Problems solved by technology

Montmorillonite and activated carbon cause good adsorption and are widely used in mycotoxin detoxification agents, but because of their non-specific adsorption, it is easy to adsorb a large amount of other nutrients in the feed, which may cause nutritional deficiencies in animals; different sources and Activated carbon as a component has defects such as large differences in th

Example Embodiment

[0021] The preparation method of the above-mentioned livestock and poultry feed T-2 toxin composite adsorbent comprises the following steps:

[0022] 1) The modified activated carbon is obtained by placing the powdered activated carbon at a temperature of 1000-1200° C. for 3-5 hours with oxygen barrier heat treatment; the mesopore volume of the modified activated carbon is 0.570-0.685 cm 3 / g, the specific surface area is 1030~1078m 2 / g;

[0023] 2) will take by weighing modified montmorillonite, selenomethionine hydroxyl analog, yeast cell wall polysaccharide, modified activated carbon and curcumin according to the above-mentioned weight percentage, for subsequent use;

[0024] 3) Mixing the modified montmorillonite, selenomethionine hydroxyl analog, yeast cell wall polysaccharide, modified activated carbon and curcumin uniformly to obtain the T-2 toxin composite adsorbent for livestock and poultry feed.

[0054] Example 1

[0055] The preparation method of the above-mentioned livestock and poultry feed T-2 toxin composite adsorbent 1 comprises the following steps:

[0056] 1) The modified activated carbon is obtained by placing the powdered activated carbon at a temperature of 1100° C. for 4 hours with oxygen insulation and heat treatment; the mesopore volume of the modified activated carbon is 0.570-0.685 cm 3 / g, the specific surface area is 1030~1078m 2 / g;

[0057] 2) 62.0% of modified montmorillonite, 1.0% of selenomethionine, 20% of yeast cell wall polysaccharide, 15% of modified activated carbon and 2.0% of curcumin will be weighed according to the above-mentioned weight percentage, for subsequent use;

[0058] 3) Mixing the modified montmorillonite, selenomethionine hydroxyl analog, yeast cell wall polysaccharide, modified activated carbon and curcumin evenly;

Example Embodiment

[0059] Example 2

[0060] The method for preparing livestock and poultry feed T-2 toxin composite adsorbent 2 in the present embodiment is basically the same as the preparation method in the embodiment, and the difference lies in:

[0061] The raw materials of T-2 toxin composite adsorbent 2 in livestock and poultry feed are 65% modified montmorillonite, 1.0% selenomethionine hydroxy analog, 21% yeast cell wall polysaccharide, 10% modified activated carbon according to weight percentage. and 3.0% curcumin.

Abstract

The invention discloses a livestock feed T-2 toxin compound adsorbent as well as a preparation method and an application thereof. The livestock feed T-2 toxin compound adsorbent is prepared from raw materials in percentage by weight as follows: 60%-65% of modified montmorillonite, 1.0%-1.5% of selenomethionine hydroxy analogs, 18%-21% of yeast cell wall polysaccharide, 10%-15% of modified activated carbon and 2.0%-3.0% of curcumin through uniform mixing. A proper dosage of detoxification agents synthesized according to the formula are added to daily ration of broilers, which proves that the adsorbent can effectively relieve the toxic effect caused by T-2 toxin, particularly can improve the growth performance of the broilers and promote body health as compared with existing commercially available adsorbents; a better effect can be obtained after a few adsorbent is added and the production cost is reduced.

Description

technical field [0001] The invention relates to the field of composite adsorbents, in particular to a composite adsorbent for livestock and poultry feed T-2 toxin and its preparation method and application. Background technique [0002] T-2 toxin belongs to the group of trichothecenes and is produced by fungi of the genus Fusarium. T-2 toxin is widely present in various grain crops, and the detection rate of T-2 toxin in my country's grain is 80% (Liu et al., 1996). Corn, wheat, barley, oats and rye are the crop species most polluted by T-2 toxin. T-2 toxin is highly toxic, and high doses of feed containing T-2 toxin can lead to acute poisoning of livestock and poultry. The main symptoms are vomiting, hemorrhagic diathesis, and death from cardiovascular dysfunction (Parent et al., 2004). Low-dose intake can also lead to chronic poisoning. The main symptoms are decreased production performance, including loss of appetite, decreased feed intake, decreased body weight, decrea...
