Prevotella stercorea increases fat deposition in Jinhua pigs fed alfalfa grass-based diets.
Article in Journal of animal science and biotechnology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundFat is a key component of body composition in both humans and animals, with intramuscular fat (IMF) being a critical determinant of pork quality. Higher IMF level enhances meat qualities such as flavor, tenderness, and juiciness, directly influencing consumer preference and market demand. Therefore, identifying microbial biomarkers associated with fat deposition is essential for improving meat quality in livestock and understanding how gut microbiota regulates host metabolism.
resultsIn this study, we examined changes in meat quality, fat metabolism, and gut microbiota during the pig life cycle, from weaning to marketing. We found that Jinhua pig exhibited higher IMF content and marbling score, and higher α diversity of colonic microbial communities. Microbiome Multivariate Association with Linear Models was used to identify the core genera associated with age, breed, and feed, and Prevotella was found to respond to both age and breed factors. The correlation analysis of fat deposition indicators with microbial genera revealed that Prevotella was a potential biomarker in response to IMF. In addition, the P. stercorea DSM 18206 (P. stercorea) was identified in porcine sample and administered to pseudo sterile mouse to examine the effect on IMF deposition. We found that the gavage of P. stercorea with alfalfa-enriched diet led to a significant increase in triglyceride (TG) and IMF contents in muscle. Metabolomic analysis further confirmed P. stercorea may potentially regulate fat deposition through the sphingolipid signaling pathway.
conclusionsWe identified P. stercorea as a potential biomarker linked to higher IMF deposition and validated their role in shaping the gut microbiota and promoting fat accumulation in a mouse model, which correlated with the sphingolipid signaling pathway. These findings provide valuable insights into the role of P. stercorea in regulating fat deposition and metabolic health, offering implications for improving both livestock meat quality and lipid metabolism in humans.
