What should be paid attention to rosin-fed yellow mealworms?

What should you consider when feeding yellow mealworms with rosin? Tenebrio molitor, or yellow mealworms, have a broad diet and can be raised on agricultural by-products, livestock manure, and even wine lees. These materials can be processed using a fermentation system like the Ginba Fermenter to create high-quality feed. However, when using certain by-products such as rosin or wine lees, there are some important factors to keep in mind. One of the key concerns is the acidity of the material. Rosin, for example, contains various organic and inorganic acids, which can lower the pH significantly. Before using these materials in the fermentation process, it's essential to adjust the pH to around 7-8 using lime. This is similar to the ideal pH range for other fermentation processes, such as those used in goldfish feed, where a slightly alkaline environment promotes better microbial activity. Additionally, when selecting raw materials, avoid any that are already spoiled, smelly, or have an unpleasant odor. These could introduce harmful bacteria or toxins into the feed. If using straw or other fibrous materials, make sure they are properly crushed to improve digestibility and mixing. It's also a good idea to combine several types of raw materials to create a more balanced and nutritious feed. When introducing new feed sources, it's best to start with small amounts and gradually increase the proportion over time. Never replace the existing feed abruptly, as this can cause digestive issues in the mealworms. Following a gradual transition helps maintain their health and ensures a smooth adaptation to the new diet.
