ABSTRACT

Prevention of silkworm diseases through induction of different probiotics has been studied. Seven probiotics, Lactobacillus acidophilus, L. sporogenes, L. rhamnosus, Saccharomyces boulardii, Streptococcus faecalis, Lactic acid bacillus and Bifidobacterium longum along with Fructo- Oligo Saccharides (Prebiotic) have been used as Synbiotic studies in in vitro. In vivo screening of Synbiotic preparation against common silkworm pathogens have been done. Three trials silkworm rearing for selection of effective synbiotic formulation has been conducted. From this study,  it is observed that a synbiotic formulation in combination with Lactobacillus sporogenes , Saccharomyces  boulardii and Streptococcus faecalis performed better in improving larval and cocoon character like, 5^th stage larval weight (7.2%) , Effective Rearing Rate (12.4%), Single Cocoon Weight (5.2%), Single Shell Weight(12.1%), Shell Ratio % (6.93%)  . The data has been analyzed statistically and it is found that the result of the above cocoon character has significant difference @1.0% level. Therefore, effort has been taken for making a Synbiotic combination consisting of Lactobacillus sporogenes , Saccharomyces  boulardii  and Streptococcus faecalis  to study the synergistic effect of the above three bio-molecules to control silkworm diseases, thereby increases the cocoon productivity. Seven treatments in different combinations of above three probiotics have been studied on different breeds / hybrids of silkworm, B.mori during different seasons to identify more effective synergistic combination of immunogen for immunization of silkworm to control the silkworm diseases.
