Pig disease more - pay attention to the harm of mycotoxins

Due to the increase of the global greenhouse effect, the degree and extent of contamination of food or feed by mold and its toxins have become increasingly apparent. According to statistics, 25% of the world's grains are contaminated with mycotoxins every year. In addition to the direct killing of livestock and poultry by mycotoxins, the more important thing is to reduce the immune function and production performance of livestock and poultry, and remain in a sub-health state for a long time, resulting in many immune failures and diseases that frequently occur and are difficult to prevent.

Mycotoxins are toxic secondary metabolites produced during the growth and reproduction of mold-producing fungi on grain or feed. So far, more than 350 mycotoxins have been detected, and dozens of them are known to cause harm to humans and animals. At present, the infection rate of mold in feed in China is close to 100%, and the amount of bacteria that exceeds the national standard is approximately 50%. There are mainly six toxins, namely aflatoxin, (AF), DON, T-2 toxin, and corn. Zearalenone (F2 toxin), fumonisin, ochratoxin, of which the greatest harm to pigs is aflatoxin, DON, zearalenone (F2 toxin). In China's feed, the detection rate of mycotoxin in the full-price feed was over 90%. The most serious contamination was vomitoxin, fumonisin and zearalenone.

First, the harm of mycotoxin harm to pigs

1. Initiation of disease can lead to acute or chronic poisoning, mainly to liver and kidney damage and intestinal bleeding, ascites, digestive dysfunction, neurological symptoms and skin lesions, but clinically unless a large number of acute poisoning toxins die, and The performance of reproductive disorders, miscarriage, etc., so many symptoms are generally not indicative and specific, it is difficult to confirm is due to mycotoxin poisoning caused by, while a slight or a small amount of clinical manifestations, after mycotoxin poisoning can easily be ignored.

2. Destruction of the immune system The mycotoxin's immunosuppression caused by damage to the animal's immune system is his most important and most important hazard. Many mycotoxins can directly destroy or reduce the structure and function of the immune system. This is in animal experiments and production. Has been fully confirmed. For example, some mycotoxins can atrophy the thymus, inhibit or reduce the activity of lymphocytes and macrophages, inhibit the function of antibodies and cytoplasmic products, and macrophages and phagocytes, resulting in humoral and cellular immune disorders, etc. Both can severely reduce the immune response function. In recent years, many livestock and poultry have a wide range of diseases and are difficult to control, or after a large number of vaccines used for immunization, antibodies still do not reach the desired titer or even immune failure, and they are closely related to mycotoxin poisoning. In the summer of 2006, there were serious "pig noname fever" in many places. According to reports, feed mycotoxin is one of the culprits in causing the disease.

3, reduce the feed quality directly caused by decreased appetite, it is reduced. It can cause 14~20% loss of single item of feed, up to 31.5%, at the same time interfere with the absorption of nutrients, resulting in digestive enzyme activity, thus reducing the feed conversion rate, resulting in increased feed consumption and reduced production performance.

So how do we prevent mycotoxin harm to the pigs?

First, we should use good raw materials such as corn, bran, and soybean meal. For corn, on the surface, we sometimes see no mold, which is only a superficial phenomenon. Some moldy outside can not see, one of the 1000 corn mold, it is already very serious. For the corn we buy, it is recommended to sieve through the screen (screening those dirt, impurities, etc.), because they will increase the digestive burden of the pig.

In addition, we should add good quality de-moulding agents in the feed, such as: mildew. Guangdong Tengjun Animal Pharmaceutical Co., Ltd. cooperated with experts from Illinois State University in the United States to develop a high-tech product that combined the use of “physical adsorption, chemical bonding, anti-mildew detoxification, and enhanced immunity” in four ways to jointly control mycotoxins. "Moderate Consumer Safety - I". It is not only a strong adsorbent for mycotoxins, but the extract of “Mushi Xiao An-I” has the functions of clearing heat, detoxifying, protecting the liver and strengthening the kidney, effectively improving the immune function of animals and improving the immune effect of vaccine injection. In addition to mildew and detoxification, it can quickly overcome the immunosuppression caused by mycotoxins and pathogens, promote the immune function and disease resistance of livestock and poultry, and improve the immune response and antibody titer. Its dosage is 1Kg/ton for prevention and 2-3Kg/ton for mildew.

Through the above measures, the overall health status of our pigs will be significantly improved, reducing the harm of immunosuppression to pigs.

With the improvement of living standards, snack foods have been deeply loved by the masses of the people. When you walk into the supermarket, you will see snacks such as preserved fruit, sour horns, potato chips, almonds, pistachios, fish fillets, dried meat, and spiced fried meat. Snack foods are gradually upgrading to become the daily necessities of the people. As the economy develops and the level of consumption increases, consumers' demand for the quantity and quality of snack foods continues to grow.

The whole body of the duck is not only high in nutritional value and delicious, but also the various parts of the duck are also very delicious. The nutritional value of the snack is very high, such as duck's paw, duck, duck neck, duck tongue, duck gizzard, etc., delicious coveted, aftertaste It is a casual food for all ages.
