Description

The invention relates to veterinary medicine and can be used in the preparation of feed for farm animals and birds in order to reduce the negative impact of toxins on their productivity when using sorption products based on aluminosilicate modified with a complex of organic acids, iodine and silver.

High productivity means the genetically determined ability of animals to transform feed nutrients into elements of tissues, organs, productive secrets that are used as food products or technological raw materials.

This ability is due to the intense flow of metabolism at all levels and stages. Moreover, all the organs of the animal involved in the transformation of the feed into the final product work in extreme conditions. Naturally, under such loads, the vitality of the body is simply not enough to overcome the effects of negative external factors - diseases of various etiologies, stresses, poor or poorly balanced feeding, etc. The problem of using insufficiently high-quality feed raw materials is especially acute. This is an increased concentration of heavy metals, microbial contamination, mycotoxins. More than 30% of compound feeds contain mold mycotoxins. It is generally recognized that safe levels of mycotoxins and safe feeds do not exist. And if animals with low productivity have enough internal reserves to neutralize toxins, then highly productive animals are not able to withstand the harmful effects of pathogenic microorganisms. In this regard, to maintain high productivity, it is advisable to use toxin converters, primarily produced by pathogenic fungi.

Currently, the most used means to protect animals from the damaging effects of contaminated feeds is the use of mycotoxin-binding sorbents.

The action of sorbents is based on the ability to remove mycotoxins from the gastrointestinal tract. Sorbents must quickly bind and effectively retain mycotoxins at various levels of acidity. The negative quality of the sorbent materials is their low specificity, which results in the binding of nutrients (essential fatty acids, vitamins, amino acids) and drugs (disposal of mycotoxins in animal feed with various adsorbents, Toxicology Letters, 122 (2001), 179-188).

The use of organic acids with pronounced bactericidal activity is known. In recent years, highly effective preparations based on organic acids with bactericidal, antiseptic and fungicidal effects have been developed (Instructions for use Cuxacid S, LOMANN ANIVAL HELTH, Germany).

They can effectively preserve feed and destroy the already formed toxins. In addition, many acids (succinic, lactic) stimulate the protective functions of the body and improve digestion. The disadvantage of such drugs is the use of active acids such as formic and acetic acids, which at high dosages can lead to acidosis. Concentration, which is not sufficient to kill mold due to a change in the pH of the medium, can create stress for molds, which, in turn, stimulates the formation of toxins.

Known feed product (feed additive) for productive farm animals (birds), including sorption material based on aluminum - aluminosilicate (zeolite), (Patent for invention RU No. 2262863 from 10.27.2005), which is the closest in technical essence and the achieved result, and adopted as a prototype.

Known feed additive has adsorption, detoxification, anti-toxic properties and is used to prevent diarrhea, heavy metal poisoning and mycotoxins.

An object of the present invention is to provide a feed product for productive farm animals (birds).

The technical result that the present invention is directed to is the development of a product that effectively sorb and remove toxins and heavy metals from the body, inactivates mycotoxins, and also increases the protective and digestive functions of the animal’s body.

The feed product for productive farm animals contains aluminosilicate as a sorption material and additionally includes a silver complex with polyvinylpyrrolidone, lactic acid, succinic acid or its salts, citric acid and iodine in the following ratio of ingredients, wt.%:

The tool is prepared as follows:

1. Purified water corresponding to SanPiN 2.1.4.1074-01, GOST R 51232, enters the ionizer, where it is saturated with silver to a concentration of 2-25 mg / liter;

2. In the blending container, the PVP is mixed with ionized water;

3. The PVP solution with silver enters mixer No. 1, and liquid fractions of organic acids enter the same. Everything is mixed with aluminosilicates, characterized by sorption properties: water capacity 320-468%, fat capacity 208-324%;

4. From the mixer, the product enters the oven to remove excess moisture;

5. From the oven, the mixture enters the mixer No. 2, where the final mixing with organic acids and filler-aluminosilicate;

6. From the mixer No. 2, the finished product enters the packaging and labeling line.

The developed product is used to neutralize toxins in the feed and gastrointestinal tract of highly productive animals and birds. Its composition includes only natural components that do not have negative side effects on the animal's body.

The developed tool performs the following functions: inhibits the development and destroys existing toxins, improves the detoxification function of the liver.

The presence of mycotoxins in feed leads to a decrease in productivity, reproductive qualities and the immune state of animals. Mycotoxins differ in chemical structure, toxicity and mechanism of action. A common symptom of all mycotoxins is toxicity mainly with respect to eukaryotic organisms. The most commonly used classification of mycotoxins is molecular structure, according to which aflatoxins, zearalenone and its derivatives, fumonisins, ochratoxins, etc. are distinguished.

Example 1

To identify the preservative and antioxidant effects of the product, a compound feed sample for pigs SPK-3 was selected. Compound feed was divided into 2 parts of 1 kg. In one of the parts was added 0.1% of the product containing the following ingredients, in wt.%:

Both parts of the feed were laid in a plastic bottle without a lid in a thermostat at a temperature of 24 ° C. In order to increase humidity, a container with distilled water was placed in the thermostat. The exposure time in the experiment is 3 months. At the end of the experiment, a positive effect of the complex on the content of mycotoxins in the feed (table 3) and nutrients was revealed. During the experiment, it was revealed that the exchange energy was 18% higher than the control. The content of fat-soluble vitamins is on average 15% higher.

As a result of a series of experiments, the antifugal effect of the complex at a dosage of 0.2-0.5% was reliably detected.

Example 4

To identify the impact of the complex on the health of highly productive animals, an experiment was conducted in the breeding farm of cattle of the Leningrad region.

An experimental group of dry cows was formed in the amount of 84 goals. The control was a group of dry cows in the amount of 83 animals. The content of all animals is identical. In the feed of the experimental group was added a product at the rate of 0.2%. The duration of the experiment is 8 months. During this time, 20 animals were rejected in the control group due to various diseases, and 6 in the experiment. Spring cows in experiment 9 versus 11 in the control. The average milk yield in the experimental group was 6% higher. The main reason for rejection - hepatosis, clearly indicates an increased content of mycotoxins in the digestive tract of cows of the control group compared with the experimental group.

Example 5

The main heavy metals, with which poisoning of farm animals and birds are most often associated, are mercury, cadmium and lead. To determine the influence of the developed feed product on the content of these metals in the body of animals and birds, 2 groups of broiler chickens were formed at the age of 3 days. (With a very high metabolism, broiler chickens are most suitable for this experiment). In the feed of the control group was added 0.1% of the feed product of the following composition, wt.%:

lactic acid - 8.0

succinic acid (or its salts) - 5.0

citric acid - 5.0

PVP (polyvinylpyrrolidone) - 5.0

silver - 0.0001

iodine - 0.01

aluminosilicate - the rest is up to 100%

After slaughter at 45 days of age, biochemical analyzes to determine the residual amount of heavy metals in the organs and tissues of poultry showed that the use of this composition helped to reduce the content of mercury, cadmium and lead in the body of broilers. So, the amount of mercury in depot organs (liver and kidney) of chickens in the experimental group was 1.5 times less than in the control group. Under the action of the complex, cadmium accumulation in the liver and kidneys decreased in the experimental group by 2.3 times, and lead - by 2.4 times in comparison with the control group.

Item name Biomedical requirements and dignity. norms prod. raw materials Control group Experienced group Mercury Not more than 0.01 mg / kg 0.005 mg / kg 0.003 mg / kg Cadmium Not more than 0.05 mg / kg 0.04 mg / kg 0.017 mg / kg lead No more than 1,0 mg / kg 0.8 mg / kg 0.33 mg / kg

Thus, the results of the experiment showed that the use of the developed feed product positively affected the quality of broiler meat. At the same time, with an increased content of heavy metals in compound feed, the level of residual amounts of mercury, cadmium and lead in the liver and kidneys of the bird significantly decreased and the accumulation of heavy metals in poultry meat was completely prevented.
