ISSUE FOCUS FEED & ADDITIVE MAGAZINE December 2025 41 TRIAL 1- PetArom Beef P Without Digest To evaluate the intrinsic effect of PetArom independent of digest, dogs were offered: • Diet A: Premium dog food without digest • Diet C: same diet + 20 g PetArom Beef P per 100 kg feed (both diets digest-free) PetArom alone significantly improved palatability. Preference shifted from approximately 50/50 for the control to ~70/30 in favour of the PetArom diet, demonstrating a clear increase in spontaneous acceptance and voluntary intake. For comparison, the positive control containing 3 % digest achieved ~84/16 versus Diet A. This indicates that, although PetArom delivers a clear palatability benefit on its own, digest, however, continues to be the major intake-driving component. Conclusion PetArom enhances voluntary intake on its own, but is positioned as a complement, not a replacement, to digest (Figure 2). TRIAL 2 - Synergy: PetArom Combined With Digest To assess the additional palatability benefit of PetArom when combined with digest, in a digest-free comparison, a standard two-bowl preference test was conducted in 20 adult dogs fed once daily. Diets offered: • Diet A: Premium dog food without digest • Diet D: Premium dog food with 3% digest + 20 g PetArom Beef P / 100 kg feed Results showed that preference increased to approximately 94/6 in favour of Diet D. For context, in the baseline validation, Diet B (base diet with 3% digest) had previously shifted preference from roughly 50/50 to ~84/16 versus the same digest-free control (Diet A). This demonstrates that supplementing digest with PetArom provides an additional ~10-percentage-point improvement, further increasing spontaneous intake and first-choice selection beyond the effect of digest alone. By strengthening the savoury, meaty aroma profile, PetArom enhances the initial Figure 2.
