博威钙预防奶牛产后低血钙的效果观察

摘要

高产奶牛产后亚临床低血钙的发病率40.74%,凭借自身钙调节能力无法在产后24h将血液离子钙恢复正常水平.博威钙对奶牛血液有轻微的酸化作用,可增强钙动员调节机制,奶牛在产后0h、12h两次投服博威钙,能明显提高血液中离子钙水平,对奶牛产后低血钙有很好的预防作用.%The prevalence of subclinical hypocalcemia in the transition cow is 40.74％. The cow' s body cannot re-balance the loss of calcium in 24h after parturition by themselves. Bovikalc led to a slight acidification of the cow' s blood and enhanced the mobilisation of the cow's own calcium reserves. It can be used twice after calving for cows susceptible to acute or sub-clinical milk fever.
