Hypothesis
What is the optimal concentration of Lactobacillus plantarum CLY-05 for improving the growth and immune response of sea cucumbers?
Conclusion
The study found that an optimal concentration of 1×103 CFU/mL of Lactobacillus plantarum CLY-05 significantly improved the growth rate and immune enzyme activities of sea cucumbers.
Supporting Evidence
- The specific growth rate and weight gain rate were significantly higher in the treatment groups compared to the control group.
- The highest growth rate was observed at a concentration of 1×103 CFU/mL.
- Non-specific immune enzyme activities increased in all treatment groups after immersion bathing.
- The gut microbiota diversity peaked at different times during the study, indicating a dynamic response to the treatment.
Takeaway
Adding a special bacteria called Lactobacillus plantarum to the water where sea cucumbers live helps them grow better and stay healthier.
Methodology
A 49-day feeding trial was conducted with sea cucumber juveniles, using different concentrations of Lactobacillus plantarum CLY-05 to assess growth performance and immune enzyme activities.
Participant Demographics
Sea cucumber juveniles, averaging 8.7 ± 0.6 g in weight.
