Abstract
The Lactid Acid Bakteria (LAB) are microflora in the digestive tract which has positive roles in poultry’s health. One of the factors diversity of LAB in the gatrointestinal tract are influenced by feeding factor. The purpose of this study was to analyze the LAB diversity in ileum and coecum after being fed on fermented Chrysonilia crassa molecularly. LAB species diversity was analysed to provide a baseline profile of the microbial community database on the ileum and coecum digestive tract of broiler chicken of control (commercial feed) and treatment (feed with Chrysonilia crassa fermentation) by the method of Terminal Restriction Fragment Lenght Polymorphism The calculated values werethe number of phylotypes, relative abundace, Shannon-Wiener diversity index (H’), evennes index (E’), and similarity. Group of LAB detected in the control group were Lactobacillus delbrueckii (180 bp), Lactobacillus sp. (187 bp), Lactobacillus plantarum (572 bp), uncultured bacterium (87 bp) and unidentified (50 bp, 582bp). The result of this study showed that by feeding on the fermented Chrysonilia crassa feed had resulted in the decreasing of LAB diversity, i.e. ileum (0.66), coecum (0.48) compared with commercial feed (control) that was ileum (0.84), coecum (1.05).
