This indicates that the regular dose already provides strong and meaningful palatability benefits, and that doubling the inclusion rate leads only to marginal additional gains under the conditions of this specific study. Effects may vary in different trials or feeding environments. Conclusion 20 g/100 kg remains the optimal, cost-effective inclusion rate, as higher doses provide only marginal additional benefits (Figure 5). CONCLUSION AND OUTLOOK The study clearly demonstrates that PetArom Beef P delivers consistent and meaningful improvements in palatability — both as a standalone solution and through pronounced synergy with digest. By enhancing aroma depth for dogs while refining Figure 4. Effects of adding PetArom Beef P to a digest-based diet, demonstrating a clear sensory uplift and enhanced palatability on top of digest Figure 5. Effects of increasing PetArom Beef P dosage in a digest-based diet, showing only marginal gains beyond the standard inclusion rate
