Abstract

Four commercial mould inhibitors and antimycotoxins feed additives (Detox®, Mycotox®, Toxinil® and Nutritox®) were evaluated for their effect against fungi contaminating the poultry ration and also the possibility to detoxify mycotoxin. Starter Corn-Soya ration proven after examination to be contaminated with fungi, aflatoxin and ochratoxin-A with an average pH 6.7 and 14 % moisture content. Nine cloth bags were sterile autoclaved then each one was filled with 10 Kg. from this ration.  Each feed additive was added to the contaminated ration at equal and higher concentration than that of the manufacturer recommendations (Detox® 0.1 & 0.2%, Mycotox® 0.1 & 0.2%, Toxinil® 0.3 & 0.5% and Nutritox® 0.05 & 0.1%) then all bags were stored for 2 weeks at room tempera- ture. The total fungal count, pH and moisture content were determined at the end of the 1st, 7th and 14th day of the storage period, while determination of aflatoxin and ochratoxin-A was applied at the end of 7 and 14 day from each treatment. Detox® showed the best mould inhibition results at a concentration of 0.2%, then Toxinil® at 0.5%, followed by Detox at 0.1%. On the other hand Mycotox® was the best detoxifying agent for both aflatoxin and ochratoxin-A especially at a concentration of 0.2%, while Toxinil® at 0.5% was effective against aflatoxin only. Those concerned with feeds and feeding in processing plants and poultry farms should recognize the differences in nature and use of both mould inhibitors and mycotoxin detoxifying agents.
