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

backgroundA prebiotic is defined as an indigestible feed substance that beneficially affects the host by selectively stimulating the growth and/or activity of one or a limited number of bacteria in the large intestine, thereby improving host health and products.

objectivesThis study was conducted to determine the effects of supplementing prebiotic fructooligosaccharide (FOS) to the diets of Hy-Line W-36 laying hens.

methodsA total of 168 Hy-Line W-36 laying hens were allocated to four dietary levels of FOS (0, 1.0, 2.0, 3.0 g/kg diet), 6 replicates of 7 birds each during 63-74. The experiment was performed using a completely randomized design.

resultsProductive performance was not significantly affected by the FOS supplementation. Body weight gain was linearly decreased with increasing FOS levels in the diet (p < 0.01). However, eggshell strength, shell thickness and Ca and p percentages were not significantly affected, as were anti-sheep red blood cell titres, blood parameters and blood metabolites. In the first period of the experiment (63-65 weeks), shape index and Haugh unit at the dose of 3.0 g/kg FOS were significantly increased and decreased in comparison with control, respectively (p < 0.05). In the third and fourth periods (69-71 and 72-74 weeks of age), the FOS had no significant effect on the internal egg quality traits. Furthermore, FOS had a linear decrease in the most saturated fatty acids (SFAs), including myristic, palmitic, margaric and stearic fatty acids; some of the mono-un-SFA (MUFA; palmitoleic and ginkgolic acids), and poly-unsaturated fatty acids (γ-linolenic and eicosatrienoic).

conclusionsSupplementing different levels of FOS to the diet of commercial laying hens had no significant effect on the layers' performance, immune response and blood parameters, whereas there was a significant effect on some of the internal egg quality traits and egg yolk fatty acid contents.
