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 ...

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 ...

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 ...
