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 ...

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 ...

Evaluation of breeding strategies for polledness in dairy cattle using a newly developed simulation framework for quantitative and Mendelian traits
(2016-06-29)
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 ...

Metabolic disorders in the transition period indicate that the dairy cows' ability to adapt is overstressed
(2015)
Metabolic disorders are a key problem in the transition period of dairy cows and often appear before the onset of further health problems. They mainly derive from difficulties the animals have in adapting to changes and disturbances occurring both outside and inside the organisms and due to varying gaps between nutrient supply and demand. Adaptation is a functional and target-oriented process involving the whole organism and thus cannot be narrowed down to single factors. Most problems which challenge the organisms ...

Phenotypic diversity, major genes and production potential of local chickens and guinea fowl in Tamale, northern Ghana
(2017-06-26)
Objective:
Our study provides information on phenotypes of local chickens and guinea fowl and their body measures as well as on major genes in local chickens in northern Ghana.
Methods:
Qualitative and morphometric traits were recorded on 788 local chickens and 394 guinea fowl in urban households in Tamale, Ghana.
Results:
The results showed considerable variation of color traits and numerous major genes in local chickens, while color variations and related genotypes in guinea fowl were limited. In local chickens, ...

The relevance of herders’ local ecological knowledge on coping with livestock losses during harsh winters in western Mongolia
(2018-01-29)
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 ...

Untersuchungen zur Tiergerechtheit in ökologisch wirtschaftenden Betrieben mit Legehennenhaltung
(Bio Austria, 2004)
Von 2002 bis 2004 wurde im Rahmen des Bundesprogramms Ökologischer Landbau eine Status Quo Analyse zur ökologischen Geflügelhaltung mit dem Titel „Ökologische Geflügelproduktion - Struktur, Entwicklung, Probleme, politischer Handlungsbedarf“ durchgeführt. Gesamtziel des Vorhabens war, detaillierte und aktuelle Informationen aus den Bereichen Tiergerechtheit inklusive Haltungssysteme und –bedingungen, Tiergesundheit und Wirtschaftlichkeit anhand einer repräsentativen Stichprobe zu erhalten und politischen Handlungsbedarf ...

Tiergerechtheit auf ökologischen Milchviehbetrieben
(Bio Austria, 2004)
Ziel des vorliegenden Forschungsvorhabens war, nähere Daten über die Tiergerechtheit in der Ökologischen Milchviehhaltung zu gewinnen. Die hier vorgestellten Ergebnisse sind Teil eines Forschungsvorhabens mit dem Titel „Ökologische Milch- und Rindfleischproduktion“, welches im Rahmen des Bundesprogramms Ökologischer Landbau durchgeführt wurde, gefördert durch die Bundesanstalt für Landwirtschaft und Ernährung (BLE), Bonn (HÖRNING et al. 2004). Dabei wurde ein zweistufiges Verfahren gewählt.
