Allsure Calf of intra-ruminal, leaching boluses use unique and proven leaching technology to provide slow release supplementation of the 4 essential trace elements at known and optimum levels for approximately 6 months with a single application. The boluses are easily given to ruminant animals using a specially designed Animax applicator. The bolus enters the animal’s rumen/reticulum and lodges there and the trace elements leach out from the bolus at a known and safe rate. Spent boluses eventually become enlarged and are shed naturally.

Copper oxide rods are released in the reticulo-rumen passing slowing through the ruminant stomachs for a period of 2 to 3 months.Exposure to abomasal acidity causes slow particle solution, enabling partial absorption to take place. The copper stored in the liver then acts as a depot from which copper is slowly released to maintain normal concentrations in the blood during periods when the animal may be receiving an inadequate copper intake. The recommended dosage should maintain adequate copper levels for the whole grazing season unless more frequent dosing is required on veterinary advice.
