Trace minerals are essential to supporting ani- mals’ potential, productivity and well-being.
trace minerals use a series of covalent bonds to increase the trace mineral’s availability. This structure allows significantly greater amounts of trace metal to be delivered to the intesti- nal tract for absorption, supporting animal performance and well-being. Unlike organic trace minerals, hydroxy trace min- erals have much higher metal potencies and are priced much lower (Figure 1, C.M. Parsons, Univ. of IL.)
Getting the “precision trace mineral” programme right Beyond a trace mineral’s bioavailability, nutritionists must en- sure that the mineral is accurately and consistently delivered to livestock. Given the many steps involved in adding ingredients to an animal’s diet, this can be a challenge, as the cumulative total of trace minerals in a tonne of complete feed is typically less than 0.5 kg (0.05%). A precision trace mineral nutrition programme involves selecting an optimal level of the most bio- available source of trace minerals, accurate weighing, and add- ing these minerals to the feed, thus ensuring that a homoge- nous blend of the right ingredients is available for the animal.
The advantage of combination For decades, Trouw Nutrition has focused on developing, vali- dating and implementing precision trace mineral nutrition programmes that support animal efficacy and profitability. Trouw Nutrition is now introducing IntelliOpt. IntelliOpt is an innovative species-specific trace mineral solution which uses both organic (Zn, Cu, Mn, Fe, Se) and hydroxy (Zn, Cu, Mn) trace minerals sources together in a synergistic blend with other essential trace minerals (Co, I) to consistently deliver high metal bioavailability at a cost-effective price.* A key advantage of this solution is the combination of both hydroxy (Selko IntelliBond) and organic (Selko Optimin) trace mineral sources in one convenient package to further im- prove animal performance during periods of high productivi- ty and/or challenge. The synergy lies in the complimentary release profiles, allowing animals to absorb more trace
minerals throughout their intestinal tract. A meta-analysis of four trials showed that a combination of 70 ppm of zinc from IntelliBond, and 10 ppm of zinc from Optimin significantly improved final body weight and FCR of broilers, demonstrat- ing the clear advantage of combining both sources (Figure 2).
Putting it all together As nutritionists and farmers seek improvements in sustaina- ble food production, the need to match animal requirements with research validated products and programmes is becom- ing more important. Achieving this objective using a preci- sion trace mineral nutrition programme such as IntelliOpt is a proven solution that can result in improved animal productivity, well-being and environmental compliance.
*Trouw Nutrition is working with its global hubs to coordinate the introduction of IntelliOpt over the next 12 months. In the meantime, they will continue to offer customers the proven ben- efits of both IntelliBond and Optimin as an essential component of their nutritional programmes. More info
