Popis: The study was performed to investigate the effect of hydroalcoholic extract of different thyme species on performance, intestinal morphometry, nutrient digestibility and immune response of male broiler chickens. A total of 160 day-old Ross 308 broiler chicks were randomly allotted to five treatments including a control basal diet or diets supplemented with 0.1% of four thyme extracts (Thymus daenensis, T. kotschyanus, T. lancifolius, and T. transcaspicus) with four replicates of eight birds each.
