Sanolife PRO-F FMC is a mixture of a high number of micro-organisms that allows fast disease control, gut microflora colonization and improvement of feed use. These microorganisms have been selected for their ability to inhibit pathogenic bacteria, produce enzymes and improve feed use and growth rate. They do this under a wide range of salinities (0 to 60 g/l), temperature and (an)aerobic conditions. The formulation has been designed for application at the feed mill.
