Over 40 years’ experience in UK animal nutrition and bolus manufacturing expertise has gone into producing EnduraBol®, which is manufactured using original, patented technology.
Single point of erosion
EnduraBol® is a single-construction bolus that releases micronutrients with a single point of erosion from a constant surface area.
A candle burns from the top to the bottom, but no matter how long or short a candle is, the burning area is always the same circumference. works in a similar way to deliver a consistent and sustained daily supply of six trace elements and three vitamins, for up to eight months.
During manufacture the bolus is dipped in a crystic resin, dried and dipped again for an impenetrable twin-coated finish. It is also dipped in wax at the top to ensure it is sealed to avoid oxidisation, so that it can be fully optimised when entering the rumen.
As the bolus starts to erode in the reticulum, the top of the resin coating chips away in small amounts. This is vital to ensure a sustained release of trace elements and vitamins during the bolus lifecycle.
Beneath the resin coating, the micronutrients are held in a matrix structure, allowing a slow and consistent release. An inert, dissolvable end-weight ensures the bolus remains in place until all nutrients are absorbed.
When the bottom of the bolus is finally reached, the end-weight is exposed, which dissolves leaving no residue.
