In layer units, hydroxy minerals have been shown to increase


egg production and improve egg shell quality, leading to a reduction in breakages. In addition, they help reduce the impact of heat stress on egg production rates. Figure 2 shows the benefits of replacing oxides with Intellibond both on rate of lay and feed conversion. In broilers, improved breast meat percentage has been observed along with a positive effect on feed conversion and average daily gain. In addition to the beneficial effects on animal performance,


Intellibonds can also improve the stability of other feed ingredients. For example, copper sulphate is known to reduce the stability of α-tocopherol in feed. Feeding Intellibond copper as an alternative reduces this degradation by up to 13% (Figure 3). This improves shelf life and nutrient stability, increasing overall nutrient availability

structure and the strength of the chemical bonds, the production of which is a significant challenge, particularly if a highly consistent and high-quality product is to be achieved. Feed compounders and premixers should be aware of the importance of strict production control measures that need to be in place to ensure a highly stable and effective product. Intellibond also has an unrivalled wealth of research, much of it


published, from over 150 studies obtained over 20 years demonstrating the effectiveness of the brand specifically and its benefits in terms of animal performance across multiple species. This research is specific to the effectiveness of the crystal structure of Intellibond, so formulators and nutritionists should be aware of this when looking into or being presented with generic hydroxy mineral research. Products must meet EU compliance for the content of heavy


metal, dioxin and dioxin-like compounds. Samples of some hydroxy mineral products have shown levels of 2-5 times the regulatory limit, putting a huge question mark over their quality and toxicity. Selko IntelliBond trace minerals have been produced to ensure


superior characteristics during feed manufacture. Patented Optisize Large Particle Technology helps ensure there 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


Outstanding quality, handling and stability With a number of hydroxy mineral brands now available on the market worldwide, it is important to be aware that whilst the empirical formulae of the products may be the same, careful control of the production process and quality control measures are critical for optimal animal performance. At the heart of hydroxy mineral performance is the crystal


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.
