Research on the impact of graphene oxide in feed on growth and health parameters in calves.
Article in Frontiers in toxicology, 2025. 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
Mycotoxins, as feed contaminants, pose serious health risks and cause significant economic losses on farms. The selection of an appropriate and effective adsorbent remains a key challenge for many researchers. Graphene oxide (GO) and its derivatives have garnered interest due to their exceptional physicochemical properties. However, the increasing use of GO necessitates a thorough investigation into its potential toxic impacts on animal and human health, as well as the environment. This study evaluates the effects of GO as a feed additive on calf health. Ten calves (100 ± 6 kg) participated in a 20-day experiment: five in the control group (C) and five in the experimental group (T). The control group (C) received feed without GO, while the experimental group (T) was fed a diet containing 30 g of GO/kg/day. Key parameters evaluated included growth performance, biochemical markers (ALT, AST, ALP), and mineral levels (Ca, P, Mg, K, Na, Cl, Fe, Cu, Zn). The average weight gain was 16.20 ± 0.32 kg in the control group and 15.40 ± 0.26 kg in the GO group, with no statistically significant difference (p > 0.05). Calves fed GO-enriched feed exhibited significant reductions in Fe (p = 0.041) and Zn (p = 0.0006) levels, while Mg increased significantly in the control group (p = 0.029). Liver parameters in group T showed significant increases in ALT (p = 0.022), AST (p = 0.027), and ALP (p = 0.015) after 20 days. Additionally, GPx activity was significantly decreased in the GO group (p = 0.011). These results suggest that GO at a dose of 30 g/kg/day in feed can negatively affect calf health.
