Effect of mycotoxins on animal ORGANISM.
Mycotoxins – toxic substances that can be formed in vegetables, fruits, and animal feeds. Mycotoxins are products of vital activity of fungi such as Fusarium, Aspergillus, Penicillium, etc. Infection of grain and animal feed with mycotoxins can occur at any stage of its manufacture:. During harvesting, storage, processing or transport. Today, the mycotoxin contamination of feed is a serious problem for livestock farms and enterprises.
The presence of mycotoxins in the feed negatively affect the productivity of livestock, as well as reproductive and immune status of cattle. In addition, experts in the field of toxicology have proven the ability of mycotoxins to accumulate . That is, the toxic substance can be in meat, milk or eggs. Thus, from the negative effects of mycotoxins is suffering not only livestock, but also a person who is a consumer of animal products.
To combat the mycotoxin adsorbents are used – special substances that prevent or minimize the devastating effects of mycotoxins on animal organism. First adsorbent was released in 1987 year. Since it is one of the most effective methods for the prevention and treatment of mycotoxicosis in animals.
Today, there are a great number of antitoxic drugs. Each of them has its own nature, and different impact on a group of mycotoxins. How to choose the most optimal and effective variant?
Realizing the seriousness of the situation of grain and animal feed contamination by mycotoxins, a research group was created in 2012, which included experts from different fields. The scientists faced the task – to create a high-quality mycotoxin adsorbent.
ANALYSIS of mycotoxin adsorbents.
In the first stage of research scientists analyzed the Ukrainian mycotoxin adsorbents. They studied its features, the ability to adsorb toxic substances (toxins).
In the experiment, it was found out that with the help of adsorption only polar mycotoxins are neutralized . Non-polar toxins are not adsorbed.
In addition, the scientists studied the desorption process of mycotoxins in the intestine. Having completed a number of studies, experts have concluded that the smaller the particle size, the greater the area of the active surface. That is, the efficiency of removing toxins will depend on the sorption capacity and dosing.
|Generation of binders||Types||Permissible input rate, kg / t|
|I||Carbon binders||Not more than 20|
|II||Polymer binders and binders from natural clays||Not more than 20|
|III||Complex organic||Not more than 5|
|IV||Silicon, superfine (MIKASIL BP)||Not more than 2|
In the second stage of research scientists have studied and analyzed a variety of potential raw material. Been working on his transformation to obtain adsorbent properties with respect to the negatively charged toxic substances (toxins).
Adsorbent is a body with a porous surface. The adsorption process and the absorption of toxic substances occur exactly in the pores.
There are several types of pores:
- Macropores (effective radius of more than 500 ?) – the pores having the largest size. Their specific surface area – from 0.2 to 0.5 m2/g. During adsorption are not filled. Performed the role of paths to the surface of the adsorbing pores.
- Micropores (radius of 20-500 ?) – pores with stratified adsorption mechanism. Size surface 100-200 m2/g.
- Micropores (20 ?) – fine pores. The surface reaches 800 to 1000 m2/g
The molecular mass of mycotoxins is 200-550 Da (atomic unit), the most effective pore radius in the binder should be 7-9 ? (angstrom)..
Innovative energy efficient technology was created on the third stage of research, thanks to which it was possible to enter the low cost price. Thus remained high adsorbing properties towards toxins with positive and negative charge.
It should be noted that mycotoxins have their own classification. For each inherent in their producer, the affected area and the toxic effect. Therefore, means should be selected depending on the type of mycotoxin. But what if you want to eliminate the adverse effect of several mycotoxins? In this case, you can use the universal adsorbent MIKASIL from the company “Globus”. Ukrainian and foreign experts worked for a long time to create it. The result was a versatile product that combats practically all known mycotoxins. The product has passed all the required tests and meets all the established quality standards.
