Bolutech Flash Cow Calcium Bolus

  • On average, milk fever effects 5% of dairy cows but more than 50% of multiparous cows have hypocalcemia during calving.

    This metabolic disorder is most often invisible and leads to a drop in muscle tone and immunity. This results in an increase in the duration of calving and delivery, with increased sensitivity to metritis. Another direct consequence is the loss of apetite and watering. This increases the risk of displaced abomasum and encourages ketosis.

    The combination of the costs linked to these disorders and the drop in performance results in a significant economic loss.
