1. Look at storage conditions
Regardless of the season, when the relative humidity of the warehouse is between 80% and 100%, molds will grow rapidly. At this time, the storage of feed is prone to mold deterioration, and mold inhibitors must be used. However, the dosage should be flexibly controlled according to environmental conditions; if the relative humidity in the warehouse can be controlled below 70%, it can be stored for a long time without mildew without using anti-mold agents. Under normal circumstances, the higher the temperature, the greater the humidity, and the longer the storage time, the more it is necessary to use an anti-mold agent.
2. Look at the pH of the feed
The different mineral elements contained in the feed determine that the feed is physiologically acidic and physiologically alkaline. Most green feeds, beans and potatoes are alkaline, while grains and peanuts are acidic. Common feed anti-mold agents have a suitable pH range. When choosing an anti-mold agent, attention should be paid to the pH of the feed. If the pH of the feed exceeds the appropriate range of the anti-mold agent, it will be difficult to exert its inhibitory effect on mold.
3. look at the feed moisture content
If the feed moisture content is below 11%, it is not necessary to use an antifungal agent; if it exceeds 13% and needs to be stored for more than two weeks, use an antifungal agent; if long-term storage is required, the moisture content should be less than 14%.
4.look at feed ingredients
For feeds with high fat content, the use of organic acid fungicides is better, because fat can improve the penetration of organic acids and enhance the antibacterial effect; while for feeds with high protein content, the use of organic acid fungicides is not effective , Because the buffering effect of protein can neutralize organic acids.
5. look at the feed formulation
Animal feeds are more prone to mold deterioration than plant feeds, and powdered feeds are more likely to be moldy than raw pellets. Special attention should be paid to the use of antifungal agents during storage, and the dosage should be appropriately increased. The finished pellet feed kills some microorganisms during the processing process and is not easy to mold. However, under the conditions of high temperature and high humidity, an anti-mold agent is also required. Feeds stored in anti-mold packaging bags do not require additional anti-mold agents. Bulk feed and feed processed and prepared by farmers are most susceptible to mold contamination and should not be stored for too long. In summer and autumn, special attention should be paid to prevent mold deterioration. Chicken feed is more susceptible to mildew than pig feed, so care should be taken when storing it.
6. look at the characteristics of varieties
When choosing a suitable antifungal agent, the characteristics of the antifungal agent must be considered comprehensively. Combine two or more antifungal agents to form a compound antifungal agent. The compound anti-mold agent has a wide antibacterial spectrum, good effect, small dosage and a wide range of applications.
