Effects of Dietary Supplementation With Saccharomyces cerevisiae Yeast Extract on Production Performance in Aged Commercial Laying Hens.
Article in Veterinary medicine and science, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
backgroundBroken-shell eggs in aged laying hens cause great losses to the egg industry. Saccharomyces cerevisiae yeast may improve shell quality by modulating intestinal health and oviduct function.
objectivesThis study was carried out to determine the effects of supplementing Saccharomyces cerevisiae yeast extract (SYE) to the diets of aged commercial laying hens.
methodsA total of 192 Shaver White laying hens aged 105-116 weeks were allocated to four dietary levels of SYE (0, 1.0, 2.0, 3.0 g/kg diet), with 6 replicates of 8 birds each. The experiment was performed in a randomized complete block design.
resultsThe use of different levels of SYE caused a significant linear and quadratic increase in the percentage of laying and daily egg mass production (p < 0.05). Feed intake (FI) in the 3 g/kg treatment was significantly higher than the control treatment in 113-116-week period (p < 0.05). The percentage of eggshell and shell thickness at 105-116 weeks of age (total period) in the 3 g/kg treatment was significantly higher than the control treatment (p < 0.05). Orthogonal comparison of the supplemented SYE against the control treatment also showed that the use of SYE in the diet significantly increased (p < 0.05) the percentage of shell (12.2% vs. 11.4%) and eggshell thickness (0.384 vs. 0.362 mm) compared to the control treatment.
conclusionsThe use of different levels of SYE did not have a significant effect on production performance indicators in old laying hens of the Shaver White strain. It significantly increased the thickness and relative weight of eggshell. Supplementing SYE 3 g/kg diet significantly increased the average eggshell percentage and shell thickness.
