Effects of dietary of Bacillus coagulans, whey powder, and their interaction on the performance of Lohmann LSL-lite laying hens in the late production phase.
Article in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Due to the need to produce high-quality and healthy eggs, the current experiment was conducted to investigate the impact of dietary supplementation of whey powder (WP), Bacillus coagulans (B. coagulans), and their combination (MIX) on the production performance, egg quality, blood biochemical parameters, and histomorphological parameters of Lohmann LSL-lite laying hens. 144 Lohmann laying hen (75 weeks) were randomly assigned to 4 different dietary treatments, with 6 replications and 6 hens per cage. The hens were fed a basal diet (control, CON), the basal diet supplemented with 1 g/kg WP, 1 g/kg B. coagulans (4 × 106 CFU), and 1 g/kg WP plus 1 g/kg B. coagulans probiotic for 12 weeks. Feed intake and egg weight were not affected by the treatments at any stage of the trial (P > 0.05). No significant interaction was found between WP and B. coagulans in egg quality parameters and blood-biochemical parameters other than malondialdehyde (P < 0.05). The level of malondialdehyde in serum was reduced when WP was used along with B. coagulans compared to when WP was used alone. However, egg production in all periods and egg mass in the first period were affected by the synergistic effect of WP and B. coagulans. Furthermore, FCR was reduced in the first period (75-80 weeks) under the influence of the MIX group compared to the control group or when used alone (P < 0.05). The color of the yolk was increased in the group receiving B. coagulans compared to the control group (P < 0.05). Therefore, in birds fed with B. coagulans, a significant increase in the width of the villi in the ileum was observed (P ≤ 0.05). Interestingly, B. coagulans and WP reduced performance when used alone compared to the control, but improved performance when combined. In conclusion, the simultaneous use of WP and B. coagulans in diet can probably improve the parameters of production performance, FCR, and serum malondialdehyde level at the end of the production period of Lohmann laying hens.
