Effects of Different Feeding Regimes on the Digestibility and Faecal Excretion of Nitrogen, Soluble Carbohydrates and Fibre Fractions in Water Buffaloes kept under Subtropical Conditions
(2010-11-12)
In the course of the ‘Livestock Revolution’, extension and intensification of, among others, ruminant livestock production systems are current phenomena, with all their positive and negative side effects. Manure, one of the inevitable secondary products of livestock rearing, is a valuable source of plant nutrients and its skillful recycling to the soil-plant interface is essential for soil fertility, nutrient - and especially phosphorus - uses efficiency and the preservation or re-establishment of environmentally ...

Horizontal nutrient fluxes and production efficiencies in urban and peri-urban crop and livestock husbandry of Niamey, Niger
(2009-11-17)
Urban and peri-urban agriculture (UPA) increasingly supplies food and non-food values to the rapidly growing West African cities. However, little is known about the resource use efficiencies in West African small-scale UPA crop and livestock production systems, and about the benefits that urban producers and retailers obtain from the cultivation and sale of UPA products. To contribute to filling this gap of knowledge, the studies comprising this doctoral thesis determined nutrient use efficiencies in representative ...

Designing Breeding Programs For Improving Milk Yield Performance Of Indigenous Genous Dairy Cattle In Sudan
(2022)
The overall aim of the present study was to design appropriate breeding programs for the sustainable improvement of Butana cattle in Sudan. Four studies were conducted, beginning with a comprehensive review of literature on indigenous dairy cattle breeding strategies in sub-Saharan Africa with a focus on the factors that contribute to their success or failure. It showed that crossbreeding of indigenous breeds with exotic breeds has been widely used for genetic improvement, but it largely failed under low-input ...

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)”.

Dimensionierung und Gestaltung von Laufställen für behornte Milchkühe unter Berücksichtigung des Herdenmanagements
(2011-11-23)
Die Haltung von Milchkühen in einem Laufstall hat sich aus arbeitswirtschaftlichen und Kostengründen stark verbreitet. Im Biolandbau wird diese Entwicklung vor allem aufgrund der höheren Tiergerechtheit dieser Haltungsform forciert. Gleichzeitig werden die allermeisten Kühe für die Laufstallhaltung jedoch enthornt, unter anderem weil sich in den üblichen Ställen mit Normmassen und –konzepten Probleme mit Verletzungen unter den Tieren ergaben. Dabei sprechen die Richtlinien und Verordnungen für biologisch wirtschaftende ...

Ermittlung geeigneter Methoden zur Differenzierung und Qualitätsbeurteilung unterschiedlicher Milchqualitäten aus verschiedenen on-farm-Experimenten
(2011-12-14)
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 und ...

Effect of management strategies on the performance of ruminant livestock production systems and the safety of plant and animal products in the city of Sikasso, Mali
(kassel university press, 2012-05-02)
The regional population growth in West Africa, and especially its urban centers, will bring about new and critical challenges for urban development policy, especially in terms of ensuring food security and providing employment for the growing population. (Peri-) urban livestock and vegetable production systems, which can contribute significantly to these endeavours, are limited by various constraints, amongst them limited access to expensive production factors and their (in)efficient use. To achieve sustainable ...

Influence of quebracho tannin extract and activated charcoal on nutrient intake and digestibility, digesta passage, nitrogen balance, and quality of faecal excreta in goats
(kassel university press, 2015)
The current study investigated the possibilities of producing manure that meets the specific requirements of irrigated organic cropping systems under arid sub-tropical conditions.
Therefore, two trials with goats were conducted that investigated the impact of control diets on their digestibility and faecal concentration with the goal to lowerfaecal concentration levels and meet the requirements of irrigated organic cropping.
Feeding ruminants with condensed tannins (CT) will lower ruminal protein degradation, ...

Implementation of targettarget-orientated approaches in antibiotic and homeopathic treatment of acute bovine clinical mastitis in dairy practice
(2022-07)
Diese kumulative Dissertation hatte das übergeordnete Ziel Rahmenbedingungen (Voraussetzungen) für einen hohen Behandlungserfolg bei der antibiotischen und homöopathischen Mastitistherapie auf Milchviehbetrieben zu identifizieren sowie mögliche Optionen zur Erhöhung der Heilungsraten zu ermitteln. Darüber hinaus wurde die Steigerung des Behandlungserfolges unter der Maßgabe eines reduzierten Antibiotikaverbrauchs untersucht.

Evaluation of efficacy of homeopathic and antibiotic treatment in scientific research and practice with focus on bovine mastitis
(2024)
The use of homeopathy and antibiotics in treatment have the same goal: to cure a diseased individual. The first choice should be the most effective treatment and only a repeated treatment success will justify its use. If the chosen treatment is not effective, unnecessary suffering of diseased animals, spreading of disease or chronification of mastitis will be the result. Additionally, in case of antibiotic use, an ineffective use will select and promote the prevalence of multi-resistant bacteria in the environment, ...
