摘　　要：荷斯坦牛产前7d亚临床低血钙发病率为1.25%,头胎牛产后24h内亚临床低血钙发病率为2.5%,无需补钙处理;经产牛产后24h内亚临床低血钙发病率为75%,需产后立即口服补钙。经产牛产后乳维宝自饮率为71.25%,可大大降低保健工作量,并能在产后12h内解除亚临床低血钙风险,推荐用于产房人员不足及规模化牛场集中产犊情况下的经产牛产后瘫痪的预防。The morbidity of subclinical hypocalcemia is 1.25% for dairy cows at 7 days prepartum. Only 2.5% of the heifers appear subclinical hypocalcemia after calving, so they don＇t need calcium supplements. Considering the 75% incidence of subclinical hypocalcemia for multipara cow within 24h postpartum, they need oral calcium supplements immediately after calving. The self-drinking rate of Reviva is 71.25% for multipara cows postpartum. Reviva is effective in preventing milk fever and recommended for multipara cows.
