Nutritional protocols that shift ruminal microbiota to improve the feedlot performance of Nellore cattle differing in marbling EPD.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
This study evaluated the effects of high-moisture corn (HMC), rumen-protected fat (CSFA), and organic zinc plus chromium (ZnCr) supplementation, alone or in combination, on feedlot performance, rumen microbiota, carcass traits, and feeding behavior of Nellore cattle with divergent marbling EPD. A total of 150 Nellore yearling bulls were classified into high and low EPD groups and assigned to five diets: (1) fine ground corn (FGC); (2) high-moisture corn (HMC); (3) FGC + calcium salts of fatty acids (FGC + CSFA); (4) HMC + CSFA; and (5) HMC + CSFA + ZnCr (organic zinc and chromium added). The HMC improved average daily gain and gain-to-feed ratio while reducing dry matter intake. The CSFA inclusion enhanced carcass traits and reduced incidence of rumenitis, improving rumen health. The ZnCr supplementation increased glucose availability and dressing percentage, especially in high-EPD animals. Genetic predisposition for marbling influenced dietary responses, with high-EPD bulls showing greater fat deposition and energy efficiency. Rumen microbiota composition was altered by corn processing, CSFA, and ZnCr, particularly affecting specific taxa such as Prevotella, Butyrivibrio, and Firmicutes. Feeding behavior and ruminal morphometry also varied with diet and genetic group. In conclusion, it is recommended to combine HMC and CSFA, while ZnCr proves to be most effective in marbling-genetically predisposed cattle.
