Influence of poly germander (Teucrium polium) and watercress (Nasturtium officinale) extract on performance, carcass quality and blood metabolites of male broilers

This experiment was conducted to study effect of poly germander (Teucrium polium) and watercress (Nasturtium officinale) extracts on performance and serum biochemistryl of broilers. Two hundred and forty male Ross broilers (were alloted into 4 diet treatments for 42 days. The birds were fed their standard feed without any addition (control) or with addition of 200 ppm of poly germander extract (T1), 200 ppm watercress extract (T2) or 200 ppm of the combination of both components (T4). No significant change was observed in term of growth parameters and blood biochemistry, however, abdominal fat decreased significantly in the watercress and the combination extracts supplemented groups. The study highlighted the potential of these herbal extracts to improve body performance and carcass quality of broilers.
