During the storage, transportation, sale, and use of feed, it is highly susceptible to mold contamination. The growth and reproduction of mold not only consume essential nutrients in the feed but also significantly reduce its quality, leading to lower feed efficiency. Moldy feed can cause digestive issues such as diarrhea and enteritis, weaken the immune system, and even result in serious health problems or death in animals. Because of this, feed manufacturers and researchers around the world have placed great emphasis on developing and applying anti-mold technologies. In recent years, several effective anti-mold techniques have been widely used abroad.
1. **Radiation Sterilization**
After processing feed into powder or pellets, it may become contaminated with harmful bacteria like Salmonella and E. coli. American researchers tested the effects of gamma radiation by exposing chicken feed to 10 kGy of gamma rays. When stored at 30°C and 80% humidity for a month, the irradiated feed remained free from mold, while non-irradiated feed became moldy within days. This method effectively sterilizes the feed and allows long-term storage without spoilage.
2. **Adding Mold Inhibitors**
Many countries use various mold inhibitors, including potassium iodide, calcium iodate, calcium propionate, formic acid, seaweed powder, and citrus peel extracts. Japanese scientists found that combining these agents yields better results. A mixture of 92% seaweed powder with 4% calcium iodate and 4% calcium propionate, added at 8% of the feed weight, prevented mold growth for over a month under high humidity. In contrast, untreated feed became moldy within five days. This combination has led to the development of highly effective mold inhibitors.
3. **Mold-Proof Packaging Bags**
Japanese researchers developed a special packaging bag that prevents mold for extended periods. These bags are made from polyolefin resin containing 0.01% to 0.50% vanillin or ethyl vanillin. The resin slowly releases the compound, which penetrates the feed to inhibit mold growth while adding a pleasant aroma that improves palatability. An outer film prevents the loss of the active ingredient, ensuring long-lasting protection.
4. **Combining Chemical Disinfection and Radiation**
Soviet researchers found that combining chemical treatment with radiation enhances both sterilization and mold prevention. They treated feed with ammonia, propionic acid, or formic acid before exposing it to ultraviolet light. This dual approach reduced microbial growth by 99.8% and increased vitamin D content to 180 mg/kg, outperforming either method alone.
5. **Controlling Fungal Genetics**
Mold in feed is often caused by fungi like Aspergillus, which produce harmful aflatoxins. Scientists have genetically modified these fungi to eliminate their ability to produce aflatoxin. These modified strains can outcompete wild molds, reducing contamination and improving feed safety.
In conclusion, the development and application of these anti-mold technologies are crucial for maintaining feed quality and animal health. As global demand for safe and nutritious feed increases, continuous innovation in this field remains essential.
