Abstract

This invention relates to fodder production, in particular, to methods for preparing feed from grain for feeding to agricultural animals. The aim of the invention is to increase the nutritional value of the grain and reduce processing costs. The fodder grain is treated with a chemical preservative, for example propionic acid, and just before feeding, the preserved grain is subjected to infrared irradiation with a wavelength of 4-6 µm with a specific radiation power of 25--29 kW / m and an exposure of 30-45 s. As a result of this treatment, the nutritional value of the grain is increased, the amount of dextrins increases to 23% o. When feeding the gobies with the feed obtained by the proposed method, the weight of the gobies increases by 4.0-10.3%, the feed consumption is 3-6.0% compared with known processing methods. 2 tab. g (L

WITH

The invention relates to fodder production, in particular, to methods for preparing feed from grain for feeding agricultural animals.

The aim of the invention is to increase the nutritional value of the grain and reduce processing costs.

Example. The feed grain (with a moisture content of 18–25% after pre-cleaning is treated with chemical preservatives, such as propionic acid, with a specific supply of preservative 0.75–1.00% into a centrifugal-type mixer. This treatment ensures the necessary storage conditions and to preserve the natural moisture of the grain. Before using the feed, the preserved grain is processed in a plant that includes a conveyor belt, infrared radiation sources with reflectors placed on top, and bunkers for loading and unloading grain. Infrared rays with a wavelength of 4 microns lead to grain ejection with a specific power of radiation flux of 26 kW / m and an exposure of 35 s. Infra} red rays cause intense internal heating of the grain, an increase in water pressure and 1 gx vapors in it, starch, contained in grain, swells and changes its structure, the transition to a stage close to turning it into sugar, as a result, the nutritional value of the feed grain will be increased.

The duration of the treatment and the power of infrared radiation for the grain of the main grain crops are given in tab. one .

on the more efficient for freshly harvested wet grains is the treatment with chemical cobalt, followed by treatment with intense infrared radiation, the nutritional value of the feed grain increases, the amount of descriptrin in the grain during such processing increases by 25%. The proposed method provides an increase in bull weight by 4-10.3%. The feed consumption is reduced by 3-6%, while reducing processing costs by eliminating the drying process for freshly harvested grain for storage and
