Description

The invention relates to the field of agriculture, namely to the production of humic biologically active feed additives, including macro-, microelements. The additive is intended for polygastric animals (cattle, sheep, goats) at different age and physiological periods for carrying out preventive measures aimed at improving the productive qualities of animals and eliminating iodine deficiency, which is characteristic almost everywhere for animal diets.

The use of humic preparations as a feed additive is known. Studies have shown that the introduction of humic acids in the diet of animals leads to an increase in milk productivity and fat content of cow's milk. Humic acids improve feed utilization, reduce their costs. Humates have a general stimulating effect on the animal organism and are harmless at the same time. Humates enhance the antitoxic function of the liver, phagocytic ability and serum lysozyme activity. They enhance the body's resistance to stress, infections and increase growth of young animals [V.A. Terentyev “The probable mechanism of action of humic acids on living cells”. Abstracts of the report of the All-Russian conference “Humic fertilizers”, 02.16.2001. - Ryazan, 2001. - P.38].

The problem of iodine deficiency for livestock is currently one of the most pressing. This is due to the fact that the iodine content in the soil, water and, as a result, in feed is low. It is known to use iodine salt for animal feed as part of premixes, for example, 350 g of iodine are introduced per 1 ton of premix of 1% grade P-60-3 produced in the Novosibirsk region. With a dose of 100 g premix per head per day, the animal receives 0.007 g of iodine. A higher iodine content in the premix is unacceptable due to negative manifestations associated with an increased intake of iodine in the thyroid gland from mineral sources of the trace element. When calculating the balance of this element in the diets of highly productive cattle, its deficit from 60 to 62% was noted. As a result, among non-infectious pathology of cattle, endemic goiter occupies one of the first places [Tsyb A.F., Roziev R.A., Goncharova A.Ya., Grigoryev A.N., Skvortsov V.G., Bozadzhiev L. L., Podgorodnichenko V.K., Tomchani O.V. Functional suitability of iodine casein for the prevention of iodine deficiency. - Bulletin of the Russian Academy of Medical Sciences. - 2001. - No. 6. - S.17-21].

Humic feed additives contain not only humic acids and fulvic acids, but are also rich in various vitamins, macro- and microelements, which are vital for the growth, development of animals, and the formation of milk productivity. But it should be noted that the iodine content in them is so insignificant that the problem of iodine deficiency in animals when feeding humic fertilizing is not removed.

It is known that iodine, necessary for the implementation of metabolic processes, is one of the most important trace elements that regulate the speed and intensity of redox reactions. Iodine is involved in the production of thyroid hormones, indirectly affects the metabolism. The lack of this element leads to the lag of young animals in growth and development, general lethargy of the animal, decreased productivity, infertility of females and males, impaired blood circulation. Iodine deficiency leads to significant economic damage, which is determined by the death of the embryos, the birth of a dead and weak offspring, barrenness and a decrease in milk yield in cows, a decrease in the immune status in animals, and as a result, a high rejection from the herd, and a slowdown in young growth.

The importance and irreplaceability of iodine for the normal development and functioning of animals encourages the artificial enrichment of feed with this trace element.

Known feed additive based on the mother liquor of sodium humate, which contains iodine - 0.12 mg / l: (RU 2248131, publ. 2005).

A disadvantage of the known feed additive is its low iodine content: 0.12 mg / l of a mother liquor containing 3.6% humic acids. Moreover, the mother liquor of sodium humate with a concentration of 2.5 - 3% is introduced into the diet of any animals at the rate of 0.1-0.45 ml per 1 kg of live weight once a day. For a calf weighing 30 kg, the dose of iodine consumed by the calf per day is 0.00036-0.00135 mg, which is quite insufficient. With the prevailing type of feeding of young animals during the milky period of cultivation, the prophylactic daily dose of additional iodine can be an average of 4-4.5 μg per kg of live weight. In terms of, this means that with the introduction of the daily norm of a feed additive not enriched with iodine, iodine deficiency can be eliminated by only 0.92%.

The prototype is a method of producing a humic feed additive from peat known from RU 2380902, publ. 02/10/2010 obtained by alkaline hydrolysis of lowland peat with an aqueous solution of ammonia in the presence of hydrogen peroxide. A solution of humic feed additive obtained by diluting the mother liquor of humic feed additive to a humic acid content of 10,000 mg / l is added to the piglets ’diet, and an adaptation dose of 0.1 ml per kg live weight per day is introduced on the first day, and starting from the third days - at a dose of 0.5-0.7 ml per kg of live weight once a day.

A disadvantage of the known method for producing a humic feed additive is that it cannot solve the problem of iodine deficiency in animals.

The invention is aimed at creating a method for producing a feed additive from peat for the prevention and treatment of iodine deficiency in polygastric animals, as well as at increasing the profitability of milk production.

The technical result aimed at solving the problem is to eliminate the above disadvantages due to the fact that iodine salt is additionally added to the claimed preparation.

The problem is also solved by the fact that a method for producing a humic feed additive from peat for polygastric animals is proposed, which consists in alkaline hydrolysis of lowland peat with an aqueous solution of ammonia in the presence of hydrogen peroxide during heating and in the subsequent separation of the liquid phase.

What is new is that the resulting mother liquor humic solution is mixed with an aqueous solution of potassium iodide based on the preparation of the final product containing 1% humic acids and 0.0109-0.0163% potassium iodide, including 0.008-0.012% iodide ion.

Alkaline hydrolysis of lowland peat with an aqueous solution of ammonia in the presence of hydrogen peroxide is carried out by heating in the temperature range from 110 ° C to 140 ° C.

In addition, the content of humic acids in the mother liquor is not less than 45,000 mg / l at an alkaline pH of 8-9.

The resulting mother liquor humic solution is diluted with distilled water to a concentration of 1.25%, and potassium iodide is dissolved to a concentration of 0.0545-0.0815%, including 0.04-0.06% iodide ion, and then these solutions are mixed in a volume ratio of 4: 1.

In this case, the obtained humic solution is mixed with an aqueous solution of potassium iodide at room temperature.

If necessary, the liquid phase is dried to obtain a dry residue.

The inventive humic feed additive, like the well-known feed additive, includes humic acids.

New is that it additionally contains potassium iodide.

Moreover, the additive contains 1% humic acids and 0.0109-0.0163% potassium iodide, including 0.008-0.012% iodide ion.

The problem is also solved by the fact that the proposed method of feeding the claimed humic feed additive, which consists in the fact that the claimed additive is used at a dose of 1 ml per 10 kg of live weight of the animal per day.

The concentration of the element in the preparation is designed to completely eliminate its deficiency when evaporated at the proposed dosage. The drug can be used as a means of prevention:

- endemic goiter of cattle;

- hypofunction of the thyroid gland;

- metabolic disorders of carbohydrates, proteins and fats;

- the birth of a dead offspring.

Iodine contributes to better digestibility of feed proteins, the deposition of calcium and phosphorus in bone tissue.

When developing the drug, we used the unique opportunity of Humiton - to form chelate complexes with trace elements.

Humic acids of the drug Humiton stabilize the intestinal flora, and as a result, contribute to better absorption of iodine, therefore the drug is the most effective form of enriching the body with this trace element.

The use of organic iodine compounds is known, which are less toxic than mineral salts. In a chelate (organic) compound, iodine is bound to a protein or amino acid and is absorbed by the body only with an element deficiency [RU 2248131 C1, 2005; RU 2349094 C1, 2009]. Therefore, organic compounds of animals cannot be practically poisoned, and the element is more effectively consumed [Friedberg W., Reineke E.P. Metabolism of Iodinated Casein in the Rat // Am. J. of Physiology. - 1956. - V.185. - P.27-30 .; Reineke E.P. The thyroxine content of thyroactive iodinated proteins as determined by a radioactive isotope dilution technique / J. of Dairy Science. - 1954. - V.XXXVIL - P.1227-1232.]. As an organic component in the claimed invention uses a humic feed additive from peat, which reduces the toxic effect of mineral and organic substances [Prospects for the use of peat and its processed products in animal husbandry-Tomsk: TPU Publishing House, 2006. - S.29-56].

The content of humic acids in the mother liquor of at least 45,000 mg / l is due to the maximum yield of humic acids from peat during alkaline hydrolysis.

In this case, potassium iodide is used in an amount of 109-163 mg / l, including 80-120 mg / l of iodide ion. The amount of iodine introduced is justified by calculations of the balance of this element in animal diets. A dose of less than 109 mg / l will not provide the daily requirement of the body for the element, and more than 163 mg / l can lead to hyperteriosis.

A method of obtaining a humic feed additive is that the resulting mother liquor of humic solution is mixed with an aqueous solution of potassium iodide based on the final product containing 1% humic acids and 0.0109-0.0163% potassium iodide, including 0.008-0.012% iodide ion.

It is advisable to dilute the uterine humic solution with distilled water to a concentration of 1.25%, and dissolve potassium iodide in water to a concentration of 0.04-0.06%. When mixing these two solutions in a volume ratio of 4: 1, a solution with the stated quantitative content of the components is obtained.

The method of obtaining the organic component of the inventive additives is carried out by heating in the temperature range from 110 ° C to 140 ° C. This temperature range provides maximum extraction of humic acids from peat.

It is advisable to mix the resulting mother liquor humic solution with an aqueous solution of potassium iodide at room temperature to avoid loss of iodine.

The amount of supplementation for a cow with a live weight of 500 kg requires 50 ml of the drug (at a dose of 1 ml per 10 kg of live weight of the animal per day), which will contain 4-6 mg of iodine for this animal, depending on productivity 36-55% of daily requirements, the remaining amount of iodine the animal consumes from the main feed of the diet.

The invention is illustrated by the data presented in figures 1-4.

Figure 1 shows the dynamics of the protein level when feeding the inventive humic feed additive from peat, enriched with iodine.

Figure 2 shows the change in the level of calcium in the blood serum of experimental animals during the study period.

Figure 3 presents the dynamics of milk productivity

The resulting mixture was heated to 140 ° C with constant stirring and the liquid phase was separated. The liquid phase, which is a concentrated mother liquor, contains at least 45,000 mg / l of humic acids.

Example 4

For scientific and economic experience, a feed additive was used. Enriched with iodine, obtained according to example 2. The experiment was conducted in a breeding plant of Dubrovskoye CJSC in the Kozhevnikovsky District of the Tomsk Region on pure-bred cows of black-motley (Holstein) breed. For the experiment, two groups of animals were formed by the method of pairs - analogues, the formation of the groups was carried out according to the following indicators: age, live weight, origin, milk productivity of cows for the previous lactation, prevailing daily productivity at the beginning of the experiment, physiological condition (from 50 to 100 day two lactation, all cows were pregnant). From a livestock of 860 cows, two groups of ten animals each were formed according to the listed indicators. Before being tested, animals were examined and found to be conditionally healthy.

The conditions of keeping and feeding the experimental and control animals were identical, except for the studied factor — the control group was fed with potassium iodide in the amount necessary to eliminate iodine deficiency - 15 mg per head per day, experimental 50 ml of the claimed humic feed additive from peat containing 5, 43 mg of iodine salt (4 mg of iodide ion). The need for feed and nutrients was calculated on the basis of the norms and diets recommended by the Agricultural Academy [Kalashnikov AP, 1985], RAAS [Kalashnikov AP et al., 1995], by productivity, live weight and physiological state.

The duration of the experiment was 18 days.

Analyzing table 1, it should be noted that a slight decrease in the level of carotene in serum is associated with the process of crushing cows and is typical for lactating animals in the production cycle of milking. An increase in alkaline reserve indicates the normalization of acid-base balance in the body of newborn cows.

In cows of the experimental group, calcium deficiency was noted. At the time of the experiment, the calcium deficiency amounted to 18.7% of the lower limit of the physiological norm for cattle in the dairy direction of productivity, for 18 days of observation, this indicator decreased to 5.9%. When using the diet of the inventive humic feed additive from peat enriched with iodine, the calcium content in the blood serum of experimental animals stabilized and increased by 12.8% (table 2).

The protein level in the experimental group was higher compared with the indices in animals of the control group, this is directly correlated with milk productivity. In animals with a higher daily milk yield, the level of protein in the blood serum before milking (for 60 minutes) is always higher (Fig. 1).

The use of iodine-containing humic feed additives from peat not only eliminates iodine deficiency in the animal body, but also normalizes the calcium content in the blood, which favorably affects the health of animals (figure 2).

The results of the experiment showed that the introduction of a humic feed additive containing potassium iodide into the diet of the experimental group of cows provided an increase in the content of blood protein by 0.22%, calcium by 1.22% and reserve alkalinity by 0.9 units. The remaining indicators remained at the level of the experimental option at the beginning of the experiment.

Table 3 presents the average milk yield, including milk yield in terms of 3.4% fat, the content of fat, milk fat and protein at the beginning and end of the experiment. The difference in productivity between the starting period and at the end of the studies was significant in the groups.

With insufficient intake of iodine, protein synthesis is primarily suppressed and, as a result, the milk productivity of cows is reduced. The group fed the inventive humic peat feed supplement enriched with iodine exceeded the control milk production, receiving potassium iodide as the source of this trace element.

During the experiment, a significant increase in milk fat content (P> 0.99) was found in the group receiving the claimed humic feed additive from peat enriched with iodine, which suggests that it is a stimulator of scar microbiocenosis and contributes to better digestibility of the feed. As a result, the biosynthesis of volatile fatty acids, which precede the synthesis of milk fat, is enhanced. At the same time, it should be noted that, in addition to using the ministad method, both experimental groups were compared with the average control milkings of the rest of the livestock (twice per study). The control and experimental groups exceeded the herd at the beginning of research by 2.2 and 3.2 kg, respectively (completion of milking), and at the end of research by 2.7 and 3.9 kg, which indicates the exceptional role of this element, fed as mineral salt, and in the organic complex.

Table 4 presents the economic efficiency of using a humic feed additive from peat enriched with iodine, in comparison with the group that received potassium iodide.

The results of the experiment showed that due to the use of a humic feed additive containing potassium iodide, they showed an increase in milk yield of natural fat by 1.56 kg per day, milk yield in terms of basic fat content by 2.87 liters per day. Milk fat increased by 0.14%, milk fat - by 0.98 kg, protein content - by 0.1%.

An increase in the milk productivity of the experimental group was noted by 14.06% compared with the control group (milk in terms of basic fat content) and by 10.27% in comparison with the productivity of experimental animals at the beginning of the experiment. There was a significant change in the fat content of milk: by 0.14% (P <0.05).

The economic efficiency of feeding a humic feed additive from peat enriched with iodine in the diets of lactating animals was calculated only by the difference in milk productivity and drug costs (Table 4).

As a result of the studies, the effect of a humic feed additive from peat enriched with iodine on the milk productivity of lactating animals was established. When feeding a humic feed additive from peat enriched with iodine (with an iodine concentration of 200 mg / kg, 55% of which is in the chelate complex) at a dose of 1 mg per 10 kg of live weight:

- increased milk productivity by 9.72% compared with the control group of animals fed with potassium iodide;

- increased fat content of milk by 0.14% (P> 0.99);

- the health status of animals has improved, as evidence, the content of calcium in the blood serum of experimental animals has increased by 12.8%;

- the profitability of milk production increased by 3.04%.
