ACTIVE-MOS Molting and Growth Enhancer Whiteleg shrimp, Litopenaeus vannamei, is among high commercial value aquatic species being cultured recently worldwide. However, because of the rapid development, coupled with the unusual climate change, the shrimp farming has severely suffered significant economic losses due to viruses and vibriosis diseases Use of antibiotics are banned due to the potential development of multi-antibiotic resistance of pathogenic bacteria and residue accumulation in tissues. Economically efficient alternatives are prebiotics ACTIVE-MOS is a natural prebiotic derived from the outer cell wall of a select strain of the yeast Saccharomyces cerevisiae. These are specifically known as mannan oligosaccharides, have been scientifically proven to benefit gut health and the immune systems of shrimp. The action of ACTIVE-MOS is two fold: Immobilizing pathogens present in the gut, and activating the immune system Benefits: * Promote the immune organ development, enhance immune system function, strengthen anti-stress ability, and reduce disease incidence * Promote the beneficial bacteria proliferation, inhibition of pathogenic bacteria in intestinal engraftment, and maintain the body metabolic balance * Speed up growth, increase the rate of weight gain, and lower feed conversion ratio * Strengthen the hematopoietic function
