摘要： Drinking water quality is an important factor on dairy cows' health and production performance.Drinking water systems in large-scale dairy farms are difficult and inefficient to clean,and the pipelines and drinking troughs are easily contaminated by biofilm coverage to affect cows' health.This study investigated the effect of slightly acidic electrolyzed water(SAEW)as a disinfectant on drinking water quality of the drinking water system,to provide a method for designing an efficient,low-cost and healthy drinking water system for large-scale dairy farms.Further,disinfection of SAEW with an available chlorine concentration(ACC)of 30 mg L-1 for 12 min can kill 90.4％of microorganism in drinking water.After cleaning the drinking water system using SAEW with 30 mg L-1 ACC,the residual chlorine concentration of drinking water was maintained above 0.05 mg L-1 for 2 h and no residual chlorine remained after 6 h.The working time interval for cleaning the drinking water system with SAEW was 48 h according to turbidity.In dairy farms,dairy performance and the average milk yield per day can be promoted and increased by 9.3％after SAEW cleaning.
