Abstract

The invention discloses an adsorbent for mycotoxin in a feed and a preparation method thereof, aiming at providing an aluminosilicate adsorbent for adsorbing mycotoxin in a mouldy animal feed. The adsorbent is prepared by using medical stone powder as a raw material, immersing the medical stone powder in a certain ratio of antibacterial material quaternary ammonium salt-myristyl trimethyl ammonium bromide, stirring, washing, filtering, drying, and grinding into powder. According to the invention, the processed modified medical stone powder has an increased internal surface area and an enhanced adsorption capacity; by adding the modified medical stone powder in the feed, the animal immunity function and production performance can be raised, and the toxic action of mycotoxin in the feed to animals can be alleviated.

Description

technical field

[0001] The invention relates to the field of feed safety, in particular to a preparation method of a feed mycotoxin adsorbent. Background technique

[0002] According to the Food and Agriculture Organization of the United Nations, about 25% of the world's grains are polluted by mycotoxins to varying degrees, and 5%-7% of grain and feed lose their feeding value due to mildew, and livestock and poultry deaths caused by mycotoxins , productivity decline, reproductive dysfunction and other livestock and poultry mycotoxin poisoning incidents occur frequently, and the economic losses are very serious. The contamination of feed by mold and mycotoxins has become a problem that cannot be ignored in the production of feed and animal husbandry. At the same time, mycotoxins can also remain in livestock and poultry products, bringing great safety hazards to human health. It is an urgent task for the development of animal husbandry to find a suitable and effective method...

Examples

Embodiment Construction

[0021] The technical solutions of the present invention will be further described below through examples.

[0022] (1) Modification test: take 30g natural medical stone, pulverize to 100 mesh particles, add it in 100mlA solution, described A solution is to contain the tetradecyl trimethyl bromide that mass fraction is 10% Ammonium chloride, ethanol solution with a volume concentration of 50%; oscillate in a constant temperature water bath at 60°C for 1 hour, centrifuge and pour off the supernatant, and repeat the operation once; after filtering, soak in 100ml of distilled water, shake in a constant temperature water bath at 60°C for 1 hour; filter again , placed in an oven at 105°C for 3 hours, ground and pulverized for later use after cooling.

[0023] (2) In vitro test:

[0024] A. The effect of different additions of unmodified medical stone on the adsorption rate

[0025] Such as figure 1 As shown, the amount of adsorbent added is 10, 25, 50, 75, and 100 mg respectively...
