Potassium problem

MILK fever, retained afterbirths and slow calving have become more prevalent in spring-calving herds.

These problems can occur despite good management and feeding quality pre-calver minerals.

Silage analyses suggest that high potassium (K) may be the cause. This may be due to increased usage of slurry. The feeding of Kestrel salts, such as DC100, for three or four days before calving, is a solution.
