Effects of flammulina velutipes stipe wastes on egg performance, cecum microbiota, intestinal barrier and serum immune response of laying hens.
Article in BMC veterinary research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundImproving production performance and health is the key goal of laying hens farming. This experiment was conducted to examine the effects of Flammulina velutipes stipe wastes (FVW) on the performance of laying hens by regulating cecum microbiota, intestinal barrier and immune response. A total of 108 24-week-old Loman brown laying hens were randomly divided into basal diet group (BD), basal diet supplemented with 0.05 g/kg probiotic compound (PRO), and basal diet supplemented with 40 g/kg FVW. The trial lasted for 8 weeks.
resultsThe results showed that compared with PRO and BD, FVW supplementation decreased feed conversion and increased egg Haugh unit of laying hens (P < 0.05). 16 S rRNA high-throughput sequencing analysis showed that Muribaculaceae, Eubacteriaceae, Synergistes, and Anaerofustis were differentially enriched in FVW-fed laying hens (P < 0.05). In addition, FVW increased the proportion of propionate in cecum, and mRNA levels of TLR-2, TLR-4, MyD88, Muc-2, Claudin-1, and ZO-1 in small intestinal mucosa were increased (P < 0.05). Meanwhile, FVW decreased the content of proinflammatory cytokines in serum (P < 0.05). According to Spearman correlation analysis, Eubacteriaceae and Anaerofustis were positively correlated with propionic acid and anti-inflammatory cytokine ratios, Muribaculaceae and Synergistes were positively correlated with intestinal barrier related gene levels.
conclusionsDietary FVW supplementation improved the performance and egg quality of laying hens, increased the mRNA expression of intestinal mucosal immune factors, and decreased the content of proinflammatory factors in serum, which could potentially be linked to the changes of gut microbiota of laying hens.
