Hypothesis
Does adding a blend of essential oils to calf diets improve their immune system and growth?
Conclusion
The essential oils improved the calves' immune and antioxidant systems but did not enhance their growth.
Supporting Evidence
- Calves receiving essential oils showed better feed efficiency.
- Higher levels of immunoglobulin A were found in calves that consumed the essential oils.
- No significant differences in weight gain were observed between the groups.
Takeaway
Giving calves a mix of essential oils can help their immune system, but it doesn't make them grow faster.
Methodology
Twenty-four male Holstein calves were divided into control and phytobiotic groups, with the latter receiving essential oils in their diet for 60 days.
Limitations
The essential oils did not show antimicrobial effects in a controlled environment.
Participant Demographics
Male Holstein calves, approximately five days old.
