NEWS 20 FEED & ADDITIVE MAGAZINE September 2025 NutriLeads, one of the leaders in plant-based precision prebiotics, announced a new peer-reviewed in vitro study, conducted in collaboration with dsm-firmenich and performed by ProDigest, demonstrating that its proprietary ingredient Benicaros® (carrot rhamnogalacturonan-I, or cRG-I) can potentially deliver consistent gut microbiome benefits in dogs. Published in Microorganisms, the study found that Benicaros® significantly increased levels of beneficial short-chain fatty acids (SCFAs) and selectively stimulated Phocaeicola vulgatus—a keystone SCFA-producing species found in the canine gut. Notably, Benicaros® delivered consistent effects across a diverse population of dogs, regardless of size, breed, or baseline microbiota composition. “This consistent production of SCFAs and the ability to balance the gut microbiota composition, suggests potential health benefits with Benicaros® supplementation in dogs of all sizes,” says Sue McKay, Ph.D., Nutrition & Health Manager at NutriLeads. “These findings highlight Benicaros®’ value as a next-generation precision prebiotic for companion animal health.” The in vitro study evaluated changes in gut microbiota composition and metabolic activity from 18 healthy dogs representing multiple breeds with small (5–10 kg), medium (10–27 kg), and large (27–45 kg) size categories. Each fecal sample was treated with Benicaros® and compared to treatment with inulin (a commonly used prebiotic with a simple molecular structure and low selectivity) or xanthan (a high-selectivity fiber).

Overestimating it can reduce feed intake and growth, while underestimating may limit performance. Traditionally, nutritionists rely on calculated Apparent Metabolizable Energy (AME) values based on ingredient tables and Near Infrared (NIR) analysis. However, these remain theoretical and don’t reflect the animal’s true ability to digest feed under real farming conditions. “The same feed can deliver very different results depending on the farm. We need tools that measure what’s really happening inside the bird, not just on paper,” says an Adisseo representative. To address this gap, Adisseo developed Feed Digestibility Check (FDC): A field-based service that allows poultry professionals to predict the actual AME of feed, based on samples taken on-farm. FDC combines: • Feed + feces sampling on-site • NIR analysis and prediction • A robust model based on 2,000+ samples from 47 in vivo trials Results are delivered in 24 hours via the PNE platform, providing a rapid and practical way to assess real feed utilization, Adisseo highlights. FDC is expected to empower nutritionists to: • Compare AME across farms, diets, or bird types, • Identify energy gaps caused by raw materials, processing, or gut health, • Fine-tune formulation margins and additive strategies, • Improve efficiency and cost control based on what’s actually digested.
