1970's - 1980's
Dr. Steward Telfer (Animal Nutrition, University of Leeds) explores delivering trace elements to the reticulum of ruminants using soluble glass.
Research Team Forms
Dr Telfer, George Zervas (PhD student), and Peter Knott (Leeds Ceramics Dept) set out to develop a soluble glass bolus containing essential trace elements.
Research Team Forms
Breakthrough
Combination of glass and nutrition expertise → Patent-protected soluble glass bolus with constant, controlled trace element release for months.
Industry Partnership
Patent attracts Dr. Brian Algar at Pilkington Glass → leads to joint University-Pilkington project for further glass technology development.
Industry Partnership
Commercialisation Under Bimeda
In October 2013, Bimeda Animal Health acquired Telsol who previously launched Cosecure boluses to the UK market.
Today
Cosecure boluses are used worldwide and remain the only soluble glass trace element bolus delivering rumen available ionic copper to tackle both forms of copper deficiency.
Today
What is the difference between rumen-available copper and copper oxide?
Feature | Cosecure Soluble Glass Boluses | Other Nutritional Capsules/Boluses |
|---|---|---|
Form of Copper | Ionic Copper | Copper oxide |
Activation pH | Active at rumen pH (5.5-6.5) | Active only at low pH |
Effectiveness in the Rumen | Yes - releases rumen-available, sacrificial copper | No - copper oxide is not active in rumen conditions |
Trace-Element Availability | Provides rumen-available copper, essential for effective supplementation | Cannot provide rumen-available copper due to pH mismatch |
Key Advantage | Only bolus delivering ionic copper in the rumen to prevent thiomolybdate toxicity | Limited activity, copper becomes available only in lower pH sections of the digestive tract |
FAQS
The critical difference between Cosecure and other nutritional supplements is that Cosecure supplies rumen-available elements.
The copper in our unique boluses is in the form of ionic copper, which is active in the same pH range as the rumen. This means that the minerals are highly available to the animals in the rumen.
Some boluses supply copper in the form of Copper Oxide. Copper Oxide is active at much lower pH levels, and requires exposure to abomasal acidity before release of the copper.
Copper Myths
Reality: Thiomolybdate (MoS4) binds to copper and makes it useless. However, this useless copper will still show up in blood tests.
