Aflatoxicosis (Aflatoxicosis) is primarily an injury to the liver of animals, injured individuals depending on the age of the animal species, gender and nutritional status. Studies have shown that aflatoxins can lead to decreased liver function, reduced milk production and egg production. It also reduces the animal's immunity to infection by harmful microorganisms. In addition, long-term consumption of feed containing low concentrations of aflatoxins can lead to intra-embryonic toxicity. Young animals are usually more sensitive to aflatoxins. Clinical manifestations of aflatoxins are digestive disorders, reduced fertility. Reduced feed utilization, anemia, etc. Aflatoxins not only reduce milk production in dairy cows but also cause milk to contain transformed aflatoxins M1 and M2. According to U.S. agricultural economists, the consumption of aflatoxin-contaminated feed causes at least 10% of the U.S. livestock industry's economic losses each year. In China, the resulting losses to the livestock industry could be even greater. Aflatoxin can cause atrophy of the bursa and thymus, subcutaneous hemorrhage, poor response, decreased resistance, vaccine failure, increased susceptibility to disease, smaller eggs, lower yolk weight, lower fertilization rate, hatchability, increased embryonic mortality and unhealthy, in poultry. It also causes slow growth, decreased feed rate, jaundice, rough coat, hypoproteinemia, hepatocellular carcinoma and immunosuppression in livestock.
