Fermented feed raises the nutritional content of yellow mealworms
As Tenebrio farming grows into a major industry, the focus on feed sources and nutritional value has become increasingly important. Traditionally, farmers have relied on simple feed formulas, but this approach can lead to problems over time. Using single-component feeds not only affects the growth and reproduction of mealworms, but also reduces their overall nutritional value and taste—factors that significantly influence the quality of meat from chickens and pigs raised on such feed. Just as naturally raised animals differ in flavor and price from those fed commercial diets, mealworms are no different. The more diverse and balanced the feed, the better the final product.
Wheat bran, rice bran, and corn have long been the standard for feeding mealworms, but their nutritional profiles are limited. In reality, mealworms are omnivorous and can thrive on a variety of materials, provided they contain the necessary nutrients and are in a suitable form. For example, crop residues, sawdust, cottonseed hulls, bagasse, livestock manure, mushroom cultivation substrates, and brewing byproducts can all be used as feed sources. However, these materials often suffer from poor palatability and texture, making them unappealing to mealworms. To overcome this challenge, fermentation is essential.
Fermentation improves both the physical properties and aroma of the feed, making it more appealing to mealworms. By combining chicken manure with straw, sawdust, and other organic matter, and using a specialized microbial fermentation agent, farmers can create a highly nutritious and cost-effective feed for Tenebrio molitor. This process not only enhances the appearance, smell, and texture of the feed, but also greatly improves its nutritional content. Compared to traditional methods, this approach saves up to 70% of labor time. For instance, Jinbao Type II Fermentation Additives can complete the process in just two days, while other types may take three to five days. Additionally, the cost per kilogram of the additive is only a few cents, making it an economical choice.
The use of high-quality microbial starters is crucial for success. These biological agents are developed through advanced scientific techniques, including controlled cultivation, purification, and rejuvenation. They contain key microorganisms such as bacteria, fungi, yeast, and actinomycetes, which play a vital role in breaking down organic waste into usable feed or fertilizer. This not only helps reduce waste but also turns it into a valuable resource, improving sustainability and lowering costs in aquaculture and agriculture.
After special fermentation, the protein content and palatability of the feed improve significantly, leading to higher feed intake by mealworms and better economic returns. This innovative approach is gaining popularity among farmers due to its efficiency, environmental benefits, and profitability. It's a win-win solution that aligns with modern agricultural practices and supports the growth of the Tenebrio farming industry.
