abstract
Ban on the use of antibiotics as growth promoters in the European Union since January 1, 2006 (EC 2001) urged the scientist to find a suitable alternative to antibiotics. To overcome these problems, the use of Probiotic, prebiotics and combination of probiotic and prebiotic came up as a good alternative to antibiotics. Prebiotics as selectively fermented food ingredients that improve host health by targeting indigenous components thought to be positive. The prebiotics mostly consist of dietary fibers and oligosaccharides. Probiotics are defined as “live microorganisms which, when administered in adequate amounts, confer a health benefit on the host” The probiotics and prebiotics help in improving the host (animal) health status by reducing the pathogen load through better resistance to pathogenic bacteria colonization and enhanced host mucosa immunity.
