Rumbul Magnesium Bullets for Cattle and Sheep

Description 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.

Technology

Rumbul bullets are designed to lie in the reticulum and dissolve, by electrolytic action, in a uniform and even manner providing a continuous supply of magnesium.

Composition

When to use* Rumbul*

Dairy Suckler beef – Cow/Calf beef Sheep Dairy cows over 300kg Ewes over 30kg Calves over 50kg Spring turnout in dairy cows Spring turnout in post lambing ewes Spring turnout in suckler calves Dairy cows 2-3 weeks pre-calving

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

Always use the recommended Agrimin bolus applicator.
