Precautions for storing feed
High temperatures and high humidity during storage are the primary causes of mold growth in animal feed. These conditions not only activate enzymes like lipase, amylase, and protease, which accelerate the breakdown of nutrients in the feed, but also create an ideal environment for harmful microorganisms and pests to multiply rapidly. This leads to the accumulation of heat and moisture, resulting in fermentation and mold formation. To prevent this, it's essential to maintain a relative humidity below 70% and ensure that the moisture content of the feed does not exceed 12.5%. Proper storage conditions play a crucial role in maintaining feed quality and safety.
Preventing mold and bacterial growth is vital to avoid spoilage and deterioration. Mold not only degrades the nutritional value of the feed but can also lead to health issues in livestock, such as digestive problems, diarrhea, and even severe cases of enteritis. In some instances, it may result in significant economic losses due to reduced productivity or animal mortality. Therefore, it's important to implement effective measures to control mold, such as using natural or chemical preservatives, ensuring proper ventilation, and maintaining clean storage areas.
Mold is a common issue during the entire lifecycle of feed, from storage and transportation to sale and use. The presence of large amounts of mold reduces the feed's quality and market value. It also poses serious risks to the health of animals consuming it. Studies have shown that in addition to improving storage conditions, the most effective method to extend the shelf life of feed is to apply physical or chemical anti-mold treatments, such as adding mold inhibitors directly to the feed.
In summary, compound feed should be stored in cool, dry, dark, and clean environments. Granulated compound feed typically has a shelf life of 1–3 months, while powdered compound feed should be used within 10 days. The storage duration for powdered concentrate and premix feeds varies depending on the amount of antioxidants added—usually between 3–4 weeks and 3–6 months. Following these guidelines helps maintain the quality and safety of feed, ensuring better outcomes for both producers and consumers.
