Abstract: Electrolyzed water is a new type disinfectant agent which has been recognized as instantaneous, universally applicable, effective, cheapness, safe, without chemical residues and no pollutions. Based on the electrolysis form and degrees, it can be divided into five types, and every types used in different areas. It was widely used in food processing industry. In recent years, researchers start to use it in the disinfection of livestock production, and achieved sound effects. Use alkaline water as the animal drinking water can promote animal health. This article has discussed the electrolyzed water's formation mechanism, physicochemical properties, and its mechanism of function. The prospect of the electrolyzed water applied in livestock production is also reviewed.

Key words: livestock production; electrolyzed water; disinfection
