ABSTRACT
Domestic animals are exposed to saline stress in many instances such as when grazing halophytes or when the saline water from underground wells is the only available drinking water. The ability of ruminants to withstand this type of stress is affected by numerous factors (Squires, this volume). The age and the physiological status are critical factors, where young and productive animals are more sensitive. The presence of other types of stress such as heat and feed shortage will augment the effect of saline load. In other words, salinity tolerance of animals could vary with environmental conditions, type of feed, or physiological stages (Anon 1969).
