Spatio-temporal patterns of herbage availability and livestock movements: A cross-border analysis in the Chinese-Mongolian Altay
Due to increasing population and the recent implementation of policies to intensify the use of land and water resources, the transhumant pastoral systems in the Chinese-Mongolian Altay-Dzungarian region are rapidly changing, leading to modifications of herd size, herd composition and spatial distribution of livestock grazing. This may have major consequences for the supply and quality of rangeland biomass. Despite similar topographic settings, the socio-political framework for Chinese and Mongolian pastoralists differs ...
Evaluation of breeding strategies for polledness in dairy cattle using a newly developed simulation framework for quantitative and Mendelian traits
Background: Intensified selection of polled individuals has recently gained importance in predominantly horned dairy cattle breeds as an alternative to routine dehorning. The status quo of the current polled breeding pool of genetically-closely related artificial insemination sires with lower breeding values for performance traits raises questions regarding the effects of intensified selection based on this founder pool. Methods: We developed a stochastic simulation framework that combines the stochastic simulation ...
The relevance of herders’ local ecological knowledge on coping with livestock losses during harsh winters in western Mongolia
In many regions of the world, traditional and local ecological knowledge is still important today for coping with environmental challenges. This study explored the relevance of such knowledge for predicting and coping with harsh winter conditions (dzud) in a remote area of western Mongolia, where government support to disaster-affected herders is restricted by weak infrastructure. Structured face-to-face interviews were held in 50 households (HHs), addressing aspects of livestock possession and management as well as ...
Assessment of genetic diversity in local breeds
The present study aimed at assessing genetic diversity in selected local livestock breeds in Northern Germany, and furthermore, examining some of the indices used in describing diversity in populations. The study begun with an assessment of genetic diversity in the German Angler (RVA) and Red-and-white dual-purpose (RDN) cattle breeds. Analyses of the RVA and RDN pedigrees, consisting of 93,078 and 184,358 records, respectively, revealed a number of Red Holstein (RH) sires that were influential in these breeds. Even ...

Ökologische Mutterkuhhaltung in Deutschland
(Bio Austria, 2004)
Die Untersuchung bestand darin, Kenndaten zur ökologischen Mutterkuhhaltung in Deutschland zu erfassen. In einem Forschungsprojekt im Rahmen des Bundesprogramms ökologischer Landbau (Förderung durch die BLE, Bonn; vgl. HÖRNING et al. 2004) wurden Fragebögen von 388 Bio-Betrieben mit Mutterkuhhaltung ausgewertet und darüber hinaus 27 Betriebe aufgesucht zur Erhebung genauerer Daten.
Ermittlung geeigneter Methoden zur Differenzierung und Qualitätsbeurteilung unterschiedlicher Milchqualitäten aus verschiedenen on-farm-Experimenten
Zusammenfassung: Ziel der Arbeit war ein Methodenvergleich zur Beurteilung der Milchqualität unterschiedlicher Herkünfte. Am Beispiel von Milchproben aus unterschiedlicher Fütterung sowie an Milchproben von enthornten bzw. horntragenden Kühen wurde geprüft, welche der angewendeten Methoden geeignet ist, die Vergleichsproben zu unterscheiden (Differenzierungsfähigkeit der Methoden) und inwieweit eine Qualitätsbeurteilung möglich ist (hinsichtlich Milchleistung, Fett-, Eiweiß-, Lactose- (=F,E,L), Harnstoff-gehalt ...
Prevalence of intestinal parasites in small ruminants and their senstivity to treatments with ethnobotanical remedies in Cholistan, Pakistan
Livestock production contributes substantially to the livelihoods of poor rural farmers in Pakistan; strengthening pastoral communities plays an imperative role in the country’s thrive for poverty alleviation. Intestinal helminths constitute a major threat for pastoral livestock keepers in the whole country because chronic infestation leads to distinct losses in livestock productivity, particularly the growth of young animals. Synthetic anthelmintics have long been considered the only effective way of controlling ...
Human and Raptor Interactions in the Context of a Nomadic Society
(Kassel University Press, 2015)
This research project focuses on contemporary eagle-taming falconry practice of the Altaic Kazakhs animal herding society in Bayan Ulgii Province in Western Mongolia. It aims to contributing both theoretical and empirical criteria for cultural preservation of Asian falconry. This cultural as well as environmental discourse is illustrated with concentrated field research framed by ecological anthropology and ethno-ornithology from the viewpoint of “Human-Animal Interaction (HAI)” and “Human-Animal Behavior ...
Interrelatedness of grazing livestock with vegetation parameters and farmers’ livelihoods in the Mahafaly region, southwestern Madagascar
The study aims to get deeper insight into the highly extensive system of animal husbandry in the Mahafaly region of southwestern Madagascar. It tries to understand the major drivers for pastoral dynamics, land and resource use along a gradient in altitude and vegetation to consider the area’s high spatial and temporal heterogeneity. The study also analyzes the reproductive performance of local livestock as well as the owners’ culling strategies to determine herd dynamics, opportunities for economic growth, and future ...
