Problems solved by technology

[0004] In view of related technologies, the inventor believes that although the montmorillonite modified by organic ammonium salt can improve the adsorption effect of montmorillonite on mycotoxins, the effect is relatively single, and the detoxification effect needs to be further improved

preparation example 1

[0032] Weigh a certain amount of montmorillonite, put it in deionized water, stir, and prepare a suspension with a mass fraction of 8%, and heat it to 60°C, and stir for 10 minutes; another certain amount of octadecyl trimethyl bromide Ammonium chloride, dissolved in deionized water, is prepared into a quaternary ammonium salt solution with a concentration of 10%; according to the volume ratio of the quaternary ammonium salt solution and the suspension of montmorillonite is 1:5, the quaternary ammonium salt solution is added to the montmorillonite In the desoiled suspension, continue stirring at 60°C for 5 hours; filter, and wash the precipitate with hot ethanol aqueous solution until there is no Br in the washing liquid - (with 0.1mol / L AgNO 3 inspection), and the sediment was dried at 65°C to obtain salt-modified montmorillonite.

Embodiment 1

[0035] A mycotoxin adsorbent for feed, made of the following raw materials, 150g Saccharomyces cerevisiae cell wall, 500g modified montmorillonite, 100g benzoic acid, 150g sodium benzoate and 100g ε-polylysine, wherein ε-polylysine The molecular weight is 3800.

[0036] The specific preparation method of the mycotoxin adsorbent for feed is as follows. Accurately weigh the cell wall of Saccharomyces cerevisiae, modified montmorillonite, benzoic acid, sodium benzoate and ε-polylysine, and mix well to obtain the mycotoxin adsorbent.

Embodiment 2- Embodiment 12

[0038] The mycotoxin adsorbents for feed in Example 2-Example 12 were all prepared by the method in Example 1, the only difference being that the dosage of each raw material component was different, see Table 2 for details:

[0039] The dosage of each raw material component in the embodiment 2-embodiment 12 of table 2

Abstract

The invention relates to the field of mycotoxin adsorbents, and particularly discloses a mycotoxin adsorbent for feed and a preparation method thereof. The mycotoxin adsorbent for feed is prepared from the following raw materials in parts by weight: 15-20 parts of saccharomyces cerevisiae cell walls, 50-70 parts of modified montmorillonite, 10-15 parts of benzoic acid, 10-15 parts of sodium benzoate and 7-11 parts of epsilon-polylysine. The preparation method comprises: uniformly mixing the saccharomyces cerevisiae cell wall powder, the modified montmorillonite, the benzoic acid, the sodium benzoate and the epsilon-polylysine according to a proportion to obtain the mycotoxin adsorbent for feed. According to the mycotoxin adsorbent for feed, the detoxification effect is achieved, meanwhile, the gastrointestinal tract environment of piglets can be improved, and the daily feed intake and daily weight gain of the piglets can be improved.

Description

technical field [0001] The present application relates to the field of mycotoxin adsorbents, more specifically, it relates to a mycotoxin adsorbent and a preparation method thereof. Background technique [0002] Mycotoxins are toxins secreted by molds produced during the storage of feed or raw materials. Common mycotoxins include aflatoxin, deoxynivalenol and zearalenone. Aflatoxin can easily lead to a decrease in feed intake and feed conversion rate of pigs. If the sow eats it, it will easily lead to growth retardation and even death of piglets; in addition to reducing the feed intake of pigs, vomitoxin will mainly cause vomiting in pigs, which will seriously affect the normal growth and development of pigs; zearalenone will mainly cause Abortion and stillbirth of pregnant sows, etc. [0003] In order to reduce the contamination of feed by mycotoxins, existing enterprises generally add mycotoxin adsorbents to feed, and use mycotoxin adsorbents to absorb mycotoxins, so that...
