Live <i>Tenebrio molitor</i> larvae as a dietary supplement for post-weaning piglets: effects on performance and health under diets with different crude protein levels.

Our assessment

This 2026 study investigated whether feeding live mealworm larvae (Tenebrio molitor) to newly weaned piglets could improve their health and growth. The researchers designed an experiment to test this under two different feeding strategies: one with a standard level of crude protein and another with a reduced level. The study did not provide the number of piglets involved or the specific duration of the trial in the available data [Data not available]. Because the sample size is unknown, we cannot fully assess the reliability of the results. "What this means for you" is that this is an early-stage investigation into using insects as a functional feed ingredient for young animals.

How it works

The key idea is that weaning is a stressful time for piglets, often leading to a period of not eating (fasting) that can damage their gut health and make them more vulnerable to disease. At the same time, farmers are under pressure to use less crude protein in feed and find alternatives to standard protein sources like soy. The researchers hypothesized that live mealworm larvae might act as a natural dietary supplement to support gut integrity and overall health during this transition. The study aimed to see if the larvae could help piglets maintain growth and health, especially when the protein level in their diet was lowered [Data not available].

Safety profile

No safety data or adverse event reports were provided in the available information for this specific study [Data not available]. No FDA data or NIH ODS information was referenced for the use of live mealworm larvae as a supplement [Data not available].

Our recommendation

This research is still in its early stages and was conducted on piglets, not humans. The data provided does not include the study's size, duration, or specific findings, so no conclusions can be drawn about its effectiveness for human health. Do not attempt to use live insects as a dietary supplement based on this single animal study. Always talk to a doctor or a registered dietitian before trying any new supplement or major dietary change.
