Résumé
Arid and semi-arid regions have limited arable land and water resources. As a result, production of grain and forage is often insufficient to fulfil the requirements of lactating animals. The absence of grassland has led to the dominance of grains based diets imported from overseas. This has an ecological impact due to the emissions of greenhouse gases (GHGs) from land change activities. In addition, the prices of these grains are increasing. Therefore, the objectives of this thesis were to evaluate the nutritional and ecological aspects of the dairy farming systems and feeding strategies dominant under semi-arid environmental conditions in Jordan, and to evaluate how dairy production systems will respond to future changes in feed items and feed prices.
