Effekte verschiedener Aufzuchtmethoden von Ziegen auf Gesundheits-, Leistungs- und Verhaltensparameter Organic Eprints
Plakolm, Isolde; Reiber, Christoph; Glasser, Tzach; Honig, Hen; Valle Zárate, Anne; Chagunda, Mizeck.
Die Auswirkungen von Ziegen-Kitz-Trennung und Absetzen auf die Gesundheit, Leistung und Verhaltensparameter wurden in drei Aufzuchtsystemen untersucht: 1) Kitze, die Muttermilch trinken, 2) Mutter-Kitz-Trennung und Konsum von Milchersatz, 3) und Kitze, die sowohl Muttermilch als auch Milchaustauscher konsumieren. Das Körpergewicht, die Morbidität und der Milchaustauschkonsum wurden für die Kitze gemessen, und die somatische Zellzahl in der Milch, die Milchleistung, die Morbidität, die Anzahl der Schritte, die Positionsänderungen von Stehen zu Liegen und die Liegezeit für Ziegen. Pp Trennung führte zu einer niedrigeren Variabilität der somatischen Zellzahl innerhalb der Gruppe und zu einer niedrigeren Anzahl kranker Mütter. Jedoch führte pp Trennung bei...

Ökologische und konventionelle Milchviehhaltung im Vergleich: Haltungsbedingungen, Tierwohlindikatoren und Leistung von Fleckvieh und Holstein Kühen Organic Eprints
Reiber, Christoph; Baisch, Philipp; Chagunda, Mizeck; Valle Zárate, Anne.
Diese Studie untersuchte den Einfluss des Betriebstyps (ökologisch vs. konventionell) und der Rasse (Fleckvieh vs. Holstein) auf die Haltungsbedingungen und das Management und Leistungs- und Tierwohlindikatoren anhand von Interviews und Betriebsmessungen. Ferner wurde die Wahrnehmung von Tierwohlindikatoren durch die Landwirte evaluiert. Kühe auf Biobetrieben hatten mehr Weideauslauf und waren weniger häufig enthornt als Kühe auf konventionellen Betrieben. Das Haltungssystem und die Rasse hatten einen signifikanten Einfluss auf die Milchleistung. Obwohl kein signifikanter Einfluss des Betriebstyps und der Rasse auf Mastitis- und Lahmheitsindikatoren festgestellt wurden, zeigten die Ergebnisse einen geringeren Einsatz und niedrigere Kosten einer...

Breeding for resistance to nematode infections in organic goat production in Germany – A way forward? Organic Eprints
Muth, PC.; Tietgens, G.; Pöhlmann, I.; Reiber, Christoph; Valle Zárate, Anne.
Organic goat production in Germany could benefit from genetic improvement strategies that take the resistance of goats to nematode infestations and the resilience and tolerance for infections into consideration. However, there still is an immense research need before such traits can be incorporated in a breeding program.

Organic and alike farming in Latin America: state and relevance for small-scale livestock keepers Organic Eprints
Siegmund-Schultze, Marianna; Valle Zárate, Anne.
While the organic movement is growing, its contribution to small-scale livestock farm-ing in Latin America is contentious. Secondary literature and available statistics were used for this study. Farms and area under certified organic agriculture are rising, but small-scale livestock farming is little represented. The latter is yet to be found in non-certified organic-like farms, offering locally adapted paths to securing livelihoods.

Situationsanalyse süddeutscher Erwerbsziegenhalter Organic Eprints
Herold, Pera; Keller, Monika; Valle Zárate, Anne.
Dairy goat keeping is a growing business in Germany since the 1980ies. So far, there is little knowledge on the structure of these goat farms and their husbandry and breed-ing management. Aim of this study was to get an overview on dairy goat husbandry and breeding in Baden-Württemberg and Bavaria. For this, a structured questionnaire was developed to investigate operational characteristics and basic data on dairy goat husbandry and breeding. The addresses of commercial dairy goat farms where ob-tained from goat breeders associations. The feedback from goat farmers was very high (94%). Most dairy goat farms are organic farms and belong to specific certifying organisations. Most farms (87%) farm less than 50 ha of agricultural land and keep between 60 and...

Zuchtprogramme ohne Biotechnologie - Etablierung von Bockringen in der Ziegenzüchtung Organic Eprints
Herold, Pera; Bürstel, Daniela; Domes, Ursula; Spengler, Dieter; Mendel, Christian; Wenzler, Johann-Georg; Rogg, Rudolf; Hamann, Henning; Valle Zárate, Anne.
Within organic livestock farming, the use of AI versus natural mating is under steady discussion. However, no special organic breeding programs without AI are set in place so far. The present study takes goat breeding in Germany as an example to show how an organic breeding program without biotechnology could be organised. As basis, breeding planning on different breeding plans is carried out: the breeding program in place, a breeding program with buck rotation within “buck circles” and a breeding program with AI are evaluated. It can be shown that within smaller populations (here: goat breeding in South Germany) a buck rotation scheme with progeny testing is superior in genetic gain than the actual and a breeding program based on AI. In a second step, in...

The influence of farm and herd factors on the health status of organic dairy cattle under low concentrate feeding considering an assessment-tool for siterelated breeding Organic Eprints
Selle, Margret; Ivemeyer, Silvia; Spengler Neff, Anet; Reiber, Christoph; Valle Zárate, Anne.
The objectives of this study were to examine influences of farm and herd factors on the health status of Swiss organic dairy cattle and to evaluate if an existing estimation tool is suitable to express impacts of not-site-related breeding on herd health and reproduction indicators in 72 organic dairy farms with low concentrate feeding. Farm and herd factors were body condition scores, milk recording data, and farm management characteristics. Data from an existing estimation tool to describe farm and cow ‘types’ and the site-relatedness of breeding was also included. Health status was assesses by herd means of calving interval, fat-to-protein ratio, somatic cell score, veterinary treatments, culling rate, and number of lactation. A relation between the...
