Abstract: Milk fever is a nutritional metabolic disease caused by the decrease of blood calcium level at cow’s lactation stage, which has a great impact on the health and production performance. It increases the risk of reproductive inflammation, reproductive disorders and endocrine, digestion and other diseases in cows, causing great losses to the farming industry. There are many factors that affect milk fever in cows, including breed, age, physical condition scores, previous case of milk fever and other factors. Besides, the influence factors of feeding management containing previous lactation length, dry period length, calving interval and the control of cow feed nutrition level, and external factors such as climate and environment, also affect the incidence rate of milk fever. These factors often intertwined with each other, increasing the difficulty of prevention and treatment of milk fever in dairy cows. This paper summarized the pathogenesis of milk fever in cows, analyzed the mechanism of influence of various factors on milk fever in cows, and introduced several methods to prevent and control milk fever in cows. It mainly included the management of dairy farming environment, the control of the interval and lactation of cows, and the regulation of feed nutrition levels at different stages of cows, so as to provide a theoretical basis for reducing milk fever in cows.
