Rumbul Magnesium Bullets are particularly recommended for adult dairy cattle and sheep when grazing rapidly growing grass in the spring when there is a well defined period of high risk. It is difficult to establish experimentally their effect at other times of year when clinical tetany may occur unexpectedly.

Consumption of more than small amounts of other feeds (e.g. hay, silage, concentrates) may, by altering the pattern of rumen fermentation, change the rate of release of magnesium from the bullets. Rumbul Magnesium Bullets may occasionally be regurgitated. This may happen very shortly after being administered if they have not been completely swallowed. The bullet may more readily reach the reticulum or base of the rumen if it is not given immediately after hay or silage has been given. Animals should be observed carefully for a few minutes after administration. Towards the end of their useful life (when the bullets become both shorter and of greatly reduced diameter) there is a small chance that regurgitation may occur. If it is noticed that an individual animal has regurgitated a bullet, treatment should be repeated.

Rumbul Magnesium Bullets do not necessarily restore blood magnesium concentration to accepted normal levels. In the vast majority of situations good control of hypomagnesaemic tetany is obtained. However, because of the varying complexity of factors involved in the condition as it occurs in different situations there may be a very small proportion of animals which do not respond to the treatment. Rumbul Magnesium Bullets cannot be expected to correct chronic hypomagnesaemia which may follow a long period of under-nutrition.

In areas where there is no known copper deficiency, no additional supplement of copper should be given to animals which have been administered Rumbul Bullets, for the active life of the bullets.
