What Are Natural Dry Mealworms?
Life Cycle of Mealworms
Mealworms go through four main stages in their life cycle: egg, larva, pupa, and adult beetle. It all starts with tiny eggs laid by adult beetles. These eggs hatch into larvae, which are the mealworms you’re familiar with. The larval stage lasts about 10 weeks, during which they grow by feeding on grains like wheat bran and maize. Afterward, they transform into pupae, a resting stage where they don’t eat or move much. Finally, they emerge as adult beetles, ready to start the cycle again.
Mealworms are efficient feeders. They only need 2 pounds of food to produce 1 pound of mealworms. Compare that to cattle, which require 8 pounds of feed for the same output. Plus, mealworms thrive in small spaces and can be raised vertically, making them perfect for large-scale production. Their feed conversion ratio (FCR) is as low as 2.2, far better than cattle’s 8.52.
| Metric | Value |
|---|---|
| Average rearing duration | 100 days |
| Feed composition | Wheat bran (70%), maize (12%), brewer’s yeast (10%), lucerne (8%) |
| Net feed conversion ratio | 3.61 (carrots excluded) |
| Minimum feed conversion ratio | 2.2 |
| Average FCR in cattle | 8.52 |
Characteristics That Make Mealworms Suitable for Livestock Feed
Mealworms are packed with nutrients. They contain 48% protein, which is almost as high as soy, and they provide more energy per pound. Their ash and crude fiber content are lower than soy, making them easier for livestock to digest. This means your animals get more nutrition from every bite.
| Characteristic | Mealworms | Soy |
|---|---|---|
| Protein Content | 48% | 50% |
| Total Energy per Pound | Higher | Lower |
| Ash Content | Lower | Higher |
| Crude Fiber Content | Lower | Higher |
Another great thing about mealworms is their sustainability. They need less than half a gallon of water per pound produced, which is 500 times less than soy. They can also be fed on biowaste, which not only enriches their nutritional profile but also helps manage waste. Plus, they grow well in confined spaces, reducing their carbon footprint. These traits make natural dry mealworms an eco-friendly and efficient choice for livestock feed.

Switching to natural dry mealworms as livestock feed can save a surprising amount of resources. Mealworms require significantly less land, water, and energy compared to traditional feed sources like soy or fishmeal. For example, mealworm production uses only 43% of the land needed for milk and a mere 10% of what beef requires. This makes them an excellent choice for farmers looking to reduce their environmental footprint.
| Resource Type | Mealworms | Milk | Chicken | Pork | Beef |
|---|---|---|---|---|---|
| Land Use (LU) | Very low (1.81–3.23× lower) | 1.81–3.23× higher | 2.30–2.85× higher | 2.57–3.49× higher | 7.89–14.12× higher |
| Fossil Energy Use (EU) | 21–83% of milk | 21–83% higher | 46–88% higher | 55–137% higher | 1.02–1.58× higher |
Mealworms also consume less water and energy during production, making them a sustainable alternative to conventional feeds. By choosing mealworms, you’re not just feeding your livestock—you’re conserving vital resources.
Lower Carbon Footprint
Natural dry mealworms have a much smaller carbon footprint compared to other feed sources. Their production emits fewer greenhouse gases (GHGs) and uses less non-renewable energy. In fact, mealworms produce 23% fewer GHG emissions and use 18% less non-renewable energy than broilers. They also occupy 70% less agricultural land, which helps combat deforestation and habitat loss.
