Influence of hydrolyzable vs. condensed tannins supplementation in Liaoning cashmere goats: growth performance, nitrogen metabolism, rumen fermentation, and blood metabolites.
Article in Animal bioscience, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
objectiveThis study was conducted to investigate the effects of hydrolyzable versus condensed tannins on growth performance, nitrogen (N) metabolism, rumen fermentation, and blood parameters in Liaoning cashmere goats.
methodsA control diet and three experimental diets-supplemented with 0.5% chestnut tannin (CT), tannic acid (TA), or quebracho tannin (QT)-were compared.
resultsGoats consuming the QT diet had higher average daily gain and average daily feed intake compared to those on the TA diet (p<0.05). Compared to the control group, the QT group exhibited lower fecal N, urine N, and total N output (g/d, p<0.05), as well as higher N retention (g/d) and N utilization (g/kg N intake) relative to the CT and TA groups (p<0.05). The QT group had lowest urine uric acid level, while the CT and TA groups showed lower creatinine levels compared to the control (p<0.05). Tannin supplementation increased rumen ammonia-N (NH3-N) concentration and reduced protozoa counts (p<0.05). Plasma concentrations of total protein, globulin, superoxide dismutase, catalase, and lysozyme were higher in the QT group than in the CT and TA groups (p<0.05).
conclusionThese results suggest that condensed tannin provides greater advantages than hydrolyzable tannin on growth, N balance, and antioxidant function at equivalent dietary inclusion levels.
