The main effect of mycotoxin is that the toxin will cause immunosuppression in pigs, resulting in low immunity in pigs. Farmers often find this situation. The vaccine was obviously made, but it didn't work, which was probably caused by immunosuppression. The vaccine is injected into the pig which is essentially a weak virus, and with the help of the pig's own immune system, antibodies are produced to resist foreign wild viruses. Pigs eat feed contaminated by mycotoxin, and their immune function is suppressed. Even if they are vaccinated, nothing will happen.
Hazards of mycotoxins:
Aflatoxin: growth retardation, decreased feeding rate, roughness, depression, anorexia, acute liver disease and immunosuppression.
Ochratoxin: attacks the kidney, immune and hematopoietic systems, making the liver fragile, reducing weight gain and growth retardation.
Vomiting toxin: it damages the intestine, reduces food intake, and is susceptible to secondary bacterial infection, vomiting and refusal to eat.
T-2 toxin: invading digestive tract, stomach and intestinal diseases, reducing eating, refusing to eat, vomiting and immunosuppression.
Citrinin: invades the kidney, causing renal pathological changes, decreased food intake, polyuria, soft stool and diarrhea.
F-2 toxin: Estrogen is overactive, estrus is irregular, abortion and stillbirth occur, and the semen quality of boars decreases.
Fumonisins: growth retardation, jaundice, chronic liver dysfunction, decreased food intake and immunosuppression. Sows cause abortion, the semen quality of eight-legged pigs decreases, the growth rate slows down, the feed intake rate decreases, sow wigs fall in love, and abortion occurs.
