". There seem to be a possibility for adaptation of laying bird to diets with lower crude protein that makes a production possible based on "home grown" crops even in Northern... |

| Anders als bei Rindern und Schweinen ist die künstliche Besamung (KB) in der deutschen Ziegenzucht bislang ein kaum übliches Verfahren. Hauptursachen dafür sind der Umfang und die Strukturen der Zuchtpopulationen sowie die wirtschaftlichen Rahmenbedingungen für die Züchter. Andere Länder wie Frankreich, Schweiz, Spanien oder auch Schweden zeigen jedoch, dass durch konsequente Besamungszucht der züchterische Fortschritt erheblich gesteigert werden kann. Durch den Spermaeinsatz verschiedener Vatertiere kann wirksam der Inzuchtproblematik im Bestand begegnet werden. Gerade Halter kleinerer Bestände können so ohne eigenen Bock, dessen Geruchsbelästigung nicht zu unterschätzen ist, ihre Herde optimal reproduzieren. Ein genauso wichtiges Argument für die... |

| This study investigated the effect of, and interactions between, US Brown Swiss (BS) genetics and season on milk yield, basic composition and fatty acid profiles, from cows on low-input farms in Switzerland. Milk samples (n = 1,976) were collected from 1,220 crossbreed cows with differing proportions of BS, Braunvieh and Original Braunvieh genetics on 40 farms during winter-housing and summer-grazing. Cows with more BS genetics produced more milk in winter but not in summer, possibly because of underfeeding potentially high-yielding cows on low-input pasture-based diets. Cows with more Original Braunvieh genetics produced milk with more (i) nutritionally desirable eicosapentaenoic and docosapentaenoic acids, throughout the year, and (ii) vaccenic and... |

| The aim of this study was to estimate genetic parameters and accuracies of breeding values for a set of functional, behavior, and conformation traits in Brown Swiss cattle. These traits were milking speed, udder depth, position of labia, rank order in herd, general temperament, aggressiveness, milking temperament, and days to first heat. Data of 1,799 phenotyped Brown Swiss cows from 40 Swiss dairy herds were analyzed taking the complete pedigree into account. Estimated heritabilities were within the ranges reported in literature, with results at the high end of the reported values for some traits (e.g., milking speed: 0.42±0.06, udder depth: 0.42±0.06), whereas other traits were of low heritability and heritability estimates were of low accuracy (e.g.,... |

| Im Frühjahr 2001 wurde am Institut für ökologischen Landbau der FAL im Rahmen der Diplomarbeit von Dipl.-Ing. agr. Maren Neumann die Bedeutung der Haltung von gefährdeten Nutztierrassen auf ökologisch wirtschaftenden Betrieben in Schleswig-Holstein untersucht. Dazu wurden insgesamt 154 (49%) der 316 ökologisch wirtschaftenden Betriebe mit Hilfe eines standardisierten Fragebogens telefonisch zum Thema befragt. Festzuhalten ist, dass ökologische Betriebe, die gefährdete Nutztierrassen halten, dieses nicht nur aus ideelen Gründen (z.B. zur Erhaltung regionaler Rassen oder Förderung der Artenvielfalt), sondern auch aus Qualitätsgründen handhaben. Dabei werden besonders Robustheit, gute Muttereigenschaften, gute Tageszunahmen und weniger Stressanfälligkeit... |

| In this series of 12 technical leaflets we are presenting a selection of results and recommendations of the work undertaking in SOLID aimed at those working in the organic and low-input dairy industries. An overall introduction provides a short overview of the SOLID project and the work on innovation through stakeholder engagement (WP1). The results presented in the technical notes are derived from the participatory research but also from more traditional scientific experiments carried out as part of the SOLID project. The technical notes cover three thematic areas which we believe are particularly important for organic and low-input farming: Five notes are related to the feeding of ruminants with forage based diets and home-grown feeds, three notes... |
