Description

The invention relates to the production of feed and is intended for pigs.

A mineral supplement containing permite is known, which is used in animal husbandry for fattening young pigs (1). The prototype of the claimed invention is a feed additive "Tsamax" for animals, containing clinoptilolite and elemental sulfur (2).

The disadvantage of these feed additives is the lack of sulfur content as an element in the composition of the natural mineral (1), which affects the productivity of pigs, and the feed additive (2) consists of two components and requires a cooking procedure.

The essence of the invention lies in the use in feeding feeding pigs of the new local natural mineral “Vodnit” of the Vodinsky deposit of the Krasnoyarsk district of the Samara region.

The optimal dosage when including natural minerals (zeolite tuffs) in the main diet of pigs is 2-4% (3).

The objective of the invention is the use of the natural mineral "Vodnit" as a natural adsorbent for the removal of heavy metals and toxic elements from the body of pigs, increase productivity.

The color of the pieces of the rock of the natural mineral "Vodnit" is from light yellow to gray-yellow. It crumbles well, boils when it hits 10% hydrochloric acid, with a characteristic smell of sulfur. It is a polymineral mixture consisting of the following components.

From sulfate the content in the rock was noted: Gypsum (Ca (SO ₄ ) · 2H ₂ O).

Of the carbonates, the following contents were noted: Calcite (CaCO ₃ ) and Dolomite (CaMg (CO ₃ )).

The advantage of the natural mineral “Vodnit” lies in the fact that it contains sulfur and calcium to a large extent.

In the animal body, sulfur is present mainly in the form of cysteine, cystine, methionine, taurine, glutathione, ergotionine, sulfur-containing polysaccharides, insulin and thiamine (A.Hening, 1976).

Sulfur is part of bile and sperm. In all tissues (with the exception of cartilage), sulfur is mainly found in amino acids - cystine, cysteine, methionine, which in turn stimulate the growth of animals and skin derivatives (hair, hair, horns, etc.) (V.I. Georgievsky, V.T. Samokhin, 1979; S.I. Athos, 1970).

Calcium is an indispensable component of the skeleton and teeth. Calcium ions occupy key positions in the transmission of nerve excitation, maintaining the integrity of cell membranes, the sarcoplasmic network of muscle cells, participate in muscle contraction, reduce membrane permeability, reduce the ability of tissue colloids to bind water, participate in all stages of blood coagulation, activate enzymes (V.T. Lapshin, 1988; B.D. Kalnitsky, 1990).

The average value of the elemental composition of the natural mineral “Vodnit” was studied in the laboratory of X-ray diffractometry, electron and probe microscopy, NICH GOU VPO Samara State Technical University (Table 1).

The technical result of the use of the invention is: enrichment of the basic diet with minerals, adsorption of heavy metals and toxic elements, as well as increasing the productivity of pigs.

According to the results of elemental analysis, feeding pigs with the natural mineral “Vodnit” can reduce the level of mineral starvation that is typical for the present. As confirmation of the possibility of implementing the invention in the form of a 3% additive in the main diet, an experiment was conducted on fattening pigs with their subsequent slaughter.

Two groups of large white breed pigs were used in the experiment. The first group was added 3% "Vodnit" of the mass of the main diet, and the second group was the control. At the end of the experiment, pigs were slaughtered, followed by the sending of meat from the longest muscle of the back (Table 2).

The content of heavy metals and toxic elements decreased compared with peers from the control group. In pig meat obtained from experimental and control groups, the quantitative content of cadmium and arsenic was less than 0.01 mg / kg The concentration of mercury in the meat of pigs of the experimental groups was below 0.005 mg / kg, which did not exceed the maximum permissible norms in food products of animal origin. In the meat of the experimental group of pigs, the lead content was lower by 16.67% compared with the meat of pigs obtained from the control group. The quantitative content of copper in the meat of pigs of the experimental group is lower by 21.43% than in meat obtained from control animals. The zinc content in meat decreased by 40.86% relative to the zinc content in meat of control animals. Therefore, the natural mineral “Vodnit” is a natural adsorbent of heavy metals and toxic elements.

Before the end of the experiment, a control blood sample was taken for biochemical analysis (Table 3). The content of calcium and phosphorus in the blood of pigs before slaughter in the experimental groups was 9.73 ± 0.56 and 7.53 ± 0.58 mg%, respectively, which is 2.75% and 3.58% more relative to the content of calcium and phosphorus in blood of pigs in the control group. Consequently, the natural mineral Vodnit is a natural source of calcium and phosphorus for the animal organism.

In addition, at the end of the experiment, a control weighing of pigs was performed, where the live weight indices exceeded those of the control group by 5.32%. Therefore, the natural mineral Vodnit is a natural supplement to increase pig productivity.
