The principle of prevention and treatment of pork mold infection and toxin poisoning

1.1 Name

The reason why pork mold infection and toxin poisoning named the disease name of mold and its toxins on the disease after the pork group became "pig mold infection and toxin poisoning" was due to the "diet" of pigs who had not heated.In the "diet" and related diseases with high toxin content, during the diagnosis of pig diseases for such diseased pigs, it was found that in addition to the cause of mold toxin poisoning, the diseased pigs were found.Therefore, molds and toxins that exist in the diseased pig tissue organs are commonly used to the pig body, causing their onset.At least 28 kinds of breeding links caused by pork groups and toxin poisoning.Moobe is a major type of microorganisms with certain common characteristics. A fungi is a single -cell or multi -cell heterotrophic nucleus, with non -photocominic pigment. The cell wall contains a few chips and cellulose.There are many types, and about 100,000 species have been found.Mold is a fungus that can form a mycelium. In essence, molds belong to the sub -gates of the fungal door in classification, not a term of classification, that is, all the silk fungus can be called it. They are various plants from various plantsThe environment -related stress response or changes in the growth conditions of mold growth.

1.2 Harm

The cause of pork mold infection and toxin poisoning may come from a variety of different breeding links. Among them, feed source factors have attracted the most attention of the industry, such as Xu Guodong [3].The pollution status of toxin found that: 8 samples totaling 43,492 parts of the samples were tested, namely vomiting toxins (DON), corn gobrotone (Zen), machinic toxin B (AFB), T-T-2. Fuma toxin B1 (FB1), 赭 mold toxin (OTA).② The total detection rate of 6 kinds of mold toxins is 67.96%to 67.99%. The total detection rate of different sample toxins is higher than 50%. The types of toxins contaminated by different samples are different.It is DON, FB1, Zen, T-2 and AFB.It can be seen that the content of mold toxins in domestic feed and their raw materials is generally high.

After the occurrence of pork mold infection and toxin poisoning, it can lead to clinical symptoms. There are three main types of mold in the production of animal husbandry: Estaline, Sydromae, and green mold.In 1988 and 1989, it was found that DON toxins in T-2 and HT-2 toxins (crescent toxins) were found in the test of feed or feed raw materials from all walks of life.

Different molds are different.

Eylum poisoning can cause symptoms such as slow growth of animal growth, decreased egg production, and fatty liver.Poisoning of sickle bacteria can cause animal vomiting, lesions, abortion, central nervous disorders (T-2), lesions, refusal, etc.The symptoms of rectal cutting out, decreased pregnancy rate, and decreased semen quality.

Poisonous poisoning can cause symptoms such as slow animal weight gain, damage to liver function and renal function, pig nephritis, and acute nephritis.Unknowingly caused animal diseases to be unknown, pig mold toxins can cause sows to reduce eating and insufficient milk.The rate is not ideal. The sow can have less available years, high elimination rate, scarcity of boar sperm, and loss of losses with unlimited number of babies.Therefore, we must pay attention to the role of mold toxins in production, and add fungal toxin adsorbent to the feed to reduce the chance of other diseases.

The reasons for pigs in the pigs to breed pork and toxin poisoning are from four aspects, that is, there are four sources: air, water, feed, and pharmaceutical source.

2.1 Air source factors

Due to the cold climate, the humidity of the pig house is too large, and the lapse of the circle house is poor. The walls of the pig house, the window sills and railings of the circle, and the environment have a large amount of mold growth.As the temperature rises and the air flows, these mold spores and mold toxins will be attached to the air in the house. Pigs only inhale spores and toxins through the respiratory tract, or the spores and toxins that fall into the full -cost material through the digestive tract intakeThe long -term accumulation caused the disease to the pork group.

2.2 Water source factors

The pig’s drinking heater has accumulated pollutants such as crickets and sediment for a long time, and is cleaned up, rinsed, and disinfected from time to time;

2.3 Feed source factors

In addition to Xu Guodong et al., In addition to the feed and raw reasons that have been reported in Xu Guodong, feeding of mildew wheat bran, rice bran, tofu, peanut cake and other feeding can also cause the pork group to become ill.

2.4 Pharmaceutical factors

In addition to antibiotic drug poisoning, the most important thing to pay attention to is the reality of the allegedness of mold and its toxins in the veterinary drugs.

3.1 Four causes of removing mold infections and toxin poisoning

During the breeding process, we must follow the concept of "infinite amount of mold toxins" to ensure the combination of thermal insulation and ventilation in the pig house and just right, to ensure the quality and safety of water sources. The water heater and grooves should be regularly cleaned and disinfected.The selection of feed should ensure the quality of additives and feed raw materials, and ensure that the low -priced feed in pig feed low -mold content and low -mold toxin content, not in use or use long -term placed medium herbs, so as to avoid and avoid mold infection as much as possible.The occurrence of toxin poisoning in the pig group is the most practical and economic method for preventing and treating such diseases, because even some mold toxins that have been heated at high temperature may still have biological toxicity.

3.2 Drugs or additives can fight mold and its toxins

The use of drugs flowing in the market can fight against mold and its toxins, which can effectively reduce the harm of mold and its toxins to pigs.The technologies for reducing reduction include 5 categories, namely physical laws (over screening, peeling, radiation), adsorption method (silicon aluminate, glycotic sugar, activated carbon, sodium humic acid), biological method (survival competition (survival competition competitionMicrobial, production reduction enzyme microorganisms), functional nutrients (functional amino acids, composite antibacterial peptides), Chinese herbal medicine method, and multiple reduction technical hybrid methods. Some of these technologies are in the research stage and some have been applied to production practice, butThere are more or less defects, which are determined by the effective component characteristics of various types of confrontation drugs or additives.

During the pig breeding process, pig mold infections and its toxin poisoning will always bother farmers. The loss caused or potential to cause or potential is inestimable.These drugs or additives believe that "everything is good". It is necessary to combine the actual situation of the field, carefully compare the above four categories of pathogenic sources, and constantly reflect on the details of production.The purpose of the purpose of reducing reduction of the application, which is possible to minimize the economic losses caused by this type of disease.
