Effect of probiotics and anti-oxidants in reducing the risk of aflatoxicosis in poultry

Abstract

In the conditions of RNO-Alania the most effective way to protect grain from contamination with mycotoxins is to prevent their formation all the way from the field to the consumer. For this purpose it is necessary to apply the improved technologies of cultivation, treatment, storage, as well as partially to disinfect grain products during grain processing. In the course of the research the MPC excess in T-2-toxin and ochratoxin A concentration in the selected samples of corn, barley and soybeans was not found. At the same time, the content of aflatoxin B 1 in the composition of cereal and legume-based feed ingredients exceeded the MPC. By mixing corn, barley and soybeans, unfavourable in aflatoxin B 1 concentration with other favourable in this toxin ingredients managed to reduce its content in the composition of complete mixed feed PK-5 and PK-6to 0.23 mg/kg. Moreover, aflatoxin B 1 concentration in the formulation of these mixed feeds in both phases of feeding does not exceed the tolerance amount-0.25 mg/kg. According to two metabolism trials using rearing flocks and laying hens, the joint introduction of probiotic Bifidumbacterin at the rate of 5 doses per 200 heads and preparation Santochinum at a dose of 125 g/t feed in the diet with tolerance level of aflatoxin B 1 increased significantly the digestibility coefficients of organic matter, crude protein, crude fiber and nitrogen-free extractives, as well as the best protein conversion into products.
