Abstract
BACKGROUND AND AIM: Water is the most important nutrient for the production of healthy livestock. Water scarcity bottlenecks livestock production in arid and semi-arid regions, particularly during the dry season. This study aimed to assess water availability and quality for small ruminants, and to identify major challenges of meeting their water requirements in two major small ruminant production systems in Jordan.Entities:
