Are they different from other boluses?

Yes. Bimeda revolutionary boluses are completely unique

Through releasing sacrificial copper in the rumen, Cosecure is the only bolus designed to prevent and treat Thiomolybdate Toxicity before it occurs. As Thiomolybdate (MoS4) will first deplete copper in the rumen and, if there is not adequate copper there, bind to copper in the blood stream, it is vital that the bolus copper becomes active in the rumen. This is where Cosecure boluses are active. stomach

Some capsules deliver copper in the form of copper oxide. However copper oxide requires a low pH to become active. As the normal range of rumen pH is higher, between pH 5.5 and 6.5, it is chemically impossible for copper oxide to become active here. Copper oxide only becomes active in the abomasum (which has a pH range of 2 to 4), where it may simply be absorbed into the body and cannot stop the thiomolybdate uptake into the blood.

Cosecure is the only true dissolving bolus, and dissolves at a slow but constant rate.
