Thyme 59.5mg pastilles

ObjectivesNatural alternatives to synthetic additives are being explored as a means to enhance laying hen performance and egg quality. The study conducted a systematic review and meta-analysis to evaluate the effect of dietary supplementation with Thymus vulgaris (thyme) on productive performance and egg quality in laying hens.MethodsA comprehensive search of databases identified 18 eligible studies. Data were analysed using random-effects models, with subgroup analyses based on the thyme form (powder, essential oil, extract) and supplementation duration (≤ 8 weeks, > 8 weeks). The unstandardized mean difference was used to calculate the effect size, and confidence intervals were generated to estimate the range of the true effect size.ResultsThyme significantly improved egg weight, egg mass, yolk colour, yolk index and shell thickness (p 8 weeks) yielded greater benefits for egg mass and weight, whereas shorter durations (≤ 8 weeks) improved shell thickness.ConclusionsThese findings suggest that thyme supplementation, particularly in powdered form and over extended periods, can enhance egg quality, offering a natural alternative to synthetic additives. This research demonstrates thyme's efficacy as a phytogenic feed additive, offering a natural solution to improve egg quality and meet the rising demand for sustainable and high-quality poultry products.SummaryThyme supplementation improves egg weight, egg mass, yolk colour and shell thickness in laying hens. Powdered thyme shows the most significant benefits for egg weight and mass. Longer supplementation periods (> 8 weeks) enhance yolk colour and egg quality traits. Thyme offers a natural, sustainable alternative to synthetic feed additives in poultry production.
