We sent samples of our dubia roaches to the Barrow-Agee laboratory in Tennessee for testing. Here are the results we received for our Extra Small Dubia Roach Nymphs (these are about 3-5 days old) and Extra Large Dubia Roach Nymphs (these are about 3.5 months old, nearly adults):
| Size | Moisture (%) |
Protein (%) |
Fat (%) |
Ash (%) |
Fiber (%) |
Calcium (mg/kg) |
Phosphorus (mg/kg) |
| Extra Small | 71.5 | 21.4 | 6.1 | 1.3 | 2.6 | 700 | 2600 |
| Extra Large | 65.6 | 23.4 | 7.2 | 1.2 | 2.9 | 800 | 2600 |
As you can see, extra large and extra small nymphs are similar nutritionally, although the larger roaches have less moisture, slightly more fat, and somewhat more protein.
