Feed Mold Prevention and Detoxification
Proper storage is essential to prevent mold growth in animal feed. First, ensure the storage area is dry, clean, and well-ventilated. Place the feed on a raised platform with enough space around it to allow air circulation. This helps reduce moisture buildup and prevents mold from developing.
During the rainy season, consider using sealed plastic bags to store feed. This method creates a low-oxygen environment that inhibits mold growth. Another option is to use a mixture of acetic acid and sodium acetate—combine 2 parts acetic acid with 1 part sodium acetate, add 1% sorbitol, mix thoroughly, and dry the solution. Then, mix it into the feed at a rate of 1%. This treatment can keep the feed mold-free for over 90 days.
Calcium propionate or sodium propionate can also be used as mold inhibitors. Add 50 grams of sodium propionate or 100 grams of calcium propionate per 100 kilograms of feed. Mix well and store in wooden barrels, cement tanks, or plastic bags. This method ensures the feed remains mold-free for more than 100 days.
Another effective solution is to use a mildew-prevention agent. Add 500 grams of the agent per ton of feed to prevent clumping and mold for up to 60 days.
Good feeding management is also crucial. Avoid overfeeding and ensure feed is stored in small quantities to prevent spoilage. Regularly check for clumping and remove any damp or spoiled portions. Clean and disinfect feeders and water troughs regularly to maintain hygiene. Turn the feed occasionally to prevent moisture accumulation and mold growth.
If mold does occur, there are several detoxification methods available. One approach is washing: place slightly moldy feed in a tank, add fresh water (preferably boiling), and stir with a wooden stick. Rinse the feed 5–6 times until clean. It can then be safely fed to livestock.
Cooking is another effective method. Boil the moldy feed in water for 30 minutes or steam it for an hour. After removing the water, it can be used for feeding.
Lime water soaking is also useful. Soak the moldy feed in 10% pure lime water for three days, then rinse with clean water and dry before use.
Ammonia treatment involves adjusting the moisture content of the feed to 15%, placing it in a container, adding ammonia, and sealing it for 12–15 days. After drying, the ammonia levels will decrease, making it safe for consumption.
Lastly, the sucrose detoxification method involves soaking the moldy feed in a 1% sucrose solution for 10–14 hours. Remove the solution, rinse with water, and dry the feed before using it.
By following these prevention and detoxification methods, you can significantly reduce the risk of mold in animal feed, ensuring the health and safety of your livestock.
