Description

The invention relates to animal husbandry and feed production and is aimed at optimizing the feeding of monogastric animals.

Currently, in animal feed, molasses obtained from sugar wastes, fodder or sugar beets are used as a source of sugars. In places of industrial processing of wood, hydrolytic sugar is produced, which is also used in animal diets (see Bogdanov G.A. Feeding of farm animals. M: Agroproduct, 1990, p.184-198).

The above feed additives have significant disadvantages. Sugar wastes in the form of molasses have a high content of heavy metals, pesticides, nitrates. To grow sugar and fodder beets in connection with constantly increasing energy prices becomes unprofitable, the hydrolysis sugar produced from waste wood has a high content of furfural (see Ernst L.K., Naumenko Z.M., Rudenko N.P. Production and use of hydrolysis sugar in livestock production. M: Rosselkhozizdat, 1990, p.206).

For the prototype adopted a patent of the Russian Federation 2265364 for a method for producing feed molasses. In this method, the grain is crushed to particles with a size of 2-4 mm, then, gradually adding water, pass through a cavitator at a temperature of 35-40 ° C. The acidity of the mixture is maintained with hydrochloric acid and soda ash, after which the enzymes alphaamylase and xylase are added, then hydrochloric acid is added, the pH of the medium is adjusted to 5.5-6.0 and glucavamorin is added, the saccharification process is carried out for 4-6 hours.

This method has several significant disadvantages. To maintain the pH, chemical reagents, such as hydrochloric acid, soda ash, are used; protein breakdown to easily digestible amino acids is not provided. Due to the long process of starch hydrolysis, high energy costs are required, there is a need to purchase steam generators.

The technical task is the processing of wheat and rye grain into easily digestible animal products. This is achieved by the fact that the crushed raw material is loaded into a rotary pulsation dispersant, after which it is poured with electroactivated water with a given pH value of 4.5-5.0, the suspension formed is diluted with amylolytic enzymes, then proteolytic enzymes are added, and the hydrolyzate temperature is maintained at 60- 65 ° C.

As a result of the fermentation process and the effect of cavitation, complex carbohydrates are broken down to simple sugars, glucose and maltose, and proteins to a complex of amino acids, which, entering the animal’s body, are easily absorbed in the digestive tract without the additional cost of breaking them down.

The proposed method is implemented as follows. A solution of prepared electroactivated water with a pH of 4.5-5.0 in an amount of 40 liters is poured into a rotary pulsation dispersant in an amount of 40 liters, after which crushed grain is added in portions. The mixture is stirred for one hour, while the temperature of the hydrolyzate reaches 60-65 ° C. Then, it is diluted with amylolytic enzymes for one hour, after which proteolytic enzymes are added. Hydrolysis of complex carbohydrates and proteins to simple compounds occurs within 5-7 hours.

As a result of fermentation, starch is broken down into sugars, and protein into amino acids, and the chemical composition of the glucose-maltose-amino acid feed additive is shown in the following table.
