Feed contamination is often a major contributor to feeding losses and failures. Therefore, when using feed, it is necessary to guard against the following six kinds of pollution: Insect pests and pests can cause loss of feed nutrients or leave toxins in the feed. In the case of suitable temperature and high humidity, mites are more harmful to feed. Rodent damage not only causes loss of feed, but also causes feed pollution and spreads diseases. Microbial contaminated feeds breed harmful microorganisms such as Aspergillus flavus, Gibberella and Fusarium, which produce aflatoxins, gibberellins, gibberellins and other toxins harmful to livestock and poultry. Among them, aflatoxin is the most toxic. The anti-nutritional factors in the anti-nutritional factor-contaminated feed mainly include protease inhibitors, carbohydrate inhibitors, mineral element bioavailability inhibitors, antagonistic vitamin action factors, and stimulating animal immune system action factors. Their presence can interfere with the digestion, absorption and utilization of feed nutrients by livestock and poultry. Harmful chemical substances mainly include three types of harmful chemical substances such as pesticide pollution, industrial “three wastes†pollution, and nutritive mineral additive pollution. Non-nutritive additives contaminate antibiotics, hormones, antioxidants, anti-fungal agents and sedatives, which have a great effect on preventing diseases, improving feed utilization and growth rate, but if you do not strictly follow the principle of use and control the use of safe dosage and stop At the time of the drug, the drug and its metabolites will remain in the meat, eggs, and milk, and will pollute the environment through livestock waste. The process of poison cross-contamination produced during processing is improperly controlled. The complex additives in the feed will undergo degradation reactions, redox reactions, etc. during special processing such as crushing, conveying, mixing, granulating, and puffing, resulting in some complicated Compound. In addition, contaminant contamination in feed production is also an important factor affecting feed hygiene and quality. Therefore, in the process of feed processing, care should be taken to clean the equipment to avoid decomposition and residue of the feed during transportation and mixing.
