In order to master the characteristics of water use in dairy farms systematically and comprehensively, and put forward the scientific and reasonable water-saving measures. By means of literature review and field research, the paper outlined the current situation of dairy farming at China and abroad, and systematically summarized the features, changing rules and influencing factors of water use in the link of dairy farming. The results showed that drinking water, clean water and cooling water were the main water structure of dairy farming at home and abroad. The scale of breeding, the proportion of lactating cows, the type of milking parlour and the climate features were the main factors affecting the characteristics of dairy water consumption, and the construction of multi-factor water consumption prediction model was a research hotspot. It was determined that drinking water, milking parlour water and spray water were the key water-saving links in dairy farming, and specific suggestions were presented for the follow-up water-saving research in dairy farming process, for providing technical support for pollution prevention and control in dairy farm.
