£146 – milk fever price
MILK fever costs £146 a case according to the latest Kingshay Farming Trust report. The calculation is based on vet expenses, milk loss in the next lactation, and occasional deaths.
Results of a 45,500 cow survey revealed an average incidence of milk fever of 8%, with a range from no cases to over 30%.
However, incidence was below average in most surveyed herds which fed a magnesium supplement, it says.
The report claims that a combination of management, feeding and herd factors can aid prevention.
