Hypothesis
The fecal microbiota and metabolites differ between captive and grazing reindeer during summer.
Conclusion
Captive male reindeer have a gut microbiota associated with amino acid and fatty acid utilization, while grazing reindeer have a microbiota that enhances fiber utilization.
Supporting Evidence
- The gut microbiota plays a vital role in nutrient metabolism.
- Fecal microbes responsible for amino acid and fatty acid metabolism were enriched in captive reindeer.
- Grazing reindeer had higher microbial diversity and fiber-utilizing bacteria.
- Captivity alters gut microbiota and metabolite profiles in reindeer.
- Significant differences in microbial community structure were observed between groups.
Takeaway
This study shows that reindeer kept in captivity have different gut bacteria compared to those that graze freely, which affects how they digest food.
Methodology
The study used full-length 16S rRNA gene sequencing and gas chromatography–time-of-flight mass spectrometry to analyze fecal samples from 6 captive and 6 grazing male reindeer.
Limitations
The findings are based on a limited sample size of male reindeer, indicating the need for further studies with larger samples and comparisons between sexes and seasons.
Participant Demographics
12 healthy, three-year-old male reindeer (6 captive and 6 grazing).
