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, ...

Yield performance and weed control efficiency of organically managed silage maize double cropping systems
(2023)
Maize is among the three most important crops worldwide, while its multifunctional nature allows a diversified use. However, the traditional (silage) maize production often has negative side-effects related to the unprotected soil surface — e.g., erosion, weed pressure and related mechanical weed control. There are several alternative management systems to enhance the sustainability of (silage) maize production. However, the means and strength of influence are still unclear in some cases. Therefore, the current thesis ...

Management effects on soil microbial functions at a South-Indian rural-urban interface
(2023-06)
Urbanization leads to effects on many aspects of ecosystems and societies. Among the affected are agricultural systems and, specifically, soils. One of the most evident pathways of urbanization effects on agricultural soils is through an increased demand for agricultural commodities requiring agricultural intensification, hence, changes in management practices that alter soils.
In this context, the purpose of this study was to understand how the main agricultural management practices taking place in urbanizing ...

Organische Düngung und reduzierte Bodenbearbeitung als Steuerungsfaktoren für die C-, N-, P- und S-Speicherung von Mikroorganismen
(kassel university press, 2010-07-12)
In dieser Arbeit wurden zum einen die Auswirkungen mineralischer und organischer Düngung und zum anderen der Einfluss reduzierter Bodenbearbeitung (Kreiselegge) im Vergleich zum Einsatz des Wendepfluges auf die Nährstoffspeicherung der mikrobiellen Biomasse untersucht. Dabei wurde deutlich, dass sowohl organische Düngung als auch die reduzierte Bodenbearbeitung zu einer Erhöhung des organischen Kohlenstoffs (Corg), des Stickstoff-Gesamtgehalts (N) und des mikrobiellen Biomasse Kohlenstoffs (Cmik) und Stickstoffs ...

Matter flows and balances in urban vegetable gardens of Bobo Dioulasso, Burkina Faso (West Africa)
(kassel university press, 2012-07-30)
Many efforts are undertaken for sustaining urban agriculture in African cities. This study therefore investigated nutrient management practices in urban vegetable gardens of Bobo Dioulasso, Burkina Faso (West Africa). Nitrogen (N), phosphorus (P), potassium (K), and carbon (C) fluxes were quantified and nutrient balances calculated for three gardens representing the typical commercial gardening + field crops and livestock system (cGCL) and three gardens representing the commercial gardening + semi-commercial field ...
Dissertation
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.
Dissertation
Entwicklung eines innovativen Produktionsverfahrens für die Herstellung von Wurstwaren ohne Verwendung von Zusatzstoffen
(2023)
Das Ziel der vorliegenden wissenschaftlichen Untersuchungen ist die Entwicklung von Produktionsverfahren für Brüh- und Frischwurst ohne die Verwendung von Nitritpökelsalz und anderen Zusatzstoffen, die mittels Angaben von E-Nummern deklariert werden müssen. Am Beispiel von Bio-Lyoner in Dosen und Bio-Edelsalami wurden im Rahmen eines F&E-Vorhabens, welches unter Praxisbedingungen bei der Bäuerlichen Erzeugergemeinschaft Schwäbisch Hall (BESH) durchgeführt wurde, innovative Produktionsverfahren entwickelt und auf ihre ...

Plant growth, water quality, carbon and nutrient flows in rural-urban cropping systems of Bengaluru, India
(2024)
The global urban population is expected to reach 5.2 billion by 2030 and by mid-2023 approximately 4.6 billion out of more than 8 billion population were living in towns or cities. This represents approximately 57% of the total global population and is set to reach 60% by 2030. India’s urban population is expected to reach 607 million by 2030 and by mid-2030 40% of the total population will be living in urban areas. Growing urban population has multi-sectoral and dimensional implications in the rural, peri-urban, and ...
Dissertation
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, ...

Fostering sustainable consumption through communication: Consumers’ appreciation of biodiversity-friendly pasture-based cattle husbandry
(2024-01)
Considering dramatic environmental changes, there is an evident necessity of a transition to more sustainable animal production that caters to societal demand for ethical production and consumption. The slow but steady shift in consumer demand for animal-friendly, environmentally, and socially re-sponsible animal products has been well documented over the past years. The overarching goal of this dissertation is to provide insights regarding consumer perceptions, acceptance, preferences and com-munication of ...
