ADVERTORIAL FEED & ADDITIVE MAGAZINE September 2025 47 Robus Zen is a specialized mixture of aromatic substances and plant extracts designed to limit the negative effects of nervousness in pigs, such as biting or bullying. By promoting calmer social interactions, Robus Zen also helps improve growth performance on swine farms (Figure 2). Both products reflect Techna’s scientific approach, leveraging botanical expertise, advanced formulation, and targeted delivery to support behavioral management in livestock.
