Why More Mycotoxin Liver Occur When The Price Of Feed Raw Materials Rises?

Due to the sharp decline in the number of grain exports caused by the Russian Ukrainian war and the speculation about the decline of soybean storage, there was a shortage of feed raw materials, which formed a strong support for the rise of raw material prices. In this case, feed enterprises reduce the purchase standards of raw materials and inevitably use some feed raw materials such as corn, wheat, peanuts and soybeans polluted by mycotoxins.

The investigation shows that the detection rate of aflatoxin in poultry feed is 100%, and the over standard rate is as high as 28.57%, indicating that the mycotoxin pollution in poultry feed is still very serious.

Mycotoxins are widespread, such as grain growth, harvesting, storage and on-site feeding management.

Mycotoxin is also very harmful to poultry. Its main manifestations are as follows:

1.??Mycotoxin Burns The Digestive Tract, Causing Intestinal Absorption Disorder

Mycotoxin will cause serious damage to the digestive tract of poultry. The most obvious damages are crop inflammation, muscle stomach crack and erosion. Due to the destruction of crop and muscle gland stomach, the feed cannot be fully infiltrated and worn to a small enough particle size to reach the intestine. Over time, it will cause intestinal absorption disorder, yellow and black loose stool and high feed meat ratio(FCr).

2.?Mycotoxin Damages Poultry Liver And Causes Mycotoxin Liver

Eating feed that contains?excessive mycotoxin?for a long time will lead to the mycotoxin liver. Through anatomy, it is found that poultry have symptoms such as hepatomegaly, blackening, flower liver and liver necrosis, which is due to the degeneration and necrosis of hepatocytes and proliferation of hepatic tubules caused by mycotoxin.?Acute poisoning showed jaundice, hemolytic jaundice, liver dysfunction and elevated serum glutamate alanine aminotransferase;?Chronic poisoning is characterized by cirrhosis, ascites, anemia, decreased production performance and so on.

3. Mycotoxin Damages Poultry Reproductive System

For laying hens or breeders, it will also cause ovarian and fallopian tube atrophy, decrease egg production, and increase abnormal eggs such as blood spotted eggs, sand shell eggs, thin shell and soft skin eggs. In addition, mycotoxin can also lead to abnormal testis and spermatogenesis of breeding cocks, resulting in many problems such as low hatching rate of chicks.

4.Mycotoxin Destroys Poultry Immune System

Mycotoxins can also damage the immune system of poultry, such as the destruction of organs and immune organs such as lymphatic system, liver and spleen, which is very easy to cause immunosuppressive diseases in poultry. Once immunosuppression occurs, poultry are vulnerable to bacterial and viral attacks when subjected to external stress, resulting in mixed infection diseases such as gasbag inflammation and serositis.

Adding bile acid to poultry feed is one of the effective means to reduce the harm of mycotoxin. After chelating with intestinal endotoxin, bile acid can make mycotoxin molecules larger and hinder them from entering the blood circulation. Deoxycholic acid in bile acid can effectively decompose mycotoxin, making mycotoxin become water-soluble and then decompose. The addition of bile acids can also promote hepatocytes to secrete a large amount of thin bile, unblock the bile duct, eliminate bile stasis, play a cholagogic role, and excrete various toxins through feces, so as to maintain animal health.
