ISSUE FOCUS 30 FEED & ADDITIVE MAGAZINE December 2023 stress is an underestimated problem. We see it as our mission to raise awareness around oxidative stress. As pressure on the industry is rising to develop more sustainable practices, and climate change puts a risk on lower availability of conventional raw materials, using less ideal circular raw materials will become more common. These raw materials can induce inflammation and oxidative stress and lead to suboptimal performance. It’s Impextraco’s ambition to support its customers via technical services, empowering them to evaluate health problems and propose the corresponding solution, thereby supporting them in adopting sustainable production methods in a cost-effective manner.

He believes Impextraco can have a crucial and holistic role to play in sustainable and profitable animal production via better nutrition and technical services, enhancing the animal’s resilience through optimizing the digestive process. With his background in Bioscience Engineering from KU Leuven and Kyoto University, he wants to leverage nature’s tools to turn one man’s trash in another one’s treasure and is currently engaged in understanding the link between byproducts and oxidative stress. Figure 3. Measuring oxidative stress with plasma biomarkers in sows. (A) Sow plasma thiobarbituric acid reactive substances levels (TBARS in μmol/L) at 7 days pre-farrowing and at weaning. (B) Sow plasma vitamin E levels (μg/mL) at the same time intervals. The trial was conducted with 24 sows (Landrace x Large White) in total and treatment groups of n = 12.
