1. Mildew of feed raw materials or feed products The air humidity in the southern region is relatively high, especially in the rainy season every year, improper moisture-proof measures in the feed raw material warehouse can easily cause mildew of the feed raw materials. If moldy raw materials are used to produce feed products, the mycotoxins in the feed products are likely to exceed the limit. Even if the feed products are produced with non-mold raw materials, if they are stored for too long or are soaked by rainwater during transportation, they will cause mildew in the feed.
2. The impact of environmental pollution on feed materials In some areas, due to industrial pollution and excessive use of pesticides and fertilizers in agricultural production, the content of heavy metals in soil or groundwater exceeds the standard or contains other toxic and harmful compounds. The heavy metals in feed materials grown from these soils Or other toxic and harmful substances will also pose a great threat to feed safety and food safety.
3. Insufficient or excessive addition of mineral trace elements From a nutritional point of view, an appropriate amount of mineral trace elements can promote the growth and development of animals, but it is not the more the better. If the added trace elements exceed the allowable addition range, the It may cause animal poisoning or physical discomfort, otherwise it will cause animal malnutrition. In order to meet the needs of some customers, some feed manufacturers add excessive trace elements to the feed. Long-term feeding of feeds containing excess trace elements will cause the heavy metal content in some animals to exceed the standard, which not only affects the quality and safety of animal products, but also pollutes the environment.
4. The application of illegally adding functional feed additives in the banned drug market is becoming more and more common. Some functional feed additives such as microorganisms, enzyme preparations, plant extracts, and polysaccharides are claimed to have the effect of replacing "antibiotics", and there is the possibility of illegally adding prohibited substances to these alternative products. If a functional feed additive containing illegally added prohibited substances is used to produce commercial feed, the commercial feed will also contain prohibited substances.
