The Influence of Ethanolic Extract of Hypericum Perforatum (St. John's wort) on Growth Performance, Serum Metabolites, Fat Deposition, Immunity, and Lipid Peroxidation in Broiler Chickens.
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 2 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
backgroundHaving bioactive components such as hypericin, hyperforin and quercetin has enabled Hypericum perforatum (HP) to show antioxidant, antiviral and hypocholesterolemic effects in different animal species.
objectivesThis study aimed to investigate the effects of different levels of Hypericum perforatum extract (HPE) additions on performance, immune response, serum metabolites, and lipid peroxidation in broiler chickens.
methodsA total of 250 one-day-old broiler chicks were randomly allocated to five treatments with five replicates and ten chicks each. Experimental rations consisted of a basal diet with no supplement (control group) and a basal diet with 0.1%, 0.5%, 1%, and 1.5% HPE.
resultsResults showed that the addition 1.5% HPE in the broiler diet increased high-density lipoproteins (HDL) compared to the control diet. While the total cholesterol (TC) was significantly reduced by HPE supplementation, only feeding 1% and 1.5% HPE significantly lowered the low-density lipoproteins (LDL). HPE addition to the diet significantly reduced abdominal and breast fat at 0.5%, 1%, and 1.5% levels. However, thigh fat was significantly decreased by dietary all HPE levels supplementation. Moreover, in the group fed with 1.5% HPE, the immunoglobulin G (IgG) and thymus weight significantly increased compared to the control group. Compared with the control group, HPE-fed groups showed significantly lower malondialdehyde (MDA) concentrations in breast muscle. The total antioxidant capacity (T-AOC) was improved significantly by HPE supplementation.
conclusionsIn general, while there was no significant difference among treatments in the case of growth performance parameters, dietary supplementation of HPE at 1.5% was the most effective dose to improve serum biochemical metabolites, fat metabolism, immune response, and oxidative stability in broiler chicks.
