INTRODUCTION
Maintaining intestinal health is a critical factor for optimal performance in poultry. The gastrointestinal tract plays a central role in digestion and represents the first line of defense against pathogens. In this context, natural extracts have gained increasing importance in poultry production as promising alternatives to conventional feed additives (Chen et al., 2022; Latek et al., 2022). In particular, grape and olive extracts stand out for their capacity to support intestinal health, mainly through antimicrobial effects that help control enteric pathogens, modulate gut microbiota, and contribute to improved intestinal functionality even under challenging scenarios such as mycotoxicosis (Abdel-Moneim et al., 2020; Qi et al., 2023).
OBJECTIVE
The aim of this study was to identify the bioactive compounds present in a liquid solution (LS) based on grape and olive extracts, and to evaluate its in vitro antimicrobial activity.
MATERIALS AND METHODS
RESULTS
CONCLUSIONS
These results demonstrate that the liquid formulation is rich in antioxidant and anti-inflammatory bioactive polyphenolic compounds, and exhibits potent in vitro antimicrobial activity against enteric pathogens, suggesting its potential to enhance intestinal health by supporting microbiota balance, ultimately improving poultry growth and performance.
