This study evaluated the effects of incorporating spray-dried porcine plasma (SDP) into extruded dog diets. Spray-dried plasma is a functional protein ingredient rich in bioactive compounds that may support digestion, gut health, and immune function. We tested whether adding SDP at different levels (4% as a kibble coating and 4% or 8% within the kibble) would influence nutrient digestibility, fecal metabolites, microbiota composition, serum health markers, and inflammatory and immune biomarkers in adult dogs. Over the feeding period, dogs were monitored for changes in digestion, immune responses, and overall health status. The results showed that SDP inclusion affected nutrient digestibility and gut microbiota composition, suggesting potential benefits for canine health. These findings provide insight into the functional properties of SDP as a dietary ingredient in dog food.
