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, ...

Emerging Development Pathways of Urban Livestock Production in Rapidly Growing West Africa Cities
(2016-11-19)
In this study, we try to capture the degree of specialization or integration, and of intensification or extensification, of (peri-) urban livestock production, along with the factors that influence such decisions and their impact on natural resource uses. A total of 181 and 187 structured questionnaires were completed in livestock-keeping households in Ouagadougou (Burkina Faso) and Tamale (Ghana). Categorical principal component and two-step cluster analysis were used to identify homogenous groups of livestock-keeping ...

Vereinbarkeit von muttergebundener Kälberaufzucht und automatischen Melksystemen
(2019-12)
Muttergebundene Kälberaufzucht stößt sowohl in der Öffentlichkeit als auch bei milchviehhaltenden (Öko-)Betrieben auf zunehmenden Zuspruch. Gleichzeitig steigt die Zahl der installierten AMS auf den Milchviehbetrieben. Diese Entwicklungen weisen darauf hin, dass in Zukunft mehr Betriebe die muttergebundene Kälberaufzucht mit den AMS kombinieren werden. Bei der Kombination besteht die Herausforderung darin, den Kühen das individuelle Melken im AMS zu gewähren und gleichzeitig die Kälber an diesen Kühen aufzuziehen. ...

Spatio-temporal patterns of herbage availability and livestock movements: A cross-border analysis in the Chinese-Mongolian Altay
(Springer, 2016-07-04)
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 ...

Evolution of Rural Livelihood Strategies in a Remote Sino-Mongolian Border Area: A Cross-Country Analysis
(2018-03-29)
Ecologically sound natural resources management is still the backbone of rural livelihoods in many regions of the world. The Altai-Dzungarian region between China and Mongolia constitutes an ideal site to study how political, economic, infrastructural, and cultural differences affect rural livelihoods. Structured semi-quantitative interviews were conducted with 483 households on both sides to characterise their current livelihood strategies and assess the importance of the various activities for the households’ current ...

Participatory Mapping as an Approach to Identify Grazing Pressure in the Altay Mountains, Mongolia
(2018-06-11)
Sustainable rangeland management is crucial for maintaining forage resources in pastoral systems, globally. However, pastoral regions are often remote and therefore data poor when it comes to resource monitoring. We tested participatory mapping as a means to rapidly assess rangeland use to identify areas with high grazing pressure. Participatory geographic information system data and herbaceous biomass production data were collected and georeferenced to establish a grazing pressure index for a summer pasture in the ...

Untersuchung der Eignung alternativer Putenherkünfte für ein ökologisches Haltungssystem
(2019-03)
Dissertation Anna Olschewsky 2019: Untersuchung der Eignung alternativer Putenherkünfte für ein ökologisches Haltungssystem
Obwohl der Anteil ökologischer Putenhaltung in Deutschland mit weniger als 2 % vergleichsweise gering ist, erfährt die Branche insbesondere wegen des Einsatzes schnell wachsender konventioneller Linien und teilweise hohen Prävalenzen verschiedener leistungs- und hal-tungsbedingter Krankheiten Aufmerksamkeit. Zum Umfang dieser Probleme bei alternativen langsamer wachsenden Putenherkünften ...

Determinants of resource use and use efficiency in urban and peri-urban dairy, beef cattle and pig production units in Ouagadougou, Burkina Faso (West Africa)
(2019)
The (peri-) urban demand for food of animal origin is increasing in sub-Saharan Africa as a result of the rapidly growing population and urbanisation. Livestock production in the vicinity of West African cities is well established but currently undergoes changes triggered by key transforming factors such as access to resources, production management related to famers' knowledge or know-how, increasing demand for livestock and/or animal products, policies and the legal framework in which livestock production systems ...
