Probiotic supplementation regulated swine growth performance, fecal odor reduction and carcass characteristics by modulating intestinal microbiome.
Article in Animal microbiome, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundUsing probiotics as a substitute for antibiotic growth promoters and reducing odor has received increasing attention in animal science. Despite the extensive investigation into the effects of probiotic administration on swine growth performance and odor reduction by short study durations, the analysis of carcass characteristics and potential mechanistic insights involving gut microbiota and downstream pathways is still few.
methodsA total of 48 crossbred LYD [(Landrace x Yorkshire) x Duroc] piglets (equal numbers of males and females) were randomly assigned to one of four dietary treatments: control (CON), Lactobacillus kefiranofaciens M1 (M1), M1 + Bacillus amyloliquefaciens S20 (SA group) and M1 + S20 + Bacillus subtilis S14 (SAM group). During the nursery phase (4-8 weeks), pigs were pair-housed and monitored for diarrhea. From 8 to 19 weeks of age, pigs were individually housed and fed grower-finisher diets. Growth performance, blood biochemistry, fecal enzyme activity, and odor-related metabolites were assessed at multiple time points. At market weight (~ 110 kg), six pigs per group were slaughtered for carcass and cecal microbiota analysis.
resultsThe results demonstrated that administration of the probiotics led to increased body weight and average daily weight gain, particularly notable during the weaning and finishing periods. Additionally, the SA and SAM groups significantly reduced skatole concentration in feces. Furthermore, probiotic supplementation was associated with increased carcass weight, with the SAM group exhibiting significantly higher tenderloin weight than the CON group. Microbiota analysis revealed taxa exhibiting significant differences in abundance among groups, with corresponding LEfSe findings.
conclusionAdministering Bacillus subtilis S14 and B. amyloliquefaciens S20 (SA group) impacted growth performance, reduced fecal odor, and enhanced pig carcass quality. The identified probiotic strains hold promise as feed additives, offering a potential solution to challenges encountered by the swine industry.
