Problems solved by technology

This formula can reduce heavy metal residues in animal products, but the composition of the formula is complex, which greatly increases the production cost of animal farmers. It is of great economic value to simplify the formula components and study a low-cost adsorbent that can reduce heavy metal residues in animal products.

preparation example Construction

[0026] The preparation method of the composite adsorbent is as follows: drying glucomannan and bentonite separately, mixing in proportion, pulverizing, and passing through a 30-60 mesh sieve to obtain the product.

[0027] Glucomannan is a commonly used organic adsorbent. It is used in feed to detoxify feed. It has the characteristics of low addition amount, adsorption of various mycotoxins, and less adsorption of nutrients. It will not produce other toxic substances and will not affect feed. glucomannan has a good adsorption effect on aflatoxin, and has a good adsorption effect on zearalenone (ZEN), T-2 toxin, and deoxynivalenol. Fusarium enol (DON) and ochratoxin A also have a certain adsorption effect, but the adsorption rate is low and the adsorption capacity of mycotoxins by products made of different species of yeast is quite different.

[0028] Bentonite is a polar adsorbent with charges on the surface. The adsorption of bentonite mainly includes physical adsorption and...

Embodiment 1

[0035] The composite adsorbent is composed of glucomannan and bentonite, and the mass ratio of glucomannan and bentonite is 9:1.

[0036] Glucomannan particle size <100 mesh.

[0037] Bentonite particle size <100 mesh.

[0038] The preparation method of the composite adsorbent is as follows: drying the glucomannan and the bentonite separately, mixing in proportion, pulverizing, and passing through a 60-mesh sieve to obtain the product.

Embodiment 2

[0040] The composite adsorbent is composed of glucomannan and bentonite, and the mass ratio of glucomannan and bentonite is 8:1.

[0041] Glucomannan particle size <100 mesh.

[0042] Bentonite particle size <100 mesh.

[0043]The preparation method of the composite adsorbent is as follows: drying the glucomannan and the bentonite separately, mixing in proportion, pulverizing, and passing through a 60-mesh sieve to obtain the product.

Abstract

The invention discloses a composite adsorbent for relieving animal heavy metal poisoning, a preparation method and application thereof. The composite adsorbent is prepared by mixing glucomannan and bentonite in a specific proportion, and has simple formula and low cost. When the composite adsorbent is added to a feed in an appropriate amount, the heavy metal poisoning of animals can be effectivelyrelieved, and the adsorption of heavy metals by the glucomannan and the bentonite is also effectively utilized.

Description

technical field [0001] The invention belongs to the technical field of feed industry, and in particular relates to a composite adsorbent for alleviating animal heavy metal poisoning, a preparation method and application thereof. Background technique [0002] In recent years, the rapid development of my country's economy and the improvement of people's living standards have greatly promoted the development of the livestock and poultry breeding industry. Feed is the source of animal food safety. Feed safety is not only related to the safety and health of animals, but also affects the economic benefits of the breeding industry. At the same time, it directly or indirectly affects human health. Heavy metal pollution is currently one of the main factors affecting animal food safety. . The heavy metal elements commonly referred to in the farming and food industries mainly refer to lead (Pb), cadmium (Cd), mercury (Hg) and metalloid arsenic (As) with significant biological toxicity...
