Enhancing sheep rumen health with Przewalskia tangutica: boosting fermentation and microbial diversity in saline-alkali sown pastures.
Article in Animal microbiome, 2026. 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
backgroundLivestock grazing on saline-alkali pastures frequently encounter nutritional challenges due to inadequate forage quality and imbalanced rumen function. Phytogenic feed additives, which are abundant in bioactive compounds such as tropane alkaloids and flavonoids, have demonstrated potential in enhancing rumen fermentation and improving animal performance. Przewalskia tangutica, a desert plant rich in these compounds, remains largely unexplored concerning its effects on microbiota and metabolism in sheep under saline-alkali conditions. This study aims to evaluate the impact of graded supplementation of Przewalskia tangutica on rumen fermentation, microbial dynamics, digestive enzyme activity, and growth performance in sheep grazing on degraded saline-alkali pastures.
resultsSupplementation with Przewalskia tangutica significantly increased the average daily gain (ADG, P < 0.001) and reduced the feed conversion ratio (FCR, P < 0.001). The high-dose group (HP) exhibited the highest ADG at 139.94 g/d. Additionally, the concentrations of total volatile fatty acids (VFAs), including acetate, isobutyrate, and butyrate, were significantly elevated (P < 0.001), peaking at 1.46 mmol/L in the HP group. Furthermore, the activities of amylases, lipase, cellulase, and protease increased significantly (P < 0.05). While the bacterial alpha diversity remained unchanged, beta diversity analysis revealed structural shifts characterized by increased abundances of Verrucomicrobiota, Proteobacteria, and Fibrobacterota (P < 0.05). Fungal diversity also increased under the HP treatment (P < 0.05), whereas a reduction in Cladosporium abundance was correlated with enhanced fiber degradation. Moreover, microbial co-occurrence networks demonstrated more balanced interactions in the treated groups, with significant correlations among taxa, enzymes, and VFAs.
conclusionsPrzewalskia tangutica improves rumen fermentation and sheep performance in saline-alkali environments through targeted modulation of microbial communities and enzymatic activity, particularly at the high dose, significantly improved sheep growth performance by increasing average daily gain and reducing the feed conversion ratio, suggesting a sustainable strategy for livestock production in challenging ecosystems.
