ISSUE FOCUS 34 FEED & ADDITIVE MAGAZINE February 2023 from the mixer. Samples should be pulled from the middle portion of the mix and analyzed using wet chemistry protocols. To consistently achieve precise mixing, establish a defined protocol clearly specifying trace mineral selection and weighing criteria along with when the trace mineral(s) is sequenced within the mixing process and mixing time. Evaluating the four trace mineral considerations described above can help poultry producers capture the full investment of their precision nutrition strategy. ACHIEVING A HIGHER LEVEL OF PRECISION TRACE MINERAL NUTRITION To help producers mitigate the effects of the challenges described above and support both animal performance and producer economics, Selko developed IntelliOpt — a cost-effective solution to achieve a higher level of precision trace mineral nutrition in premixes and complete feeds. The IntelliOpt product portfolio offers producers, pre-mixers, and compounders a species-specific blend of IntelliBond and Optimin, precisely formulated to deliver optimal animal performance. All IntelliOpt blends are formulated based on the knowledge and insights of leading industry groups and academic professionals with a keen eye on ensuring optimized animal productivity and well-being. Individual blends are manufactured by Selko to ensure that all critical nutrients are present in the right form and amount to support trace metal availability to animals. The selection of a trace mineral source is an important decision to support productivity and health. However, knowing how that source was added and mixed, along with its impact on other essential nutrients in the feed, are equally important parts of an effective precision nutrition strategy. Ultimately, the best trace mineral source is of little value if it is not consistently delivered in the correct amount and form required for peak animal performance and health. About Gavin Boerboom Gavin Boerboom received the master’s degree in health food innovation management from Maastricht University in 2016. In 2016 he started working at Nutreco where he combined a full-time researcher job with a PhD position on trace mineral nutrition at Wageningen University. After finishing his PhD, Gavin now holds his current position as a technical commercial manager at Selko, the feed additive brand of Nutreco. In this position he supports primarily the North American and European mineral portfolio of Selko, with his expertise on trace mineral nutrition, experimental designs and monogastric nutrition.
