Problems solved by technology

However, the cost of the enzymatic degradation method prepared by the current antifungal agent is relatively high, which greatly limits its use; the traditional physical adsorption method is to add substances that can absorb mycotoxins in the feed, and the method is relatively simple and cannot effectively absorb most molds. , although it can prevent or slow down the mildew of the feed, it cannot effectively eliminate the mycotoxins in the moldy feed; while the enzymatic hydrolysis method has a good effect of removing mold in the process of production and preparation, but the cost of preparation is often too high
[0004] Traditional mold removers have strong selectivity for the adsorption of various mycotoxins. For example, ordinary hydrated aluminosilicate adsorbents can only adsorb aflatoxins, but have poor adsorption capacity for mycotoxins such as zearalenone. , the palatability of antifungal agents is generally poor

preparation example Construction

[0018] Preparation method, the steps are as follows:

[0019] 1) After using ferric chloride to modify diatomite and cetylpyridine to modify montmorillonite, then mix the modified diatomite and montmorillonite according to the proportion;

[0020] 2) After mixing sorbic acid, sodium diacetate and propionic acid according to the proportion of the components, they are evenly mixed with the raw materials of step 1) to make them into powder;

[0021] 3) The compound feed anti-mold and mildew-removing agent is added according to 0.5-1% of the total amount of feed each time.

Embodiment 1

[0023] Raw materials are weighed by weight percentage: 58% of diatomite, 22% of montmorillonite, 6% of sorbic acid, 8% of sodium diacetate, and 6% of propionic acid. Made into powder to achieve the coefficient of variation of mixing uniformity: CV≤5%. The mixed additive is added to the fattening pig compound feed with a water content of 13.9% according to the proportion of 1%, and the coefficient of variation of the mixing uniformity is achieved after mixing: CV≤7%. Store in a cool and dry room, with a shelf life of 3 months in summer. The maximum allowable value of mycotoxins in compound feed for fattening pigs in my country is: aflatoxin B1≤20μg / kg, vomitoxin≤1mg / kg, zearalenone≤500μg / kg kg. The samples were tested for mycotoxins on the 2.3.4.5 month respectively, and the test results are as follows:

Embodiment 2

[0026] Raw materials are weighed by weight percentage: 65% of diatomite, 15% of montmorillonite, 5% of sorbic acid, 10% of sodium diacetate, and 5% of propionic acid. Made into powder to achieve the coefficient of variation of mixing uniformity: CV≤5%. The mixed additive is added to the fattening pig compound feed with a water content of 13.9% according to the proportion of 1%, and the coefficient of variation of the mixing uniformity is achieved after mixing: CV≤7%. Store in a cool and dry room, with a shelf life of 3 months in summer. The maximum allowable value of mycotoxins in compound feed for fattening pigs in my country is: aflatoxin B1≤20μg / kg, vomitoxin≤1mg / kg, zearalenone≤500μg / kg kg. The samples were tested for mycotoxins on the 2.3.4.5 month respectively, and the test results are as follows:

Abstract

The invention provides a mildew-proof and mildew-removing agent of a compound feed and a preparation method of the mildew-proof and mildew-removing agent. The mildew-proof and mildew-removing agent is prepared from the following raw materials in percentage by weight: 55%-68% of diatomite, 15%-25% of montmorillonite, 4%-9% of sorbic acid, 6%-10% of sodium diacetate and 5%-7% of propionic acid. The mildew-proof and mildew-removing agent is added into different feeds according to a certain ratio, so that mildew is prevented from growing in the feed and the growth of mildew toxins is stopped; the toxins can be effectively removed; and the mildew-proof and mildew-removing agent has the advantages of good palatability, high efficiency in disinfection, broad-spectrum antibacterial property, safety and relatively low cost, and is convenient for further popularization and application.

Description

technical field [0001] The invention relates to the field of feed science and technology, in particular to a compound feed anti-mold and mildew-removing agent and a preparation method thereof. Background technique [0002] At present, there are many types of antifungal agents for feed that are allowed to be used in our country. Due to the fact that during the long-term storage of feed, a large number of mildew will occur, which will bring a huge loss to some manufacturers. The use of antifungal agents is harmful to the human body. It is non-toxic, but has a strong inhibitory effect on various molds, bacillus and gram-negative bacilli, and basically has no effect on the growth of yeast. It has a good anti-mold effect in feed and is widely used in feed production. [0003] At present, a variety of physical, chemical and biological methods can be used to degrade or adsorb mycotoxins in feed, so as to prevent the damage of toxins to breeding animals. However, the cost of the en...
