Diversity of Intestinal Bacterial Microbiota of Indigenous and Commercial Strains of Chickens Using 16S rDNA-Based Analysis.

摘要: The objective of this study was to assess the relative abundance bacteria microflora in different segments gastrointestinal tract (duodenum, jejunum, ilium, and cecum) indigenous (local Omani) commercial (Cobb 500) chicken strains. Birds were raised under an intensive management system fed a nonmedicated corn-soybean meal diet from Day 0-35 days age. Using 16S rDNA-based analysis showed that both breeds birds Bacilli most abundant class duodenum, ileum. Local Omani chickens had significantly higher numbers Clostridia at time periods. Actinobacteria found reached 54.9% jejunum 35 Cobb 500 versus only 5.42% chickens. bacterial microbiota differed (p < 0.05) across intestinal two strains, suggesting each region developed its own community abundances these quite different.
