With the continuous improvement of people's material living standards, the demand for livestock and poultry products is also increasing. As an important part of animal husbandry,dairy industrialization is an important way for farmers and herdsmen to increase production and income. In the process of raising cows,the amount of milk production directly affects the economic benefits of farmers（households）. How to make dairy cows give full play to their lactation performance has always been a problem to be solved in the process of dairy farming. On the basis of expounding the production characteristics of high-yield dairy cows,this paper analyzed the key points of high-yield dairy farming technology from many angles, so as to provide a theoretical basis for dairy farms（households）to feed and manage correctly and give full play to the production performance of dairy cows.
