Description

The invention relates to agriculture, in particular to fodder production, and is intended for use in livestock farms, on farms and in feed mill enterprises.

The aim of the invention is to improve the quality of the feed by reducing the content of difficult-to-digest high molecular weight components in the feed and increasing the digestibility of the feed.

Example 1 (by a known method), To 1000 ml of a 25% suspension of compound SK-21 in tap water (60 ° C) with vigorous stirring was added 1.25 g of the enzyme preparation amylosubtilin (ratio enzyme preparation: compound feed 0.5: 100, M: M) incubated for 45 min with stirring and temperature

60 ° C determine the degree of destruction of the polysaccharide feed by the formation of reducing sugars (BC) in a solution by a known method and the degree of destruction of the feed proteins by the formation of primary amino groups (PA) in solution. Output VS6%, PA2% o.s. feed masses. Such a degree of destruction is low and only slightly exceeds the level of destruction of polysaccharides and feed proteins in the processing of feed without the use of an enzyme preparation.

PRI me R 2 (the proposed method). It is carried out according to Example 1, only different amounts of amylosubtilin are introduced, and different amounts of PEG and DAK are simultaneously added at different temperatures and incubation times.

The results of the degree of degradation of polysaccharides and proteins by the formation of BC and PA, depending on the ratio of components and mixing parameters, are presented in the table. From the data in the table (Experimental Examples 3-6), it follows that the optimal ratio of the components amylosubtilin: PEG: DAK: feed is (in M: M: M: M) 0.01-0.5: 0.025-0.25; 0.05: 99.965-9.2. Moreover, with increasing dosage of the enzyme preparation (in the optimal range, it is necessary to proportionally increase the content) PEG and DAK. A decrease in the amylosubtilin content below the limit (in relation to the weight of the compound feed) of 0.01: 100 leads to a decrease in the yield of BC and PA of less than 6.0 and 2.0%, respectively (Experiments 1 and 2). An increase in the ratio of amylosubtilin to the compound feed more than 0.5: 100) is inexpedient, since the output of aircraft and vehicles does not increase and remains at a constant level: 15.1-15.3 and 4.3-4.6%, respectively (experiments 7 and 8). Increasing the treatment temperature at an optimal ratio of amylosubtilin: PEG: DAK: compound feed in the range of 55-80 ° C allows reducing the processing time from 45 to 15 minutes (experiments 9-11.15); reducing the time (less than 15 minutes) is impractical from - due to a decrease in the BC and PA output (experiment 12), an increase in the processing time (more than 45 min) is also undesirable, i.e. does not lead to further growth of BC and PA (experiment 13), an increase in temperature (over 70 ° C) leads to a decrease in the activity of enzymes and a decrease in the yield of BC and PA (experiment 14), a decrease in temperature (less than 55 ° C) to reduce the output of the sun and the PA (experiment 16).

Example 3. It is carried out according to example 2 (in the conditions of experiment 5) only instead of compound feed SC-21 use compound feed SK-26 or SC-31. The BC yield in this case is 13.5 and 11.6% by weight of a.s. feed, and the output of the PA - respectively 4.0 and 3.9%.

Example 4. Performed as in Example 2 (in Experiment 5), only instead of the enzyme preparation amylosubtilin, which has amylase and protease activity, use maltavamorin (amylase) or pectofoetidine (pectinase, cellulase, hemicellulase, protease), or celloviridine (cellulase, hemicellulase), Dosage of enzyme preparations, PEG, DAK and SK-21 compound feed is the same as in Experiment 5. The output of the aircraft in the case of maltavamorin, pectofetidine and celloviridine is 14.5, 15.2, 15.3, 8.3% by weight as feed, the output of the PA - respectively 4.5, 2.1, 2.0%.

Example 5. Performed by example.

4, polypropylene glycol is used only to stabilize amylosubtilin or maltavamorin. When mixing the enzyme preparation, polypropylene glycol, DAK and compound feed in the ratio

0.4: 0.2: 0.04: 99.36 for 45 minutes at 55 ° C; the output of the aircraft in the case of amylosubtilin is 17.8%, and in the case of maltavamorin, 14.0% of a.c, the compound feed mass (SC 21) and the output of the PA is 4.5 and 4.4%.

PRI me R 6. It is carried out according to Example 4, only to stabilize pectofoetidine or celloviridine, sodium carboxymethylcellulose is used instead of DAK. When mixing the enzyme

of the preparation, PEG, carboxymethylcellulose, mixed feed in a ratio of 0.5: 0.25: 0.05: 100 for 45 minutes at 60 ° C, the output of the sun in the case of pectofoetidine and celloviridine is 15.0 and 8.4%, respectively

from as the mass of feed (CK-21), and the yield of PA is 2.0%.

Thus, the proposed method of feed preparation allows to significantly reduce the content of high molecular weight components in the feed (proteins, starch, cellulose, hemicellulose, pectin), significantly increase the digestibility of feed, the effectiveness of the use of enzyme preparations due to

high polymer feeds in soluble sugars and peptides. The yield of sugars and peptides in the application of the proposed method is increased by 2-3 times compared with the known. This is extremely important when using livestock feed, animal feed, as it will significantly reduce feed consumption per unit of animal production, reduce its cost, improve efficiency

use of enzyme preparations in fodder production and animal husbandry.
