Description

The invention relates to the field of agriculture and can be used as a biologically active additive in animal husbandry and poultry farming. Specifically, the invention consists in the extraction of coniferous woody greens with glycerin, the isolation of biologically active components and their introduction into feed as a feed additive to stabilize the energy balance of the body and increase the productivity of farm animals and poultry.

In this invention, a biologically active component, consisting of the sum of the extractives of the common green pine, is used as a feed additive. It can completely replace unbalanced vitamin preparations added to feed. The supplement contains glycerin, which is positive for optimizing the energy balance in the preparation of animal and bird rations.

The productivity of animals depends not so much on the amount of feed and concentrate they consume, but on the degree to which the animal's energy needs (organic, minerals and vitamins) are met.

For the productive healthy development of animals and birds, a whole set of biologically active substances is required daily, including vitamins, carotenoids, chlorophyll, etc.

Balancing rations can be achieved not only through the introduction of scarce components, but also with the help of feed additives that increase the efficiency of feed absorption. Biologically active preparations provide a more complete extraction of nutrients from feed, normalize the digestive system and, thus, ensure the physiological needs of the body.

Currently, there are foreign and domestic preparations and additives on the Russian market that contribute to increasing the energy value of feed. The active ingredients in these products are mainly polyhydric alcohols (glycerin, propylene glycol). Moreover, in the domestic market, the basis for energy supplements is most often propylene glycol, while in Europe glycerol is successfully used.

The main component of glycerol is glycerol (propanotriol-1, 2, 3), the simplest representative of trihydric alcohols. It is a viscous transparent liquid with a sweet taste, interacts with many compounds and is environmentally friendly, since it mixes with water in all proportions and does not pose a threat to soil and groundwater.

The use of glycerin in poultry is known as a substitute for soybean oil and other high-energy diet components, as well as its effect on broiler productivity and health. This makes it possible to use it as a potential source of energy in the diet of poultry. In addition, glycerin also plays an important role in the cellular metabolism of the body. According to the researchers, a bird of both sexes in the experimental group with a diet containing glycerin showed a gain in live weight significantly higher than in the control group [Kroupa L. Glycerol as source of energy in broiler chicken fattening / L. Kroupa, P. Suchý, E. Strakova, I. Herzig // Acta Veterinaria Brno, - 2011 .-- No.80. - P.157-164 (1)].

In feeding laying hens, medium- and high-energy rations are widely used, which leads to general obesity of the bird and fatty degeneration of the liver, decreased productivity and culling of hens. Research A.N. Negreyeva showed that with the inclusion of 3-6% glycerol in the diets of broiler chickens, the lipid content in carcases decreases. It is also noted that food glycerin, as a source of energy, is not involved in the synthesis of fat. In this regard, it seemed appropriate to study glycerin as a source of energy and a factor possibly reducing the obesity of laying hens when using high-calorie mixtures for them.

Of practical importance were studies that proved the positive effect of 1.0-1.5% glycerol additives to medium-energy and high-energy feed mixtures on the viability and productivity of layers [Matsuganov, N.F. The effect of different energy levels and glycerol supplements in laying hens rations on their productivity and egg quality: Abstract dis. Candidate of Agricultural Sciences / N.F. Matsuganov. - M.: Moscow Order of Lenin and the Order of the Red Banner of Labor Agricultural Academy named after K.A. Timiryazev, - 1979 (2)].

It is also known that water extracts are obtained from woody greens that increase the body's resistance to various diseases [RF application No. 93006909/14, A61K 35/78, 04.02.93 (3)]. The disadvantage of this product is the complexity of production, since effective extraction of water-soluble substances requires a long process, distillation of the solvent from the extract, which leads to high energy costs.

The closest analogue is the product "Premix to feed for farm animals" [RF patent No. 2456811, A23K 1/16, A23L 1/03, 08/24/2010 (4)], which contains dihydroquercetin and a filler (propylene glycol, glycerin, tween), wt. %: dihydroquercetin - 10-90%; filler - 90-10%.

The ratio of components varies over a wide range, which negatively affects the objective assessment of the effectiveness of the product "Premix to feed for farm animals" on the physiological state of the body. The disadvantage of this additive is the multi-stage production and high cost.

“Premix to feed for farm animals” has insufficiently expressed therapeutic and prophylactic effect, since it cannot affect the optimization of energy metabolism, and this leads to loss of animal productivity.

SUMMARY OF THE INVENTION

The problem to which this invention is directed, is to use in livestock coniferous energy supplements (HED) to increase the productivity of farm animals and poultry, including a wide range of biologically active substances. The developed supplement is a universal preparation in its physiological effect on the organism of farm animals.

A coniferous-energy feed additive, characterized in that it is a glycerin extract of the common green of pine, obtained by extraction of green wood at a temperature of 60-120 ° C for 3 hours with a liquid module of 1: 5, and after extraction glycerin remains in the extract .

The proposed coniferous-energy supplement has several advantages: it enriches diets with macro- and microelements, optimizes the function of the gastrointestinal tract, prevents the disease with rickets in poultry and increases its productivity.

A coniferous energy supplement is obtained by extracting green wood with glycerin, followed by isolation of the extract. The extraction is carried out in one stage at a temperature of 60-120 ° C for 3 hours with a liquid module of 1: 5. In this case, unlike traditional extractants (organic solvents and water), glycerin allows you to extract both water-soluble and lipid-soluble substances from woody greens. After extraction, glycerin does not distill from the extract, but remains in the product as a preservative and biologically active component that increases the energy value of the additive.

The use of glycerol can improve the operational properties of the resulting product. Glycerin has antibacterial properties that ensure the preservation of consumer qualities of products for a long time under normal storage conditions.

The study of the useful properties of HED was carried out under the conditions of a production experiment on laying hens in the veterinary clinic of the Agrarian Institute of the Mordovian State University named after N.P. Ogareva. "

The following examples are provided for a more detailed description of the present invention, but do not limit it in any way.

Example 1. In 2012, on the basis of the veterinary clinic of the Agrarian Institute of FSBEI HPE “Mordovian State University named after N.P. Ogareva ”studies were conducted on the use of coniferous-energy supplements in feeding poultry.

The object of the study was the laying hens of the “Lohmann Brown” cross (age 16 weeks). In the studies, 2 groups of birds (control and experimental) of 5 animals were formed. The formation of groups was carried out on the basis of analogues taking into account the origin, live weight, physiological state and age.

Poultry was fed according to the norms of feed consumption with nutrition parameters corresponding to the recommended norms of feeding VNITIP (2006). From the age of 16 weeks, the control group received the main diet, and the experimental group received the main diet with coniferous energy supplement (based on 3 g per 100 g of dry food weight). Poultry conditions were in accordance with accepted zoohygienic parameters. The duration of the experiment was 120 days.

During the experiment, the following indicators were analyzed: the safety of the repair young stock, the increase in live weight, the dynamics of the egg mass, the intensity of egg production.

The data obtained indicate a positive effect of HED on the organism of the experimental bird. High viability was found in the repair young animals of the experimental group, which in terms of the safety of the livestock exceeded the analogues from the control group by 10% (table 1).

As the results of the study showed, the use of coniferous-energy supplements in the diets had a positive effect on productivity. It was established that the inclusion of the studied HED in the diet of the experimental bird contributed to an increase in its growth rate. So, repair young animals of the experimental group at 150 days of age increased live weight by 10.4%, which is higher than that of young animals of the control group, which amounted to 9.6%.

Egg production is an inherited trait, however, its intensity is largely determined by the physiological processes of egg formation associated with environmental conditions (microclimate, keeping system, feeding).

The inclusion of coniferous-energy supplements in the diet of the bird contributed to a more intensive egg production. So, when using HED as part of diets, the egg production intensity reached 90.1% during the study period, while in the control - 48.0%.

Studies have shown that additional purification of HED from mechanical impurities by filtering can increase the effectiveness of the additive according to the main indicators with a slight increase in the cost of the product.

The technical and economic advantages of the proposed coniferous-energy supplement for livestock and poultry farming are effective in preventing the violation of energy metabolism in animals and birds. The diet enriched with HED provides a stable and intensive growth of repair young animals. The use of coniferous-energy supplements contributed to an increase in egg production and an improvement in morphological parameters and egg quality.
