Bentonite is a kind of feed additive material with a long history. In the Ministry of agriculture, it is presented in the catalogue of feed ingredients.
Bentonite in the feed was originally used as a mineral binder material, the prepared feed grains and storage is not easy to harden. In the later stage, it was found that the growth performance of the livestock and poultry was significantly improved. Along with the thorough research, the discovery of bentonite to improve the animal gastrointestinal environment, the control of diarrhea has obvious effect. As a kind of animal gastrointestinal health additives, bentonite has gradually been recognized.
With the further study of the mechanism of livestock and Poultry Pathogenic Mechanism in foreign countries, the mould toxin slowly appeared in public view. A large number of studies have indicated that the cause of the disease of livestock and poultry is the accumulation of the toxin in the body of the animal. Foreign studies have been carried out to name and classify the toxin of the mold, and to analyze the chemical structure and the mechanism of the fungus. For livestock and poultry influence largest toxoid respectively: Aspergillus flavus toxin, corn gibberellic ketene, vomitoxin, ergot toxins, ochratoxin A, a new study suggests. Mould toxin is common in feed, and it is difficult to remove by heating process.
One of the effective methods to remove the mold toxins from animal and poultry is the method of adsorption. The toxin produced by the mold is adsorbed on the carrier and is not absorbed by the passive object, thereby reducing the toxin to the livestock and poultry.
Bentonite is a kind of highly effective adsorbent, especially for aflatoxin. Yellow aspergillus toxin molecular weight is relatively small, with a certain polarity, by ion exchange effect firmly adsorbed on bentonite, not legible adsorption.
The main composition of the adsorption function of bentonite is: montmorillonite, and the associated minerals are mainly quartz, calcite, mica, dolomite, etc.. Bentonite can be obtained by purification process of high purity montmorillonite products. Thus, the adsorption capacity and adsorption efficiency of the mould toxin could be improved greatly.
Montmorillonite lamellar aluminum magnesium silicate minerals, composed of by two layers of silicon oxygen tetrahedron, clip a layer of alumina octahedral a single layer, the thickness of only the ropes of, slice end mask negative charge, off the mask of variable charge and lamellar stacking forming montmorillonite particles, its theoretical specific surface area up to /.
Montmorillonite surface after the special craft processing, improve the surface property, has good adsorption properties of corn zeranol and sesquiterpene mycotoxins.
Montmorillonite after special reaming processing capacity increase and improve its layer pore size and porosity, can significantly improve the vomiting toxin, water soluble high mycotoxin adsorption properties.
Current domestic livestock and poultry main pollution type:
Pig: vomiting toxin and corn
Cattle (cow): aflatoxin, vomiting toxin, corn
Poultry: vomiting, aflatoxin
Aquatic products: Aflatoxin
