1 · What the graph read from it

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.

2 · The registry

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

The use of agroindustrial byproducts in ruminant nutrition is gaining increased attention because of economic and environmental benefits and their potential to enhance ruminal function and animal performance. However, the effect of these byproducts on ruminal microbiome and fermentation has been scarcely investigated. This study aimed to evaluate the effects of replacing conventional feeds with agroindustrial byproducts (18:18:8 mixture of corn dried distillers grains with solubles, dry citrus pulp, and exhausted olive cake) on the ruminal microbiome and fermentation parameters of sheep. Four rumen-fistulated Lacaune sheep were used in 2 experimental periods, receiving mixed diets composed of 50% alfalfa hay and 50% of either a control concentrate (CON diet) or a concentrate with agroindustrial byproducts (BYP diet). Ruminal samples were collected at 0, 3, and 6 h postfeeding to assess microbial composition and fermentation parameters. Diet significantly influenced the ruminal microbiome, but the effect of individual sheep was more pronounced than that of the diet. Sampling time also influenced the ruminal microbiome. The inclusion of agroindustrial byproducts in the concentrate did not significantly alter ruminal fermentation parameters. However, the BYP diet led to more steady ruminal fermentation, preventing large fluctuations in total VFA and ammonia concentrations, likely the result of a broader range of fermentable substrates present in the BYP concentrate and changes in ruminal microbiome. These results may indicate improved synchronization of nutrient availability for ruminal microorganisms. Overall, replacing conventional feed ingredients with agroindustrial byproducts promoted microbial diversity and improved ruminal fermentation, potentially leading to increased dairy ruminant performance.
