SMART Hydroxy trace minerals a top quality mineral supplement with superior characteristics
By Lien Vande Maele, Orffa
Trace minerals such as copper, zinc and manganese are of great importance for optimal health and performance. An optimal trace element supply, provided by a high quality source of trace minerals is necessary to avoid deficiencies and associated health issues. The new generation hydroxy trace minerals (Excential Smart range by Orffa) are highly available to the animal without negatively influencing stability or uptake of surrounding nutrients, health of the intestinal tract and rumen health and function. They contribute to an optimal trace mineral supply to the animal, which results in improved animal health and performance.
COPPER, ZINC AND MANGANESE
Trace minerals are involved in various complex functions in the metabolism and deficiencies can lead to a variety of disorders. Copper, zinc and manganese play an essential role in several important enzyme activities as co-factor in metalloenzymes. Copper is needed for neutralization of free radicals and red blood cell maturation. Together with zinc it is essential for claw health, supporting bone and cartilage metabolism. Zinc is also important for skin health and immune function. Manganese is important for skeletal development and fertility.
IT’S ALL ABOUT SMART BONDING
Trace minerals are generally categorized as either organic or inorganic, but within these two categories there is a lot of difference. Inorganic sulphate and oxide sources are ionically bound which influences their solubility. Sulphates are highly soluble in water, already at a neutral pH. Released trace minerals are reactive and can degrade other nutrients or form complexes with surrounding minerals and other compounds, reducing their uptake. The new generation trace minerals, hydroxy trace minerals (Excential Smart range) are inorganic but have better bioavailability because of their unique covalent bonds and crystal matrix structure that provides excellent stability and low reactivity. The molecule structure of hydroxy trace minerals is stable and not soluble at neutral pH. The release of the trace mineral atoms starts when pH is decreased and provides a “slow release” effect to the product. This slow release ensures less reactivity and complex formation and results in trace minerals which become available during passage through the small intestine where they can be taken up by transporters to create an optimal trace mineral supply to the animals. Within the category of the organic trace elements, there is also a difference in solubility between sources. The type of bonding of the existing organic complexes can show variability and is very difficult to analyze.
MONOGASTRICS
Recently the allowed supplementation of trace minerals in feed was decreased within the EU, mainly for environmental reasons. These

limitations force nutritionists to take the biological quality of the trace minerals used into account. This counts especially for copper and zinc which are well known in poultry and swine to sustain epithelium health (skin and especially footpad and claw health). The biological quality of hydroxy trace minerals as combined effect on zootechnical performance and on skin parameters was shown in a recent European broiler trial. Ross 308 birds received either 15 and 120 ppm Cu and Zn from sulphates (Control) or a reduced dosage of 10 and 80 ppm Cu and Zn, respectively, in the form of hydroxy trace minerals (XC Smart). Footpad lesions were evaluated following a 0 – 4 score measurement. Results are shown in Figures 1 and 2. The results show the high biological quality towards lower footpad lesion scores for hydroxy minerals, meaning fewer lesions and healthier footpads. Liver copper levels were measured and indicated the higher bioavailability of the hydroxy trace minerals, although lower dosages of these elements were used.
