Rumbul Magnesium Bullets (pack of 20).
A sustained release bolus containing an alloy of magnesium, copper and aluminium. Licenced to aid the prevention of hypomagnesaemia in cows and ewes grazing rapidly growing Spring grass. Rumbul helps farmers manage the magnesium status of their herd or flock over high risk periods.
Benefits
•Effective prevention of grass staggers in dairy cows, ewes and suckler calves
•Certain supply of magnesium during high risk period
•Use pre-calving to help boost magnesium intake
Efficacy
Rumbul has been tested in several trials and the results have been published in peer reviewed scientific journals. Trial work has shown the following:
•Effective prevention of clinical hypomagnesaemia (grass staggers) in cows, ewes and calves
•Many farmers now give cows Rumbul Magnesium Bullets towards the end of the dry period to help mobilise calcium at calving.
Administration
Cattle - 2 bullets per head
Ewes - 1 bullet per head
Calves - 2 bullets per head
It is vital that bullets are dosed at least 2-3 days before the onset of the period of risk (e.g. day of turn out). Rumbul bullets take a day or two before starting to release magnesium.
The active life of Rumbul cattle is 28 days
The active life of Rumbul sheep and calf is 21 days
