Norbrook Norophos+ Bolus

Bolus for dairy cows to reduce the risk of phosphorus deficiency after calving. High content levels of fast-available phosphorus (37g per bolus) and 15g calcium per bolus. Can be given alongside Calcitrace D3 to provide high levels of both calcium and phosphorus. Administer one bolus at the time of calving and, if necessary, a second 12 hours later.
