Use of Antibiotics in Equines and Their Effect on Metabolic Health and Cecal Microflora Activities

In the race against deadly diseases, multiple drugs have been developed as a treatment strategy in livestock. Each treatment is based on a specific mechanism to find a suitable drug. Antibiotics have become a fundamental part of the equine industry to treat bacterial diseases. These antibiotics have specific doses and side effects, and understanding each parameter allows veterinarians to avoid or limit the adverse effects of such drugs. Use of antibiotics causes microbial imbalance, decreased microbial diversity and richness in both cecal and fecal samples. Antibiotics reduced metabolites production such as amino acids, carbohydrates, lipids, and vitamins, increased multi-resistant microbes, and gives opportunity to pathogenic microbes such as Clostridium perfringens and Salmonella spp., to overgrow. Therefore, appropriate use of these antibiotics in equine therapy will reduce the adverse consequence of antibiotics on cecal microbiota activities.
