Abstract

FIELD: biotechnology; fodder production.

SUBSTANCE: disclosed is a method for producing a fodder additive, comprising enriching grain raw materials by saturating it with nutrients in a liquid-like medium, followed by disintegration in a grinding device, characterized by that enrichment of grain raw material is carried out in a blood medium at a ratio of grain raw material : blood of slaughter animals or poultry as 1:1 (wt.%) with exposure of 60 min, to produce a dough-like mass by disintegration in a grinding device, moulding into granules and subsequent dehydration by drying to 90-92% of dry substances content.

EFFECT: invention ensures enhancement of biological value of the target product due to enrichment of grains with heme iron and other macro- and micronutrients of natural nature.

Description

The invention relates to feed production and, in particular, to methods for preparing feed products based on grain raw materials.

A method for preparing feed products using up to 5.0% blood meal in their composition is known / Handbook. Compound feed, feed additives and whole milk replacers for animals. Composition and application / ed. by Doctor of Agricultural Sciences V.A. Krokhina. Moscow: Agropromizdat, 1990. – 304 p. Pp. 279-289. Appendix 3. Analogue/.

The disadvantages of this method are the relatively high labor and financial costs, due to the need for preliminary drying of blood in order to obtain flour, followed by its dosing and mixing with crushed grain raw materials.

A method for obtaining a product is known, which includes enrichment of grain raw materials by saturating them with nutrients in a liquid medium, followed by disintegration in a grate-knife type grinding device / Russian Federation Patent No. 2770859. Method for obtaining a pasty product. Prototype/.

The disadvantages of this method are the need to dose nutrients, mainly of a synthetic nature, which is associated with additional labor and financial costs, as well as the impossibility of including mineral substances in the nutrient water environment due to their insolubility, for example, iron.

The objective of the present invention is to reduce the energy, labor and resource costs associated with ensuring the accuracy of dosing and dissolution of macro- and micronutrients, as well as increasing the biological value and expanding the technological capabilities of the method. This is achieved by enriching the grain raw material in a blood medium, with a ratio of grain raw material: blood of slaughtered animals or poultry = 1: 1, (weight %) with an exposure of 60 minutes, with the production of a dough-like mass by disintegration in a grinding device, which is formed into granules, with subsequent dehydration by drying to 90-92% of the dry matter content.

The technical result consists in the fact that enrichment of grain raw materials in the blood medium allows to increase the biological value of the finished product due to the presence of heme iron in it, as well as other macro- and micronutrients of natural origin, while simultaneously reducing labor costs for their microdosing. At the same time, the possibility of introducing other fat-soluble vitamins into the blood medium allows to expand the technological capabilities of the method.

Fig. 1 shows the flow chart for implementing the proposed method,

Fig. 2 – hardware diagram for obtaining feed additive.

The method is carried out as follows.

The blood of slaughtered animals or poultry is mixed with grain raw materials in a ratio of 1:1 (weight %) and kept for an hour (Fig. 1). During this time, biologically valuable nutrients, together with plasma and water molecules, will pass into the grain structure due to the diffusion process, ensuring its swelling and softening of the internal grain structure.

In this case, larger particles found in the blood will cover the surface of the grains with a so-called film.

Subsequent grinding of the grain in this state will ensure the production of a dough-like mass that is easily formed and granulated. The resulting granules are dried to 90-92% dry matter content.

Example (Fig. 2). In the blood, for example, of slaughtered poultry, located in the dosing hopper 1, I place grain, for example, corn and feed wheat, in a ratio between them equal to 1:1, making a composition - blood: corn: wheat as 1: 0.5: 0.5 (weight %), that is, 100 liters of blood, 50 kg of corn and 50 kg of wheat are taken and mixed.

Next, the mixture is kept in bunker 1 for 60 minutes. During this time, moisture and nutrients penetrate the grain structure and swell.

Then, the resulting composition is ground using a grate-knife apparatus, for example, a mincer-grinder 2, and a dough-like mass is obtained, which is formed into granules and distributed in tray 3.

Wet granules are dried, for example, using the ESPIS-4-Universal 4 cabinet to a dry matter content of 90-92%, which ensures their high preservation.

The finished product is packaged and sold to the consumer.

Thus, the proposed method allows for a reduction in energy costs by at least 5.7 times compared to the preparation of blood meal and crushing of dry grain, while simultaneously enriching the finished product with heme iron and other natural macro- and micronutrients.
