TL;DR
These findings provide insight into the functional properties of SDP as a dietary ingredient in dog food
1. 연구 배경 및 동기
- 다루는 문제: Spray-dried plasma (SDP) is a high-quality protein source with functional properties that support gut health, immune function, and digestibility
- 기존의 공백 / 왜 필요한가: Although its benefits have been demonstrated in various animal species (e.g., swine, poultry, rodents, and fish), further research is needed to understand its specific effects in extruded diets and canine health. This study evaluated the effects of incorporating SDP from swine, in partial replacement of chicken meal, into extruded diets on nutrient digestibility, fecal metabolites, microbiota composition, serum chemistry, and inflammatory and immune biomarkers in adult dogs
2. 관련 연구
- 기존 연구 흐름: Feeding 8% SDP maintained overall nutrient digestibility but reduced total dietary fiber digestibility (P < 0.05)

- These findings provide insight into the functional properties of SDP as a dietary ingredient in dog food.
4. 제안 방법론
- 전체 접근 논리: Fecal concentrations of short-chain fatty acids, particularly propionate, were higher in dogs fed the 8% SDP diet (193
- 단계: Additionally, a linear reduction in protein fermentation byproducts, mainly indole metabolites, was observed, suggesting a beneficial shift in microbial metabolism (P < 0.05). Inclusion of SDP also modulated fecal microbiota composition, with changes across several genera and increases in beneficial genera such as Lactobacillus, Streptococcus, and Catenibacterium, while also affecting beta-diversity (P < 0.05)

제안 기전(인과 사슬): This study evaluated the effects of incorporating spray-dried porcine plasma (SDP) into extruded dog diets. SDP 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
