1. Mycotoxins can cause atrophy of immune organs such as bursa, thymus and spleen, and induce immunosuppression. Cause Newcastle disease, influenza and other immune failure.
2, mycotoxins can cause frequent diarrhea, intestinal diseases can not be cured for a long time, feed will occur frequently, feed intake is greatly reduced, weight is greatly reduced.
3. Mycotoxins are extremely corrosive and cause serious damage to the digestive tract. It can cause oral ulcers, inflammation of the crop and pseudomembranes, ulcerative and hyperplastic adenitis in the later stages of the disease, forming ulcers at the junction of the glandular stomach and the muscle stomach, and the muscle stomach corneous membrane is easy to peel off. Thickening of the corneal membrane and the formation of bleeding ulcers under the corneal membrane, intestinal fragility increased, intestinal mucosa off, necrosis. Affect the body's digestion and absorption of nutrients, feed utilization and conversion rate decreased.
4, mycotoxin poisoning can lead to liver multifocal liver cell necrosis, liver cell hyperplasia and early onset of the disease due to congestion and dark red, late due to fat aggregation was yellow, but regardless of the early onset and late for rubber liver feeling. Gallbladder mucosa due to bile duct hyperplasia and necrosis and inflammation, the phenomenon of increased fragility of the gallbladder.
5, mycotoxins will cause the decline of egg production, egg shell quality decline, fertilization rate and hatching rate decline, hatching embryo death is more common; mycotoxins by reducing the synthesis and transport of liver yolk precursors and the impact of laying hens, feed intake decline and the unreasonable ratio of feed price is the delay of sexual maturity of hens.
6, mycotoxin damage to the kidney for renal tubular degeneration and obstruction, resulting in uric acid salt deposition, resulting in the occurrence of gout, unknown etiology of leg disease increased.
7, mycotoxin damage to the blood vessel wall to increase blood pressure, increase the burden on the heart, make ascites multiple.
