With the overall focus on driving rumen efficiency and utilisation
from forage, anything that contributes to maximising milk from forage should be seen as a positive development.
Outstanding handling and stability As well as performing at animal level, Selko IntelliBond trace minerals have been produced to ensure superior characteristics during feed manufacture. Patented Optisize Large Particle Technology helps ensure there

and allow significantly higher bioavailability but at a reduced cost compared to the organic sources.
Better fibre digestion An added benefit of supplying trace elements in a form which is not reactive in the rumen is optimised rumen performance. When inorganic trace elements like sulphates are fed and they ionise in the rumen, the resulting antimicrobial properties disrupt the fibre-digesting bacterial populations, leading to a reduction in fibre digestion and subsequent performance. Trials at Ohio State University have shown that replacing sulphate
trace elements with hydroxy trace elements had a positive effect on the digestibility of Neutral Detergent Fibre (NDF) in beef and dairy cattle (Figure 3).
are no detrimental effects to the stability and feed quality of premixes and finished feeds. The technology helps deliver a more uniform particle size for more predictable measuring and handling, while ensuring more even distribution throughout the feed. The non-hygroscopic property of the particles prevents absorption
of moisture from the atmosphere, so eliminating caking and clumping. It also reduces the negative interactions with moisture added during the compound manufacturing process, improving nutrient availability and stability. IntelliBond hydroxy trace minerals are the first new development
in trace mineral technologies for over 30 years, and backed by nearly 200 research trials, give a proven way to improve mineral bioavailability to improve animal performance while helping control feed costs for improved margins.
Technical mineral conference IntelliBond trace minerals were one of the subjects discussed when, Trouw Nutrition GB held a technical mineral conference on Tuesday 11th
June, bringing together leading academic scientists, researchers
and industry leaders to exchange and share their experiences on innovative and sustainable ways of improving long term animal productivity.
The agenda covered: • an update on mineral availability and requirements by Dr. Bill Weiss, from Ohio State University • Principles of animal zinc metabolism and consequences for experimental studies by Dr. Daniel Brugger, Chair of Animal Nutrition at Technische Universität Munich • Effect of trace mineral sources on digestive function by Dr. Jean-Baptiste Daniel, Trouw Nutrition Research • Introduction to IntelliBond by Kevin Perryman, Trouw Nutrition Global Trace Mineral Programme

This can have a significant financial benefit. At Michigan State
University, Oba and Allen (1999) showed that each 1% increase in NDF digestibility increases milk output by 0.25-0.3kg. Using the 65% forage diet in the figure, the hydroxy trace minerals increased the digestibility by 2.9%, which assuming a yield increase of 0.25kg equates to a yield increase of 0.73kg/cow/day.
The overarching theme of ‘Responsible Minerals’ highlighted the
importance of optimizing trace mineral supply to ruminants. Particular emphasis was placed on the importance of considering supplementary trace mineral source, with latest research showing them to have much greater differences than just bioavailability. The Trouw Nutrition GB team is committed to supporting
customers in the development of their own responsible trace mineral strategies supported by the latest research alongside the unique and technologically advanced IntelliBond trace mineral offering.
