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 the strength of binding to mycotoxins. These problems make it difficult to evaluate the real adsorption effect and clinical application effect of many mycotoxin adsorbents.
Therefore, currently commonly used feed mycotoxin adsorbents often only focus on the adsorption and removal of toxins by the product itself, while ignoring the protective effect of additives on the body's health

Embodiment 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) Put the powdered activated carbon at 1100°C for 4 hours to obtain modified activated carbon; 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) Weighing 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 according to the above weight percentage, and set aside;

[0058] 3) Mix the modified montmorillonite, selenomethionine hydroxyl analog, yeast cell wall polysaccharide, modified activated carbon and curcumin evenly; obtain T-2 toxin composite adsorbent 1 for livestock and poultry feed.

Embodiment 2

[0060] The method for preparing livestock and poultry feed T-2 toxin composite adsorbent 2 in this embodiment is basically the same as that in the embodiment, except that:

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...
