围产期母牛在产犊时经历从非泌乳期到泌乳期的转变。动物在维持钙稳态方面面临着巨大的挑战。那些失败的人可能会患上产奶热，这是一种危及奶牛生命的临床疾病，并使动物容易患上各种其他疾病。回顾了低钙血症发生率监测指南和乳热治疗方法。讨论了引起产奶热的生理因素和预防产奶热的策略，重点讨论了饮食阴阳离子差异对组织对甲状旁腺激素敏感性的影响。产奶热的另一个主要危险因素是低镁血症，当动物喂食镁量不足或饮食中存在某些阻碍镁充分吸收的因素时，就会出现低镁血症。中度低镁血症会损害奶牛维持钙稳态的能力，并发生低钙血症。由爱思唯尔有限公司出版
The periparturient cow undergoes a transition from non-lactating to lactating at calving. The animal is tremendously challenged to maintain calcium homeostasis. Those that fail can develop milk fever, a clinical disorder that is life threatening to the cow and predisposes the animal to a variety of other disorders. Guidelines for monitoring the incidence of hypocalcemia and methods for treating milk fever are reviewed. The physiological factors that cause milk fever and strategies for prevention of milk fever are discussed, focusing on the effects diet cation-anion difference can have on tissue sensitivity to parathyroid hormone. Another major risk factor for milk fever is hypomagnesemia, which is observed when animals are fed inadequate amounts of magnesium, or some factor is present in the diet that prevents adequate absorption of magnesium. Moderate hypomagnesemia impairs the ability of the cow to maintain calcium homeostasis and hypocalcemia occurs. Published by Elsevier Ltd.
