Effects of probiotic formulations on gastrointestinal tract morphological changes and gut microbiota in Hu lambs.
Article in Open veterinary journal, 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
Background: Gut microbiota plays an important role in the digestive system of ruminants, affecting the health status of Hu sheep and their development and production traits. Factors such as gender, age, diet, and probiotic formulations may influence their compositions. Aim: This study aimed to investigate the morphological changes in the gastrointestinal tract and gut microbiota dynamics during postnatal development of Hu lambs and evaluate the effects of probiotic supplementation. Methods: During the 60-day experiment, rumen, duodenum, jejunum, and ileum samples were collected at 2 hours, 20 days, and 55 days after birth. High-throughput 16S rRNA gene sequencing was employed to analyze microbial diversity, and morphological analysis was conducted to compare differences in the digestive tract surface tissues. Results: The results indicated that the length of the rumen papillae and the height of the villi in the jejunum and ileum continued to increase with increasing age. The overall diversity of the gut microbiota exhibited a gradual upward trend. The microbial diversity indices were higher in the experimental group than in the control group at corresponding time points ( Conclusion: Probiotic supplementation promotes early gastrointestinal tract development, enhances the colonization of beneficial bacteria, and improves microbial diversity in Hu lambs.
