摘　　要：奶牛产后低血钙是规模化牧场常见的营养代谢性疾病之一,因其造成的牛只淘汰、生产性能下降和并发的多种疾病,每年给牧场带来巨大的经济损失。阴离子盐日粮是一种用于预防奶牛产后低血钙的营养调控技术,目前在国内部分牧场有所应用。阴离子盐日粮的使用对管理人员的技术要求较高,良好使用可有效降低产后低血钙的发病风险,使用不当则有可能诱发产后低血钙,甚至损害奶牛健康。本文从万头牧场的视角出发,总结了一线生产中阴离子盐日粮使用的经验方法,旨在为同行牧场提供一定的参考。Postpartum hypocalcemia in dairy cows is one of the common nutritional and metabolic diseases in largescale ranches.Due to the elimination of cows,decreased production performance,and multiple concurrent diseases,it brings huge economic losses to the ranch every year.Anionic salt diet is a nutritional regulation technique used to prevent postpartum hypocalcemia,which is currently applied in some domestic pastures.The use of anionic salt diets requires high technical requirements from management personnel.Good use can effectively reduce the risk of postpartum hypocalcemia,while improper use may induce postpartum hypocalcemia and even damage the health of cows.This article summarizes the experience and lessons learned from the use of anionic salt diets in frontline production from the perspective of Wantou Farm,aiming to provide some reference for peer farms.
