Between dry-off, at around 60 days before calving, and one month after giving birth, cows are most at risk of infection and ketosis. During these Vital 90TM Days , their natural defence mechanisms are down and they are expending more energy than they are taking in. This leaves cows vulnerable to mastitis, retained placenta and metritis, as well as ketosis – putting the health and productivity of the individual and the herd at risk1-4.
