Limitation of water intake reduces animal performance quicker and more dramatically than any other nutrient deficiency (Boyles). Water constitutes approximately 60% – 70% of an animal’s live weight and consuming water is more important than consuming food (Faries, Sweeten & Reagor, 1997). Domesticated animals can live about 60 days without food but only about 7 days without water. Livestock should be given all the water they can drink because animals that do not drink enough water may suffer stress or dehydration.
Signs of dehydration or lack of water are tightening of the skin, loss of weight and drying of mucous membranes and eyes. Stress accompanying lack of water intake may need special considerations. Newly arrived animals may refuse water at first due to differences in palatability. One should allow them to become accustomed to a new water supply by mixing water from old and new sources. If this is not possible, then intake should be monitored to be sure no signs of dehydration occur until animals show adjustment to the new water source.
Water requirements are influenced by physiological and environmental conditions Continue reading Water Effects on Livestock Performance
