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

Chitosan nano-selenium has gained attention for its potential benefits in poultry nutrition, but its effects on the production performance, egg quality, and selenium deposition in laying hens have not been fully explored. This study aims to fill this gap by evaluating the impact of different doses of chitosan nano-selenium on laying hens, by focusing on optimizing both production performance and selenium enrichment in eggs, which could have significant implications for poultry nutrition and human health. In this experiment, 600 (48-week-old) Lohmann breeders were randomly assigned to five experimental groups, each receiving varying levels of chitosan nano-selenium supplementation (0.1 mg, 0.3 mg, and 0.5 mg selenium/kg), with a blank control group included for comparison. Production performance indicators, egg quality parameters, and selenium content in various tissues and eggs were measured across groups. The results showed that while cumulative egg production slightly decreased in the supplemented groups, significant improvements were observed in egg quality, particularly in the Haugh unit and yolk index at week 4, along with enhanced egg stability during storage. Furthermore, selenium supplementation resulted in higher selenium concentrations in the serum, liver, oviduct, ovary, and eggs, with the 0.3 mg selenium/kg group showing the most significant increase. In conclusion, the supplementation of 0.3 mg selenium/kg of chitosan nano-selenium effectively enhanced egg quality, improved storage stability, and increased selenium deposition in laying hens without negatively affecting overall production performance. This study underscores the potential of chitosan nano-selenium as a promising nutritional strategy to optimize poultry health and improve the production of selenium-enriched eggs.
