ISSUE FOCUS 32 FEED & ADDITIVE MAGAZINE February 2024 content of diluted diet with Rovabio® Advance was similar to that of the typical diet without enzymes (P = 0.98), demonstrating the ability of this enzyme to fully compensate the 3% nutrient dilution (Figure 3). At ileal level, AA digestibility was around 75% across all treatments. The addition of the multi-carbohydrase increased AA digestibility by an average of 3.3% (P<0.001, Figure 4). Rovabio® Advance restored nutrient availability when the nutrient content of a diet was diluted by 3%. This study highlights the importance of considering the entire nutrient matrix when global enzyme solutions are supplemented to diets. SUMMARY To achieve precise nutrition, it’s important to first understand the variability of raw materials. Adisseo’s PNE database, built on in-vivo calibrations, is a reliable resource that can help extract more value from raw materials for acute feed formulations. In addition, evaluating the indigestible fraction of feed and anti-nutritional factors is crucial for precision in animal nutrition. Exogenous enzymes, other than protease, are particularly interesting for improving apparent metabolizable energy and increasing amino acid digestibility in monogastrics. Multi-carbohydrase complexes such as Rovabio® Advance used within a FEEDASE approach have demonstrated significant improvements in protein and amino acid digestibility. Figure 3. Effects on apparent metabolizable energy About Florian Bastit Florian Bastit is the Global Technical Manager of Precise Nutrition Evaluation tool for Adisseo. He earned his MSc in zootechnics and animal nutrition from the agricultural engineering school ESA Angers, France, in 2012 and has been working in animal nutrition since then. He first took a position in a feedmill in France as a formulator and a technical advisor for poultry farmers, then worked for French premixers as poultry specialist in France and abroad for 6 years. Florian joined Adisseo beginning of 2021 as Global Technical Manager, in charge of the PNE tool development and communication. His nutritional background helps him to better understand customers’ needs in terms of raw material evaluation for their feed formulation. About Baris Yavuz Baris Yavuz is animal nutritionist, graduated from animal science in university of Uludag,Turkiye in 2001. Working in feed industry as formulation and quality assurance manager many years, he has joined Adisseo in 2016 as regional technical manager for Eastern Europe, Turkiye and Israel. Yavuz is currently working in Feed Digestibility Department in Adisseo as Scientific Solution Developer, in charge of global technical support. He is the technical consultant of Adisseo’s phytase development project. He is in close contact with Adisseo R&I and different research centers around the world, in order to develop solutions for local and global needs. Figure 4.
