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

backgroundChlorella vulgaris is rich in protein, beneficial fatty acids and antioxidants, making it a promising natural feed additive.

objectivesThis study evaluates the effects of dietary supplementation with the microalgae C. vulgaris on the productivity and egg quality of laying hens.

methodsIn a randomized design, 84 Lohmann Brown hens (47 weeks old) were divided into four groups: a control and three groups receiving 0.1%, 0.3%, or 0.5% C. vulgaris biomass in their feed over 8 weeks. Egg production, laying intensity, egg weight and composition were monitored.

resultsThe 0.5% supplementation significantly increased egg production and laying intensity, without affecting egg weight. Eggs from microalgae-supplemented hens showed largely stable protein, fat and energy content, while dose-dependent trends were observed for cholesterol (increasing up to 275 mg/100 g in the highest dose) and the omega-6/omega-3 ratio (rising from 7.75:1 in CON to 16:1 in CV5).

conclusionsThese results indicate that C. vulgaris supplementation can improve egg yield and potentially enhance nutritional value, though care is needed regarding lipid profile changes. The study supports the use of microalgae as a sustainable feed additive in poultry diets, promoting productivity and contributing to environmentally friendly egg production.
