Calcium to fore in milk fever battle
COWS at high risk of milk fever can be given a new drench after calving to increase blood calcium levels, claims UK supplier Louvic.
It says that huge amounts of calcium are needed in early lactation. Cows that suffer from milk fever can lose 10% of their potential production for that year, it adds. But there is also concern that cows may be sub-clinically affected by milk fever.
The Cal Drench Plus is a source of calcium and energy that is most needed after calving, especially by those cows that have high body condition scores or by high yielding and older cows.
It is said to be easy to dose cows using the drenching gun. It costs £3 for a 200ml dose (£15 a litre bottle) (01993-709795).
