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 (HAB)”.

Analyse von unerwünschten Arzneimittelwirkungen antibiotikahaltiger Euterinjektoren von Mastitiden bei Kühen der Rasse Holstein- Friesian unter Berücksichtigung von Leistungsniveau, Genetik und Produktionsbedingungen
(2015-08-04)
Das Ziel der vorliegenden Arbeit bestand darin, detailliert Wechselwirkungen zwischen dem binären Gesundheitsmerkmal klinischer Mastitis auf der einen und Produktionsmerkmalen (z. B. Milch-kg) und funktionalen Merkmalen (z.B. somatischer Zellgehalt) auf der anderen Seite unter simultaner Berücksichtigung von Umwelt und genetisch bedingten Einflussgrößen auf phänotypischer und genetischer Ebene abzubilden. Die Studie fokussierte auf innovative Aspekte der genetisch-statistischen Modellierung bzgl. der Anwendung von ...

Heat stress response for physiological traits in dairy and dual purpose cattle populations on phenotypic and genetic scales
(2016-02-23)
The main objective of this thesis was to determine the potential impact of heat stress (HS) on physiological traits of lactating cows and semen quality of bulls kept in a temperate climate. The thesis is comprised of three studies. An innovative statistical modeling aspect common to all three studies was the application of random regression methodology (RRM) to study the phenotypic and genetic trajectory of traits in dependency of a continuous temperature humidity index (THI).
In the first study, semen quality and ...

Herd management and livestock productivity in the Altai region of Western Mongolia
(2016-08-17)
This thesis analyses the influence of qualitative and quantitative herbage production on seasonal rangelands, and of herd and pasture use strategies on feed intake, body mass development and reproductive performance of sheep and goats in the Altai mountain region of Bulgan county (soum) in Khovd province (aimag). This westernmost county of Mongolia is characterized by a very poor road network and thus very difficult access to regional and national markets. The thesis explores in this localized context the current ...

Effects of mild water restriction on digestion and nitrogen metabolism in a desert adapted goat breed
(2017-04-26)
Water is the main challenge facing animal husbandry in arid and semi-arid regions of the globe. These areas are characterized by a long dry season lasting between 6 and 8 months. At certain times during the long dry period, water can be so scarce that animals may face severe water shortages. Many studies have been conducted to highlight how ruminants cope during these times of severe water deprivation. Yet, livestock are much more often exposed to mild water shortages for several months in a year. Only a few studies ...
