| description | Caecal microbiota and its modulation play an important role in poultry health, productivity
and disease control. Moreover, due to the emergence of antimicrobial-resistant bacteria, society is
pressing for a reduction in antibiotic administration by finding e ective alternatives at farm level,
such as less intensified production systems. Hence, the aim of this study was to characterise the
caecal microbiota in two di erent broiler management systems, fast and slow-growing, using 16S
rRNA sequencing analysis. To this end 576 broilers were reared in two di erent management systems
(fast and slow-growing). Results showed that Firmicutes represented the dominant phylum for both
systems. At the onset, Proteobacteria was the second prevalent phylum for fast and slow-growing
breeds, outnumbering the Bacteroidetes. However, during the rest of the production cycle, Bacteroidetes
was more abundant than Proteobacteria in both groups. Finally, regardless of the management system,
the most predominant genera identified were Oscillospira spp., Ruminococcus spp., Coprococcus spp.,
Lactobacillus spp. and Bacteroides spp. In conclusion, fast and slow-growing broiler microbiota are in
constant development throughout rearing, being relatively stable at 21 days of age. Regarding the
genus, it should be noted that the three most abundant groups for both systems, Ruminococcus spp.,
Lactobacillus spp. and Bacteroides spp., are related to better productive performance and intestinal health. |
