Current knowledge of water quality and safety for livestock.
Basic laboratory evaluation of water quality for livestock should include measurement of TDS, sulfate, nitrate-nitrite, and coliform bacteria. Supplementary water tests may include pH, sodium, iron, magnesium, chloride, calcium, potassium, manganese, and contaminants specific to the situation. Using the best-quality drinking water available contributes to the optimal production of livestock. Restricted quantity of drinking water or drinking water containing excessive levels of nitrate, TDS, sulfate, and other constituents can affect growth and production of all classes of animals. Drinking-water quality and availability should be evaluated as a cause of poor performance or nonspecific disease conditions in livestock. It is important that attempts to evaluate water quality include obtaining a thorough history, making astute observations, and asking intelligent questions. A thorough laboratory examination of animal specimens and water samples should be evaluated in view of existing standards for livestock drinking-water quality.
