Process for preparing feed nano additive to adsorb fungal toxin from feed

Abstract

A feed nano additive for adsorbing fungal toxin in feed is prepared through proportionally mixing montmorillonite, sodium chloride and water, stirring, water washing, preparing pulp again; adding glucomannan while high-speed stirring, reaction, ageing, water washing, dewatering; drying filter residue and breaking. Its advantages are broad-spectrum adsorption of different toxins, high adsorptive power, no influence of pH value, low residual and low dosage (0.02-0.2%).

Description

Technical field [0001] The invention relates to a preparation method of a nano feed additive capable of adsorbing mycotoxins in feed. Background technique [0002] According to statistics, 25% of the world's grains are infected by mycotoxins. Common mycotoxins are aflatoxin, zearalenone, ochratoxin, T-2 toxin, fusarium toxin, fumonisin, emeticin, ergot alkaloid and so on. The milder mycotoxins in the feed will reduce the livestock and poultry’s feed intake, poor growth, and lower feed efficiency. The severe ones will cause the growth of the animals to be blocked, poisoned or killed, causing greater economic losses; more serious, residues in livestock products The mycotoxins can endanger human health through the food chain. A large number of epidemiological studies have shown that aflatoxin is one of the important causes of human liver cancer. Therefore, eliminating the harm of mycotoxins is a major problem that needs to be solved urgently in animal husband...

Problems solved by technology

Physical methods, chemical methods, and biological methods all have certain detoxification effects, but there are disadvantages such as time-consuming, secondary pollution, destruction of nutrients in feed, and incomplete detoxification. There are more or less deficiencies, and it is difficult to practically promote and apply it in the feed and breeding industry on a large scale; and the adsorption method is valued by academia and industry because of its safety and convenience, and no adverse effects on livestock and poultry.

[0004] At present, natural zeolite, activated carbon, etc. are often added to compound feed to absorb mycotoxins, and the additive dosage generally needs to be higher. Poor feed palatability, loss of appetite, constipation and other phenomena in livestock and poultry, affecting the normal growth of livestock and poultry

More importantly, ordinary adsorbents have a narrow range of adsorption of mycotoxins. Although they can effectively adsorb aflatoxins, their efficacy against zearalenone, ochratoxin, T-2 toxin, and fusarium toxin is very limited.
