Respiratory problems in pigs is a complex and economically significant cause of production loss. Higher stocking densities is associated with respiratory problems. As the stocking density increases, the air quality diminishes inside the shed. As a result, more pigs are at risk of exposure to respiratory problems. Preventing pigs from respiratory symptoms and maintaining the respiratory health are what the purpose we developed Meatafac. To achieve optimum benefits, Meatafac is composed of quantified active ingredients from the qualified Flos Lonicerae Japonicae and Radix Scutellariae. Rigorous production process ensures that active ingredients will be retained and prevents impurities and molds in medicine.
