Description

The invention relates to the field of agriculture, specifically to methods for the preparation of feed for farm animals.

Straw and herbs for cutting are widely used for livestock feed.

A significant disadvantage in the use of cutting is poor storage — it is hygroscopic, molds quickly and deteriorates.

Straw in shredded form is suitable for mechanized distribution to animals, but when fed, like grass cutting, animals experience damage to the gastrointestinal tract by sharp ends of shredded stalks. Therefore, before feeding the straw, it is usually steamed and mixed, which is very laborious.

Closest to the invention is a method for preparing full-sized briquettes using grass cutting, straw and concentrates.

This feed is difficult to digest.

The aim of the invention is to eliminate the noted disadvantages, to improve the quality of the prepared feed and its safety.

The goal is achieved as follows.

Using an existing herbal dryer, for example, ABM-0.65, they prepare herbal cutting with a moisture content of 30-35% (the productivity of the core increases 1.5 to 2 times), which is fed to a special machine of a rolling type, for example grinder weight of the construction of the Moscow Agricultural Academy. K.A. Timir of the pharynx and the Scientific Research Institute of Agriculture of the central regions of the non-Chernozem zone. The same chopper-blender is fed from straw mowers р straw and herbs are ground in the grinder, this straw splits along the fibers. In the formed straw fibers, due to the percussive actions and friction, the grass cutting pieces of the grass, formed from the 5 minimizer and mixer in the process of its operation, form a homogeneous feed mixture. Vegetable juice extracted from cutting during grinding and destruction provides the necessary

0 connection of briquette particles. The feed mixture obtained in the mixer is sent to a press briquette maker, for example, a VIMa construction, which forms briquettes from it without the use of bonding components. According to the invention, in particular, shredded straw with a particle size of 7-10 cm, enriched to 30% of sex, is subjected to splitting in the special apparatus with an average particle length of 2.8 cm and destruction of interstices, acquiring a fibrous state with simultaneous rubbing of particles grass cutting. A weight equivalent to good hay is obtained, which can be briquetted with the inclusion of necessary additives or used in loose form. Cutting herbs as a component used in the preparation of the feed mixture come directly from the drying units, have an increased moisture content (8-10% higher than the usual cutting), which allows increasing the productivity of drying units by 15-17%. It also has a higher the content of carotene, amino acids, water- and salt-soluble protein fractions, and when rubbed in the apparatus, juice is extracted, which enriches the straw and creates the necessary connection between the particles during briquetting the mass without adding water. Preparation of the feed mixture is performed in a grater-type apparatus, the work process of which is based on the material splitting between the moving wedge and the stationary grating, surface, provided that the angle of attack of the working face of the wedge is equal to or less than the sum of the friction angles of the contacting materials. at a speed of at least 15 m / s. According to research data, the degree of compression of the mass at the time of exposure of the working body is 3.5–5. The effectiveness of rubbing particles in the straw is 0.97. Cutting particles that are rubbed into straw fibers improve the feed quality of straw, and cutting in this form is not selected by animals when feeding the mixture. Prepared in this way, the mixture has high feed qualities. So, according to the analytical laboratory of the Research Institute of Agriculture of the central regions of the non-black-earth zone, there was protein 13, nitrogen 2.08, carotene 6.24 and cellulose 33.4% in the cereal-straw cutting (without feed) with equal content of these components. . The feed mixture contributes to the preservation of grass cutting, since the chopped straw absorbs its juice and the product does not spoil, even if it is in the placer. The mixture can also be pressed. The experiment with feeding the body with the feed mixture prepared by the above method was successful. The mixture, having qualities that are almost equivalent to hay, is eagerly eaten by animals. By the described method, the feed mixture can be made in any household, starting from the moment of preparing grass cutting (June) and before the onset of frosts (October). This method makes it possible to provide modern livestock complexes with high-grade roughage. The invention The method of preparation of the feed, including mixing chopped straw and grass cutting, is also so that, in order to improve the absorbability of the straw and increase the palatability of the feed, chopped straw is ground with grass cutting during mixing. .
