Product Description
Virginiamycin is a high-potency antibiotic commonly used in animal feed to improve growth performance and feed efficiency. Globally, Virginiamycin is recognized for its selective activity against Gram-positive bacteria, contributing to better gut health and nutrient absorption in livestock. It is widely utilized in poultry, swine, and aquaculture industries, making it a staple for B2B buyers seeking reliable feed additives with proven efficacy Veterinary And Animal Health
Content Note: Prepared by our technical team based on current scientific literature. Health claims comply with FDA/EFSA guidelines. Last reviewed: April 2026
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.
