According to a study in Journal of Animal Science (2020), Virginiamycin supplementation improved weight gain and feed conversion in broilers without affecting meat quality.
Research in Poultry Science (2021) suggests Virginiamycin may support gut microbiota balance, enhancing nutrient utilization in poultry diets.
Virginiamycin is supplied as a pure antibiotic powder or premix, standardized for activity to ensure consistent performance in feed formulations. The product is tested for potency, microbial contamination, and heavy metals to comply with regulatory standards.
