The invention relates to agriculture, in particular to the preparation of feed from plant products.

Set that to increase the biological value and productive feed in the poultry industry must be enriched with biologically active substances. It is important use for the enrichment of natural plant sources of biologically active substances, which greatly improves the environmental quality of products.

A method of obtaining grass meal, which includes grinding the green mass of plants, its drying in a drum dryer in a stream of hot air (type AVM-0,5; 1,5) and then granulating the dried mass (Brody NM, Kondratov A.F., Zener A.G., khadanovich M.A. Technology feed preparation. Novosibirsk: the West Siberian publishing house, 1975. S.).

However, in this way to obtain herbal flour product obtained contains a large amount of fiber. In addition, because of differences in moisture content in stem and leaf fractions difficult to choose the optimal drying temperature. Thus, when the temperature of drying high residual humidity stems leads to the development of putrefactive processes in the stern. Increasing the temperature results in the combustion of leaf mass, which reduces the quality of herbal torment is by reducing the content of protein and carotene.

A method of producing extruded feed of green mass, including high-temperature drying grass cutting with subsequent separation of the pile on listlevel and stableboy faction and pressing, with the aim of improving forage quality while reducing energy consumption, drying grass cutting produce up to 30-35% moisture, separated stableboy faction finally dried to a moisture content of 15-18%, after which it is mixed with littleboy fraction (A.S. USSR №1384308, 30.03.1988,, class. And 23 To 1/20, bull. No. 12).

However, in a known way to obtain herbal flour impossible to reduce the fiber content, as after drying to produce a mix of both factions of the green mass. In addition, reducing the moisture content of green mass before separation up to 30-35% may lead to loss of protein and carotene.

The closest analogue is a method for preparing a granular protein-vitamin feed supplements based on green plants, including the drying of green plants in the drying chamber to a residual moisture content, mixing with dry desiccant, grinding and granulating, and simultaneously pulled to a moisture content of 65-72% green plants in the drying chamber serves the seeds of leguminous plants with humidity of 35-60% and in a ratio of 3:1-1:3, respectively on dry substance. Dried sertraline raw material to a residual humidity is 18-24%. Mixed raw materials with dry desiccant - meal sunflower and fodder yeast in the amount of 15-35% by weight of the mixture. In the process of granulation is added to the mixture of green protein concentrate in an amount of 0.2-5% by dry substance (patent RF №2147408, class. And 23 K 1/00, 20.04.2000,).

However, the known method of obtaining a feed additive to reduce the moisture content of the raw materials used, the extraction of the juice, which requires additional expensive equipment and increases the cost of production of the additive. In addition, for the implementation of this method must have the seeds of soybean, sunflower meal and meal, and in addition, the proposed processing of raw materials does not reduce the level of fiber in feed additive.

Known methods do not allow to obtain high-quality vitamin feed Supplement high in protein and carotene and low in fiber.

Technical solution to the problem is to improve the quality of vitamin feed additive of green plants by increasing the content of carotene and protein and lower in fiber.

As the closest way to the same destination to the claimed invention by a combination of traits not found, the wording of the claims is made without dividing it into restrictive and distinctive parts.

Put the does can be accomplished by in the method of obtaining vitamin feed additive of green plants, including high-temperature drying grass cutting carried out to a moisture content of 40-45%, the separation sheet and stableboy faction, spend processing stem fractions, namely contamination by fungus Trichoderma, conduct cultivation for 20-24 hours at uniform mixing, then mix with leaf fraction, followed by drying to a moisture content of 10-12%.

The claimed method of obtaining vitamin feed additives from green plants different parameters humidity grass cutting before separation or other treatment option stem fraction, enter mycological object and lack of extraneous sources of protein (beans, meal and other).

These differences allow to draw a conclusion on the conformity of the proposed technical solution the criterion of "novelty".

The features distinguishing the claimed technical solution from analogues, aimed at achieving the task and not revealed by the study of patent and scientific literature in this and related areas of science and technology and, therefore, meet the criterion of "inventive step".

The method of obtaining vitamin feed additives from green plants is as follows.

Green mass of chopped alfalfa served in the drum sushi is lku and dried to 42%. Drying of green mass is conducted at standard temperature drying agent, and the temperature at the outlet of the drum is maintained within the range of 110-130°C. the Number of revolutions of the drum is standard to obtain herbal flour from green mass of alfalfa. Dried green mass of alfalfa together with a drying agent serves in a cyclone, then pneumoseparation to separate leaf and stem fractions. When drying the total mass of up to 42% sheet faction has a moisture content of 18-20%, and stem 48-52%, due to the large difference in mass fractions effectively separated. Received stableboy a lot with humidity 48-52% collected in the mixer and containerwith liquid culture of cellulolytic fungus Trichoderma (Trichoderma viride), at a concentration of 5-7% by weight fraction. Cultivation of the fungus spend 20-24 hours with periodic mixing. After this time are processed the mass of the belt conveyor is fed into the mixer where it is mixed with leaf fraction of the conveyor dryer and fed to the granulation line with dosukoi to a moisture content of 10-12%. To ensure continuity of the process of obtaining vitamin supplements from green mass at the specified method sheet fraction is mixed with stem, separated the day before. Data on the chemical composition of grass flour produced under the conventional and the proposed method, the pre is presented in the table.

IndicatorsHerbal flour obtained
the traditional waythe proposed method
Crude protein, %14,315,7
Crude fiber, %27,122,4
Carotene, mg/kg127213

As can be seen from the data presented in the table, the quality of herbal flour obtained by the proposed method is higher than in the traditional way, which is associated with a higher level in her crude protein and carotene and reduced level of fiber in it.

To obtain vitamin feed additives from green plants, grass cutting green mass hold up to humidity of 40-45%. If the moisture content of green mass is less than 40%, such moisture will not be enough for effective cultivation of cellulolytic fungus Trichoderma viride, and therefore, the destruction of the tissue would not be sufficient to obtain high-quality supplements because of the high fiber content. If the moisture content of green mass will be more than 45%, the humidity will not provide quality razdelenieza on pnevmoapparatury and as an additive will be low. The optimum moisture content of green mass before separation humidity is 43%. Stableboy fraction containerwith fungus Trichoderma (Trichoderma viride) and grown for 20-24 hours at uniform mixing. If the cultivation of the fungus will be less than 20 hours, the additive will be low due to the high content of fiber, which is not subjected to degradation by the fungus. If the time of cultivation will be more than 24 hours, it increases the duration of the technological process, but also reduces the quality of the supplements, as processed green mass becomes plastilinovye, which makes it difficult to enter and uniform distribution of the additive. Thus, the optimal time of cultivation cellulolytic fungus Trichoderma viride is 22 hours. Final drying vitamin supplements conduct to a moisture content of 10-12%. If the humidity vitamin supplements will make up less than 10%, even if such moisture additive will be poor, because when it is received there was a partial destruction of vitamins and protein. If the humidity vitamin supplements will be more than 12%, the humidity does not provide quality storage that will lead to its contamination toxinogenesis mushrooms. Optimal humidity vitamin supplements is the humidity of 11%.

The proposed method of obtaining vitamin cor the new supplements from green plants can reduce the content of cellulose, to reduce losses of carotene and protein and thereby improve the quality of supplements.

The method of obtaining vitamin feed additives from green plants, characterized in that it includes high temperature dried grass cutting carried out to a moisture content of 40-45%, the separation sheet and stableboy faction, spend processing stem fractions, namely contamination by fungus Trichoderma, conduct cultivation for 20-24 h with uniform mixing, then mix with leaf fraction, followed by drying to a moisture content of 10-12%.
