摘要: Chedid, M., Jaber, L. S., Giger-Reverdin, Duvaux-Ponter, C. and Hamadeh, S. K. 2014. Review: Water stress in sheep raised under arid conditions. Can. J. Anim. Sci. 94: 243–257. Sheep breeds which are indigenous to semi-arid regions known for their ability adapt rustic environments, climatic variations as well shortages resources. scarcity, often combined with heat stress, is a common challenge facing these animals, causing physiological perturbations affecting the animal's productivity. This review reports effect of different forms water on indicators, blood parameters, thermoregulation immunological status sheep. Although breed may be significant, following generally observed responses: drop feed intake weight loss, increase evaporative cooling through panting, production small volume highly concentrated urine, haemoconcentration, high osmolality, immunosuppression.
