Hypothesis
Combining oregano essential oil (OEO) and yeast cultures (YCs) will modulate rumen microbiota to promote gastrointestinal homeostasis and function.
Conclusion
Feeding calves a mixture of oregano essential oil and yeast cultures led to increased rumen microbial richness and diversity, outperforming separate feeding of these additives.
Supporting Evidence
- Calves fed the MIX treatment showed significantly greater microbial richness and species diversity.
- Pathways associated with metabolism and antimicrobials were enriched in the MIX group.
- Calves fed the MIX had a higher degree of differentiation in microbial community compared to other treatments.
- LEfSe analysis identified several biomarkers that were significantly different in the MIX group.
Takeaway
Giving calves a mix of oregano oil and yeast helps their stomachs have more good bacteria, which is better for their health than just giving them one or the other.
Methodology
Twenty-four newborn, healthy, disease-free, crossbred Simmental male calves were assigned to four treatments: control, OEO, YCs, and a combination of both for 70 days, with rumen fluid collected for analysis.
Participant Demographics
Newborn, healthy, disease-free, crossbred Simmental male calves with a birth weight of at least 35 kg.
