For example, aflatoxin can not only reduce the milk yield of dairy cows, but also make milk contain transformed aflatoxin. Aflatoxin B 1 is an important cause of human liver cancer.
Eating pigs can cause aflatoxin poisoning, commonly known as "yellow fat pig". Piglets and pregnant sows are more sensitive. Poisoned piglets often have acute attacks, central nervous system symptoms, head bending to one side, angular arch extending backward, and die within a few days. Big pigs have a long course of disease, listlessness, loss of appetite or abandonment, thirst and excessive drinking; Visible mucosa yellow or pale, skin congestion and redness or bleeding spots; Limb weakness, stumbling; The feces are dried first and then diluted, and in severe cases, they are mixed with bloodshot and even bloody dysentery; The urine is yellow or tawny and turbid. In the later stage, sick pigs have mental symptoms such as intermittent convulsions and varus cornus, and most of them die of exhaustion. Chronic poisoning pigs have normal body temperature, loss of appetite or disappearance, or only eat green feed without feed, with slightly yellow or pale mucosa and normal skin. However, the internal organs have been damaged by toxins, which often aggravate the condition and even lead to unexplained death when stimulated. In the practice of raising pigs, the harm of moldy corn is not like the severe infectious diseases such as swine fever and blue ear disease, where pigs suddenly get sick and die in large numbers. His injury is potential, or accumulated bit by bit. His appearance may be normal, but he may get sick immediately after being affected by external pressure. For example, the rate of sow abortion and estrus mating is poor, and vulva enlargement occurs in reserve sows and fattening pigs. The most terrible thing is that it can reduce the immunity of pigs (that is, what we call immunosuppression), resulting in poor immune effect of vaccines and increasing the sensitivity of pigs to various diseases.
Treatment measures of moldy feed
Feed with serious mildew must be discarded and must never be used to feed livestock and poultry. However, if all the mildewed feed is discarded, it will cause great economic losses. Therefore, according to the different conditions of feed raw materials and products, the slightly mildewed feed should be detoxified.
Sunbathing: Sunbathing is a commonly used detoxification method. The moldy feed is dried in the sun, and after a period of time, it is stored in a ventilated and dry place. It mainly uses the characteristics of different wavelengths of sunlight to achieve the purpose of detoxification. This method has a good effect on removing mold spores and their toxins. However, the mycelium produced by mold can not be removed. Therefore, the feed treated in this way does not eliminate the musty smell, so it will affect the palatability.
Drug mildew removal method: However, although this mildew removal method will reduce mildew, it will cause residue and cannot be completely removed.
Mechanical precision mildew removal method: a kind of equipment specially used for feed enterprises and large-scale farmers to remove corn mildew. The principle of use is to use the principle of sand roller friction cutting to remove the moldy skin of moldy corn, especially the moldy germ part. This machine can not only solve the problem of mildew, but also prevent corn from mildew during storage, which is a long-term benefit of investment. At present, it is a mildew removal method agreed by large feed enterprises and large aquaculture households.
The corn mildew-proof equipment developed by Lushan Huayu Wantong in cooperation with domestic feed enterprises is suitable for polishing the surface of corn grain with mild or moderate mildew before or after drying the raw grain purchased by large, medium and small grain storage enterprises. After the corn with serious mildew is polished, if some mildew spots are immersed in the corn epidermis, a color sorter is needed to remove the seriously moldy particles. Reduce the purchase quantity of color sorter, reduce the equipment cost and improve the economic benefit. Improve the grade of corn, and increase enterprise and social benefits. Improve the grade of corn to meet the quality requirements of purchasing and storage companies. Our company can configure the mobile operation trolley according to the customer's demand, which is convenient for customers to use, improve the equipment under various industrial and mining conditions and effectively improve the equipment utilization rate.
Suitable for enterprises with drying towers. When wet grain is dried, mold adheres to the surface of mild and moderate corn, and the surface is polished with this machine. You can buy slightly mildewed grain at a low price, and after grinding, you can reach the standard of commodity grain, get high profits, and make outstanding contributions to food security in this region.
Suitable for self-employed, rural mobile operations (both motors and diesel engines can be used) to polish the incoming materials, get a processing fee of about one ton of 30 yuan, and at the same time solve the urgent needs of farmers and large grain growers to achieve a win-win goal. It is of great significance to ensure food safety (the machine consumes about 2 kWh of electricity per ton of material).
