To prevent Grass Tetany (hypo-magnesemia) and death from low blood magnesium levels. Tetany typically occurs at times of stress that collide with rapidly growing green grass. Turn out in Spring and Weaning are the most common times to use opti-mag. Give 2 boluses to supply 6 g of rumen available magnesium 48 to 72 hours before the risk activity to supply magnesium for 4 to 6 weeks.
Only Use Norbrook’s gun to administer these and if cows are hungry for a few hours before it leads to less regurgitation.
Upto 80% of cows with Tetany are found dead so prevent it with 2 opti-mag Spring and especially Autumn.
