This is a special type of Deoiled Rice Bran which is developed after critical studies and research. The fact is that presence of Aflatoxin B1 in feed leads to poor quality of livestock which results into poor quality of milk, meat etc, hence more adverse on human beings by consumption of milk, meat etc.
Contents of Special Grade of De-Oiled Rice Bran (Aflatoxin Free) :-
Aflatoxin B1- Below 50PPB (Below 20PPB on special demand)
Fibre – Below 11%
Crude Protein – Above 15%
Sand Silica –Below 3%
IMPORTANCE OF AFLATOXIN IN LIVESTOCK HEALTH
Diet is the major way through which humans as well as animals are exposed to aflatoxins.
The adverse effects of aflatoxins on animal can be categorized into two general forms- Acute Toxicity, Chronic Toxicity. Acute toxicity is caused when large doses of aflatoxin are ingested. This is common in livestock. The principal target organ for aflatoxins is the liver. After the invasion of aflatoxins into the liver, lipids infiltrate hepatocytes and leads to necrosis or liver cell death. This is mainly because aflatoxin metabolites react negatively with different cell proteins, which leads to inhibition of carbohydrate and lipid metabolism and protein synthesis. In correlation with the decrease in liver function, there is a derangement of the blood clotting mechanism, icterus (jaundice), and a decrease in essential serum proteins synthesized by the liver. Other general signs of Aflatoxicosis are edema of the lower extremities, abdominal pain, and vomiting. This is due to long term exposure of moderate to low aflatoxin concentration. The symptoms include decrease in growth rate, lowered milk or egg production, and immuno suppression. There is some observed carcinogenecity, mainly related to aflatoxin B1. Liver damage is apparent due to the yellow color that is characteristic of jaundice, and the gall bladder becomes swollen. No animal species is resistant to the acute toxic effects of aflatoxins.
Aflatoxicosis has the same toxic effects in poultry as it does in mammals. A dose of 0.25 ppm in turkey pouts and ducklings impairs growth, and a dose of 1.5 ppm in broilers and 4 ppm in Japanese quail has a negative affect on growth. An increase in blood clotting time increases the susceptibility of the carcass to bruising even at doses below that to have an affect on growth. In poultry, aflatoxins impair the availability of bile salts, which decreases Vitamin D3 production. This causes a decrease in the absorption of fat-soluble vitamins. Aflatoxins also decrease the production of Vitamin A in the liver, and it has secondary effects such as decreased blood calcium levels, decreased bone strength, and a decreased tissue and serum tocopherol level. This decrease in tocopherol levels can lead to Vitamin A and E deficiencies.
