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. 2g capsule = Use with lambs only when copper supplementation is required. Prolonged release of copper for 180 days. Lambs over 10 kg and over 5 weeks old: 1 capsule 4g capsule = Use with sheep and calves only when copper supplementation is required. Prolonged release of copper for 180 days. Application guidelines: Adult sheep over 50 kg: 1 capsule. Ruminant calves 75 – 100 kg and over 2 months old: 2 capsules 35g Bolus = Use with cattle only when copper supplementation is required. Prolonged release of copper for 180 days. Application guidelines: Cattle over 200 kg: 1 bolus Cattle over 501 kg: 2 boluses
