Encapsulated Bacillus sp. THPS1, a novel thermophilic probiotic, enhances productivity and metabolic health in laying hens.
Article in Poultry science, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 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
Encapsulated probiotics, sustainable alternatives to antibiotic growth promoters in poultry production, enhance productivity and physiological health. Comparative evidence on strain-specific encapsulated Bacillus probiotics and their combined effects on production performance, egg quality, metabolic indicators, and hematological profiles in laying hens is insufficient. This study evaluated three encapsulated Bacillus strains (THPS1, PWR01, and OYNH19) for sporulation, encapsulation, and spore release efficiencies. A feeding trial in laying hens supplemented with 1 × 10⁶ spores/g feed was conducted over 4 weeks. Production performance, egg quality traits, serum lipid profiles, stress hormone levels, and hematological parameters were assessed. Sporulation and encapsulation efficiencies were consistently exceeded 96 %, while spore release efficiency exhibited significant variation across strains. OYNH19 demonstrated lower release efficiency compared to THPS1 and PWR01 strains (p = 0.042). Dietary supplementation with THPS1 significantly enhanced feed conversion ratio (FCR) (0.23 ± 0.01), resulting in a 23 % reduction compared to the control and other probiotic treatments (p = 0.001). Notably, egg production rate and body weight (BW) remained unchanged. However, egg weight (EW) was exhibited a significant increase in the THPS1 group by week 4 (65.22 ± 4.67 g; p = 0.041), without any adverse effects on eggshell or internal quality traits. Furthermore, THPS1 supplementation was associated with reduced serum triglyceride concentrations and distinct multivariate clustering, indicating coordinated alterations in production, metabolic, and hematological variables. Overall, encapsulated Bacillus sp. THPS1 demonstrated superior efficacy in optimizing feed efficiency while maintaining physiological stability.
