Impact of Dried Thyme Leaf Meal on Production Performance, Egg Quality and Blood Parameters of 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 1 paper.
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
backgroundThe use of commercially extracted phytogenic compounds to maintain poultry health and productivity in the absence of in-feed antibiotics is prohibitively costly in developing countries.
objectivesThe goal of the study is to determine the effect of dietary supplementation with Thymus schimperi leaf meal (TLM) on production performance, egg quality and haemato-biochemical parameters of Bovan brown layers.
methodsA total of 96 laying hens at 25 weeks of age were randomly assigned to 4 treatments with 6 replications each. The treatments include the control (standard commercial laying diet), TLM1.5 (control + 1.5% TLM), TLM2.5 (control + 2.5% TLM) and TLM3.5 (control + 3.5% TLM). Egg production, feed intake and feed conversion ratio were recorded for each replicate. Two eggs per replication were used to measure internal and external egg quality traits on a monthly basis. At the end of the trial, blood samples were collected from 2 birds/replicate for the determination of albumin, uric acid, aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, luteinizing hormone, prolactin and progesterone.
resultsAll blood parameters were within the normal ranges of the breed. Egg production, feed conversion ratio, internal egg quality traits and external egg quality traits of hens fed diets containing 2.5% TLM were significantly higher than the control. Furthermore, diets containing 2.5% TLM led to a significantly reduced feed conversion ratio compared to all other dietary treatments.
conclusionsIn conclusion, 2.5% TML is recommended to improve egg production and egg quality without adverse effect on hen health.
