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.
