The electrolyzed water is a type of water with biocidal properties, fungicidal and sporicidal. Its effectiveness is caused by its activation which gives it a high oxidation capacity. Therefore, electrolyzed water becomes a very effective breaker of cell membrane of microorganisms. Although during its activation, hypochlorous acid is released, it is instantly stabilised, which guarantees the safety in handling and respect for the environment. The aim of this study was to determine the effect of electrolyzed water as drinking water on the presence of bacteria in the water consumed by cows and the microbiological quality of milk produced. Water samples collected from drinking electrolyzed water showed negative results for contamination by aerobic, total coliforms, E. coli and faecal streptococci. Data showed a significant decrease of somatic cell count, total bacteriology and coagulase positive count in milk from cows that had drunk electrolyzed water.

Electrolyzed water is a type of water produced by the electrolyses of sodium chloride saturated water. Its use in animal production is recent. Yet there is little literature on the subject, although in broilers (Northcutt et al, 2007) supplied as drinking water for 16 hours before slaughter reduced significantly bacterial spread in the inner cavity of the channel. In Arabian horses it has improved their performance during competition, and even in piglets, the results provided by farmers who used it indicate a 80% less medication costs and a 70% reduction in mortality. Moreover, there was an increment of weight of 450 grams during the four weeks. The aim of this pilot study was to examine the effect of electrolyzed water intake on blood acid-base balance of dairy cows of different ages and times of their lactation curve. In order to do this, it was used the portable clinical analyzer I-STAT which uses disposable cartridges to determine blood pH and the following blood gases: partial pressure of carbon dioxide, bicarbonate, standard base excess, partial oxygen pressure, oxygen saturation and total carbon dioxide. The results showed that the electrolyzed water ingestion caused a significant increase in all parameters examined except for pH and partial pressure of carbon dioxide in the blood.

El agua tal como se encuentra en sus fuentes de abastecimiento, posee ciertas caracteristicas propias, que son el olor, sabor, color, sustancias quimicas disueltas, y microorganismos presentes en ella. Estas caracteristicas deberan ser modificadas con el proposito de hacerla apta para el consumo humano. Existen en la actualidad diversos tratamientos para la potabilizacion del agua, que van desde los mas antiguos y precarios, como la sedimentacion, hasta los mas modernos y complejos, como la osmosis inversa. El proposito de este trabajo es ofrecer una basica revision de todos los sistemas de potabilizacion disponibles en la actualidad.
