Abstract: The most difficult condition to treat in the dairy animal production cycle is milk fever, which occurs during the transition phase due to an imbalance in blood calcium (Ca) levels. In order to maintain a plasma Ca concentration, parathyroid hormone, calcitriol, and calcitonin are closely regulated to keep blood calcium levels within a restricted range. Dairy cows during the end of gestation need an adequate amount of calcium for maintenance, late-stage foetal growth, anticipated endogenous loss, and colostrum development. Ca is therefore also crucial for milk production in high-yield dairy cows at the beginning of lactation. Postpartum production and health can suffer from a delay in endocrine signalling or a failure to respond to restoring the circulating Ca. Milk fever can be controlled by a variety of principles and factors, such as feeding low-calcium rations just two weeks before calving, supplementing with vitamin D products during the transition period, feeding postpartum animals acidifying rations with negative dietary cation anoin difference (DCAD), and supplementing with ionic salt. Numerous studies have demonstrated the value of changing an animal's diet to reduce milk fever in dairy animals. The two most beneficial techniques among them are giving a diet that has a negative DCAD value in the same and reducing the amount of dietary calcium in transitory animal feed.
