The antimicrobial activity of neutral electrolyzed water against germs and fungi from feedstuffs, eggshells and laying hen house

摘要

The work consisted in studying the sanitation effect of neutral anolyte(ANK) on pathogen agentsfrom poultry housing space, eggshells and feedstuffs, used to laying hens nutrition.It has used threesolutions of neutral anolyte in water: a) ANK solution with an active chlorine content of 8mg/l and12mg/l respectively, used as drinking water for laying hens; b) ANK solution with an active chlorinecontent of 8mg/l and 12mg/l respectively used for treatment the seven types of feedstuffs (maize, barley,maize gluten meal, rice, barley, soybean meal and canola meal), three mixed feeds, and five types ofeggshells, respectively. Treatments consisted in the immersion for 15min of each sample in ANKsolution; c) ANK solution with an active chlorine content of 36mg/l used for hen-house spacetreatmentby washing it for 15 min.The ANK solution with 36 mg/l active chlorine had a total bactericidal effecton the Total coliform, meantime the total number of germ from feedstuffs decreased with 14.29% untilto 97% against the control in case of 12 mg/l active chlorine. The experiment highlights the role ofactive chlorine on the microbiological load in the water, feedstuffs, diets, eggshells and hen-housespace. As the concentration of active chlorine is much higher as more significant is the bactericidaleffect of the ANK solution.
