This study identified three distinct gut microbial enterotypes in broilers, revealing specific microbial compositions associated with nutrient metabolism and fat deposition. These findings advance our understanding of broiler gut health and its impact on performance.
Area of Science:
- Animal Science
- Microbiology
- Nutritional Science
Background:
- Enterotypes classify gut microbial communities, but their identification and role in poultry remain underexplored.
- The function of the foregut microbiota in poultry nutrient digestion and absorption requires further investigation.
Purpose of the Study:
- To identify duodenal enterotypes in broilers.
- To explore the impact of these enterotypes on broiler performance and nutrient metabolism.
Main Methods:
- 16S rRNA high-throughput sequencing of duodenal microbial communities from 206 broilers.
- Metabolomic analysis to assess nutrient metabolism.
- Statistical analysis to compare enterotypes and correlate microbial composition with phenotypic data.
Main Results:
- Three duodenal enterotypes (ET1, ET2, ET3) were identified, with significant differences in alpha-diversity.
- Enterotype 2 (ET2) was characterized by high relative abundance of Ochrobactrum and Rhodococcus, positively correlated with specific carbohydrates and lipids.
- ET2 broilers exhibited higher triglyceride levels, subcutaneous fat thickness, and abdominal fat weight compared to other enterotypes.
Conclusions:
- This study confirms the presence of enterotypes in broilers.
- The dominant microbes in ET2 may play a key role in plant polysaccharide degradation and utilization, influencing lipid metabolism and fat deposition.
- Findings provide a basis for future research on gut microbiota regulation to enhance broiler growth and well-being.
