The harm of mycotoxin to poultry in summer

Mycotoxin, a toxic fungus that occurs mostly in the summer, provides the best place for pathogens to breed and breed in high temperatures and humidity. Poultry can be infected by ingesting or inhaling pathogens. The age of 1 month, especially the age of 5-9 days, is the most susceptible to infection.

Mycotoxins are highly corrosive and cause severe damage to the digestive tract. It can cause oral ulcer, crop inflammation and pseudomembrane, ulcerous and hyperplastic myoglandular gastritis in the late stage of the disease, corneal thickening and the formation of bleeding ulcer under the cornea, increased intestinal fragility, intestinal mucosa off, necrosis. Affect the digestion and absorption of nutrients, feed utilization and conversion rate decreased. It can also cause atrophy of immune organs such as bursa of fabricius, thymus and spleen and induce immunosuppression. Common mycotoxins include Aspergillus flavus, vomitus mould, Aspergillus fumigatus, ochratoxin, etc. :

Vomit mold mold toxin can cause regular diarrhea, intestinal disease is not cured for a long time, feed will occur frequently, feed intake greatly reduced, weight loss significantly.

Aflatoxin intoxication can lead to multifocal necrosis of hepatocytes, proliferation of hepatocytes, and the appearance of dark red due to congestion in the early stage and yellow due to fat accumulation in the late stage of the disease, but whether the onset of early and late are the feeling of rubber liver.

The gallbladder mucosa is inflamed due to the proliferation and necrosis of the bile ducts, resulting in an increase in gallbladder fragility. Zearalenone mycotoxin could decrease the egg production, egg shell quality, fertilization rate and hatching rate of breeder chickens.

The renal damage caused by ochratoxin is characterized by degeneration and obstruction of renal tubules, resulting in urate deposition, which leads to the occurrence of gout and an increase in leg disease of unknown etiology. Aspergillus fumigatus can cause ophthalmia, dermatitis, necrotizing granulomatous dermatitis.
