Description

The invention relates to the field of agriculture and can be used as a biologically active feed additive in animal husbandry and poultry farming. Specifically, the invention includes the extraction of biologically active substances of green wood with glycerin and their introduction into feeds as a feed additive containing nutrients to stabilize the energy balance of the body and increase the productivity of farm animals.

Recently, the issue of the integrated use of all forest biomass has been sharply raised. A huge potential in this could be the production of biologically active substances from coniferous woody greenery.

In this invention, a biologically active ingredient from the sum of the extractives — the woody green of Scots pine (Pinus sylvestris L.) —is used as a feed additive. It can completely replace the vitamin preparations added to the feed, unbalanced in vitamins. The supplement contains glycerin, which can be successfully used in the preparation of animal and poultry rations to optimize the energy balance of rations. This eliminates the use of drugs obtained by chemical synthesis.

The productivity of animals does not so much depend on the amount of hay, haylage, silage, concentrates, etc. they consume, but on the degree to which the animal's needs for energy, organic, minerals and vitamins are satisfied.

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. Such biologically active preparations provide a more complete extraction of nutrients from existing feeds, normalize the digestive system and, thus, ensure the physiological needs of the body at minimum cost for feed.

The milk production of cows varies significantly during lactation. After calving, the daily milk yield increases and reaches a maximum at the 2-3rd month, and then gradually decreases. The nature of the lactation curve depends on the individual characteristics of the animal, feeding conditions and content [Kathakov P. Lactation curves depending on the level of feeding of heifers // Dairy and beef cattle breeding. - 1991. - No. 3. - p.12-14. (1)].

As a rule, at the beginning of lactation, cows often have a significant energy deficit, which can lead to serious metabolic disturbances. This is due to the fact that milk yield increases faster than energy comes from the feed. The cow begins to use its own reserves and in the first 80-110 days after calving, it can lose 10-12% of live weight [Savchenko S. Organization of full-value feeding of cows / S. Savchenko, D. Drozhzhachikh, P. Savchenko // Dairy and beef cattle breeding. - 2006. - No. 2. - p.22-24. (2)].

The first 100 days after calving should be used for milking cows. Under the dough, we understand the implementation of a number of measures aimed at increasing the milk productivity of cows and first-calf heifers, these activities include: organizing proper feeding, using proper milking, creating good living conditions [Norms and diets for feeding farm animals. Reference manual. 3rd edition revised and expanded. / Ed. A.P. Kalashnikov, V.I. Fisinina, V.V. Shcheglova, N.I. Kleimenov. - Moscow. 2003 .-- 456 p. A.P. Kalashnikov, 2003 (3)].

In the transit period (20 days before calving and 20 days after), special attention is paid not only to cicatricial digestion and liver, but also to monitor the state of the immune system. The body's immune reactivity during the hotel period is very limited. In this case, an animal blood test shows a decrease in vitamins A, E, β-carotene. A special cottage feed with a high content of vitamins A, E, β-carotene can compensate for this deficiency. Such substances include processed products of coniferous herbs. Woody greens (needles, leaves, bark, wood) are rich in essential oils (terpene hydrocarbons), carotenoids (carotenes and xanthophylls), green pigments (chlorophyll “a” and “b”), vitamins (provitamin A, vitamins E, K, D , F), volatile and other biologically active substances.

The main technique for increasing productivity after calving is to advance nutrients and energy to increase milk yield.

In practice, concentrates are often used as the main source of energy increase in the diet. However, in this case, the concentration of fiber in the rumen becomes lower than the permissible, which results in a change in the normal ratio of acetic, propionic and butyric acids in the direction of increasing the proportion of the last two. In turn, when animals consume a large amount of protein, energy costs increase, since 5450 Kcal of energy is used per 1 kg of nitrogen excreted in the urine in the form of urea. There is a vicious circle: they try to satisfy the high nutrient demand of highly productive cows by feeding an increased amount of concentrated feed, and this leads to additional energy costs, its deficiency and the development of ketosis.

The introduction into the diet of a cow after calving of power engineers, sources of “protected” proteins and fats makes it possible to obtain an additional 4 liters of milk per day in the first lactation period. In the first month or two after calving, the cows must be fed with a special diet with a net energy concentration of at least 7.0 MJ per 1 kg of SV diet, but with a protein restriction of 16%. During this period, it is appropriate to feed protected fats, glycerol [Ivanov A. 20-0-20 Optimum balance in feeding cows. "Transit" period. The path of perfection // Pricer, - 2010. - No. 10. - p.31-32. (four)].

Currently, there are foreign and domestic drugs on the market that contribute to increasing energy in the diet. The active ingredients in these products are mainly polyhydric alcohols (glycerin, propylene glycol).

The principle of action of these drugs is based on maintaining and increasing the level of glucose in the blood of lactating animals and, accordingly, reducing the energy deficit, which prevents the development of ketosis, leads to an increase in milk yield, the content of fat and protein in milk, and prevents weight loss. 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 (1,2,3-propanotriol) - the simplest representative of trihydric alcohols. It is a viscous transparent liquid with a sweet taste, interacts with many compounds and is environmentally friendly, because it decomposes quickly and does not pose a threat to soil and groundwater. It is for these reasons that it can be used in animal nutrition as an energy supplement.

The use of glycerin in poultry is known as a substitute for soybean oil and other high-energy diet components, and a study is made of the effect of glycerol on broiler productivity and health indicators. Currently, a large amount of glycerin is available on the world market, which 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 an increase in live weight significantly higher than in the control group. The weight of the bird in the control group was 2.078 kg, while the average weight of chickens in the experimental group was 2.341 kg. Feed conversion in broilers of the experimental group was better, amounted to 1.81 kg compared to 1.84 kg in the control. From the results of the study it follows that the optimal amount of glycerin in the diets of poultry feed is 5% of the total diet [Kroupa L, Glycerol as source of energy in broiler chicken fattening / L. Kroupa, P. Suchy, E. Strukova, I. Herzig // Acta Veterinaria Brno, - 2011 .-- No.80. - p. 157-164 (5)].

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. Studies by A.N. Negreeva (1974) 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 that possibly reduces the obesity of laying hens when using high-calorie mixtures for them. The obtained experimental materials showed high efficiency of using feed mixtures with lowered (1089 kJ / 100 g) levels of exchange energy and crude protein (14%) compared to the recommended norms. Of practical importance were the results of the study, which proved a positive effect on the viability and productivity of laying hens 1, and 1.5% glycerol additives to medium-energy and high-energy feed mixtures [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. (6)].

Known vitamin supplement containing vitamins A, D, E, trace elements and bran as a filler [Premixes for repair heifers. Compound feed, feed additives and milk replacer for animals // Reference. M., VO Agropromizdat, 1990, p. 64 (7)]. The use of bran as a filler leads to the instability of the additive, which is prone to caking.

It is also known that now 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 (8)]. 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 an increase in energy consumption.

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 (9)]. This premix for farm animals contains dihydroquercetin and an excipient selected from the group comprising propylene glycol, glycerin, tween, in the following ratio of components, 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 its multicomponent, multi-stage and high cost of the process.

The raw material for the production of the additive “Premix to feed for farm animals” is dihydroquercetin. Dihydroquercetin - a flavonoid obtained from Siberian larch wood; Siberian larch wood has a limited localization of production, which is essential for the European part of Russia, in contrast to the raw materials we claimed - the common green of pine, which is ubiquitous. In addition, one of the components of the additive declared by us is not expensive wood, but waste from forest processing, that is, woody greens. Also, the production of dihydroquercetin involves extraction in an organic solvent, separation and filtration, in addition, the need for separation of the extracts leads to an extended production cycle (1-2 days), a low degree of purification, since there is no promising technology for this production; production is low environmental due to emissions of organic solvents into the atmosphere.

“Premix to feed for farm animals” has insufficiently expressed therapeutic and prophylactic effect, since there is a significant imbalance in the introduction of biologically active substances in the regulation of redox processes, metabolism and energy in the body. Despite the complex biochemical composition, the product 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-glycerin biologically active additives to increase the productivity of farm animals and poultry, including a wide range of biologically active substances. The developed supplement is a cheap and versatile drug in terms of its physiological effect on the body of farm animals.

Coniferous-glycerin biologically active additive contains coniferous extract of green wood of pine ordinary, extracted with glycerin at a temperature of 60-120 ° C with a liquid module of 1: 3-1: 10.

The following ratios of woody greens and glycerin were investigated: (1: 3), (1: 5), (1: 7), (1:10), respectively. In the course of experimental studies in experimental animals, the optimal ratio of the components of the inventive coniferous-glycerin dietary supplement was established.

A distinctive feature of the claimed invention is the quantitative composition of conifer-glycerin biologically active additives, namely the use of woody greens and glycerin in a ratio of 1: 5, respectively.

The proposed coniferous-glycerin dietary supplement has a number of significant advantages: it enriches diets with macro- and microelements, increases the efficiency of the use of nutrients in feeds with a high level of energy and protein, optimizes the function of the gastrointestinal tract, prevents rickets in birds and increases its productivity, prevents the development of ketosis leads to an increase in milk yield, the content of fat and protein in milk, and prevents weight loss in lactating polyastric animals.

Extraction of the coniferous extract of pine wood with ordinary glycerin will prevent metabolic disturbances in the animal’s body, support the normal functioning of the enzymatic system of the body, ensure the immunobiological activity of the body and increase the productivity of farm animals and poultry.

The close interaction of vitamins and other biologically active substances of woody greens on a number of metabolic profile indicators showed the identification of a positive effect of preservation, growth stimulation, increase in live weight of poultry and lactating cows.

The technical result of the claimed invention is a complex feed additive from plant materials, which can exhibit both adaptogen properties and general properties due to the interaction of components, as well as having the ability to make up for vitamin deficiency.

Coniferous-glycerin dietary supplement is obtained by extracting biologically active substances of woody greens with glycerin and isolating the extract. The extraction is carried out in one stage at a temperature of 60-120 ° C for 2-10 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 biologically active component and preservative.

Coniferous-glycerin dietary supplement based on the proposed compositions has new properties:

- increased productivity in farm birds (laying hens) and cows during lactation;

- increased secretory-motor function of the gastrointestinal tract;

- chemical neutrality with respect to the contacting parts of the metering devices and animal feeders;

- the absence of toxic effects at appropriate doses.

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 simple storage conditions.

The study of the beneficial properties of coniferous-glycerin biologically active additives 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 NP Ogareva "and on the cows of the experimental farm of the Agrarian Institute of FSBEI HPE" Mordovian State University named after N.P. Ogareva ".

The following examples are used to describe the present invention in more detail, but are not limited 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 NP Ogareva "studies were conducted on the use of coniferous-glycerin biologically active additives in feeding poultry.

The object of the study was the laying hens of the “Lohmann Brown” cross. In the studies, 5 bird groups (control and 4 experimental) were formed with 7 animals each according to the scheme presented in table 1. The groups were formed according to the principle of analogues taking into account origin, live weight, physiological condition and age.

Table 1 Research design Group The number of goals in the group Age at the beginning of the experiment, weeks Feeding Features Control 7 16 The main diet (O.R.) 1st experienced 7 16 O.

P + conifer-glycerin additive (1: 7); 3 g per 100 g of feed 4th experienced 7 16 O.R. + coniferous-glycerin (1: 3); 3 g per 100 g of feed

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 additionally different levels of coniferous-glycerin biologically active additives. Poultry conditions were in accordance with accepted zoohygienic parameters. The duration of the experiment was 120 days.

The control group received a main diet (RR) free of conifer-glycerin biologically active additives. In addition to the main diet, repair young animals of the 1st experimental group received a coniferous-glycerin biologically active additive of the component composition: wood greens: glycerin - 1: 3, based on 3 g per 100 g of dry feed mass; In addition to the main diet, the experimental group 2 received the main diet and coniferous-glycerin biologically active additive of the component composition: wood greens: glycerin - 1: 5, based on 3 g per 100 g of dry feed mass; youngsters of the 3th experimental group received the main diet and coniferous-glycerin biologically active additive of the component composition wood greens: glycerin - 1: 7, at the rate of 3 g per 100 g of dry feed mass; young 4 experimental group received the main diet and coniferous-glycerin biologically active additive component composition: wood greens: glycerin - 1:10, at the rate of 3 g per 100 g of dry food mass.

During the experiment, the following indicators were analyzed: the safety of young stocks, the gain in live weight, the dynamics of the egg mass, the intensity of egg production, morphological indicators of egg quality and the distribution of eggs into categories.

The data obtained indicate a positive effect of coniferous-glycerin biologically active additives on the organism of experimental birds. High viability was found in the repair young stocks of the 2nd experimental group (coniferous-glycerin biologically active additive of component composition: woody greens: glycerin -1: 5; 3 g per 100 g of feed), which in terms of the safety of the livestock exceeded the analogues from the control group by 10% (table 2).

As the results of a study of an experimental bird showed, the use of coniferous-glycerin biologically active additives in the diets had a positive effect on productivity. It was found that the inclusion of the studied supplement in the diets of experimental birds contributed to an increase in its growth rate. So, repair young animals of the 2nd experimental group from daily to 150 days of age increased their live weight by 1603 g, which is 10.6% and 7.1% higher than that of young animals of the control and 1 experimental groups and also by 2.2% and 3.5% higher than in young animals of groups 3 and 4, respectively. For the entire period of the experiment, the average daily growth in poultry of the 2nd experimental group reached 10.68 g, which is 10.67% higher than the control group

Growth indicators of live weight indicate a positive effect of coniferous-glycerin biologically active additives with a component composition: woody greens: glycerin - 1: 5 compared with other versions of the component composition of the additive.

It was established that the most effective use of feed was in poultry of 2 experimental groups. The best productive indicators of poultry of the 2nd experimental group are due to more efficient assimilation of nutrients from coniferous biologically active additives and the optimal dosage of glycerin.

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).

Based on the studied data (table 3), it can be seen that with age, egg production of laying hens increases in all experimental groups. The inclusion in the diet of poultry coniferous-glycerin biologically active additives contributed to a more intense egg production. So, when we use additives we studied with a component composition: wood greens: glycerin - 1: 5, in the composition of the diets the egg production intensity reached 90.1% during the study period, and in the control - 48.0%.

Table 3 The intensity of egg production,% Age weeks Groups control 1 experienced 2 experienced 3 experienced 4 experienced 21 11,4 10,2 8.2 8.9 10.1 22 17.4 11.1 27.5 12,2 23.5 23 33.7 12,2 40.8 20.6 21.6 24 43.5 22.4 44.9 25.7 45.9 25 37,4 33.7 42.9 27.9 44.7 26 33.6 32,7 67.3 44.6 56.8 27 42.8 28.6 65.3 43.5 51.0 28 45.7 38.8 83.7 63.7 65.5 29th 45.8 48.6 89.9 68.5 67.5 thirty 48.0 68.3 90.1 72.5 74.6

The second most important breeding trait, which has the greatest economic value in the production of egg products, is the mass of eggs.

With the same egg production, the amount of total egg mass is different, which is reflected in the output of egg production and its value.

Thus, the average egg mass of laying hens of the control group of the 21-week-old at the age was 43.7 g, and in the 30-week-old - 56.30 g, which is 28.83% more. It should be noted that during the experiment, a positive dynamics in the growth of egg mass in the experimental bird was revealed, but at the same time, certain differences in egg mass were established, which are related to both age and the level of biologically active additives in the diets. Feeding of laying hens according to diets containing coniferous-glycerin biologically active additive with component composition: woody greens: glycerin -1: 5 provided an increase in the mass of eggs at the age of 21 weeks by 5.3% and 3.9%; 25 weeks of age 11.2% and 9.2%; 30-week at 8.1% and 1.8% compared with the control and 3 experimental groups, respectively.

Feeding a coniferous-glycerin dietary supplement to a bird had a significant effect on obtaining eggs with an optimal shape index (75.0-76.7%), (table 4).

The thickness of the shell determines its strength and ranges from 200 to 600 microns. The strength of the shell is considered satisfactory with a thickness of 320 microns or more. With a shell thickness of 310 microns, the proportion of battle and notch is 21.8%; 360 μm 6.8%. Based on objective data, the highest shell thickness was detected in 2 experimental groups, which is 3.6 microns more than in the control.

The additional inclusion in the diet of laying hens of coniferous-glycerin biologically active additives with the component composition: woody greens: glycerin - 1: 5 ensured the production of eggs for the period of the experiment of the highest category 1.4%, selected 2.4%, the first 45.8%, the second 41.7% and the third 8.7%, which is confirmed by the data presented in table 5.

Based on the results of studying the use of coniferous-glycerin biologically active additives in the feeding of experimental birds, it seems possible to draw the following conclusions:

1. The diet enriched with coniferous-glycerin biologically active additive provides stable and intensive growth of repair young animals.

2. Among the tested variants of the additive, the most effective was the coniferous-glycerin biologically active additive with the component composition: woody greens: glycerin - 1: 5.

3. The use of coniferous-glycerin biologically active additives with a component composition: woody greens: glycerin - 1: 5 contributed to an increase in egg production by 53.3%, egg weight by 4.5 g, an improvement in morphological parameters and egg quality.

Example 2. In 2012, a scientific experiment was conducted in the experimental farm of the Agrarian Institute of the Mordovian State University named after N.P. Ogareva ". The aim of the work was to obtain scientific data on the use of coniferous-glycerin biologically active additives in feeding dairy cows.

The object of the study were cows 2-3 lactation. In the studies, 5 groups of animals (control and 4 experimental) were formed, 5 animals each, according to the scheme presented in table 6. The groups were formed according to the principle of analogues taking into account origin, live weight, physiological condition and age.

Feeding animals was carried out in accordance with the detailed norms of feeding farm animals developed by A.P. Kalashnikov, N.I. Kleimenov and others (2003).

Table 6 Research design Group The number of goals in the group Feeding Features Control 5 The main diet (O.R.) 1st experienced 5 O. P + coniferous-glycerin (1: 3); 22 g / goal / day 2nd experienced 5 O.R. + coniferous-glycerin (1: 5); 22 g / goal / day 3rd experienced 5 O. P + conifer-glycerin additive (1: 7); 22 g / goal / day 4th experienced 5 O.R. + coniferous-glycerin (1: 3); 22 g / goal / day

In the experiment, the cows of the control group received an economic ration; 1 experimental group - an economic diet along with coniferous-glycerin biologically active additive of component composition: woody greens: glycerin - 1: 3 in the amount of 22 g / head / day; 2 experimental groups - an economic diet along with coniferous-glycerin biologically active additive of component composition: woody greens: glycerin - 1: 5 in the amount of 22 g / head / day; animals of the 3 experimental group received the main diet and coniferous-glycerin biologically active additive of the component composition wood greens: glycerin - 1: 7 in the amount of 22 g / head / day; animals of the 4th experimental group received the main diet and coniferous-glycerin biologically active additive of the component composition woody greens: glycerin - 1:10 in the amount of 22 g / head / day.

Test duration: 1 week before the predicted calving day and the first 70 days of lactation.

Cow productivity in the first 80 days of lactation is shown in table 7.

Table 7 Cow Productivity Indicators Groups control 1 experienced 2 experienced 3 experienced 4 experienced Dry matter consumption, kg 14.2 14.7 15.3 15.0 14.8 Milk yield, kg 35.7 36.1 38,2 37.7 37.5 The fat content in milk,% 3.6 3,5 3.9 3.8 4.2

As can be seen from the production indicators shown in table 7, the most effective was the addition of the component composition: woody greens: glycerin - 1: 5 in the amount of 22 g / head / day, fed to experimental group 2, although the highest milk fat content was found in group 4 (additive component composition: woody greens: glycerin - 1:10 in the amount of 22 g / goal / day), which is explained by the increased content of glycerin in the additive, but depressed milk production.

As a result of our studies of the peripheral blood of the experimental and control groups of cows, an increase in the hemoglobin level in the blood of experimental animals was established, which was a consequence of the activation of the metabolic processes of the body. The additive in the studied doses did not adversely affect the morphological and biochemical composition of the blood of animals, it stimulated the hematopoiesis process: the number of red blood cells in the experimental groups increased by 1.1-3%, hemoglobin by 11-17%. Feeding the additive contributed to a decrease in the amount of urea by an average of 18.2%, which indicates a positive effect of the additive on the functioning of the liver. The general morphological composition of the blood is within the physiological norm.

Based on the results of studying the use of coniferous-glycerin biologically active additives in the feeding of dairy cows, it seems possible to draw the following conclusions:

- coniferous-glycerin biologically active additive had a significant effect on milk yield of cows;

- feeding supplements of all formulations increased the level of feed intake in cows;

- the use of coniferous-glycerin biologically active additives of component composition: wood greens: glycerin - 1: 5 in an amount of 22 g / head / day in the framework of this test led to the economic efficiency of the application.

The technical and economic advantages of the proposed coniferous-glycerin biologically active additives for livestock and poultry farming are to effectively prevent disturbances in energy metabolism in animals and birds. When using coniferous-glycerin biologically active additives in farm animals and poultry, the general condition improves, the safety of the livestock, as well as qualitative and quantitative signs of productivity, increase.
