Description

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

The aim of the invention is to improve the quality of the feed by reducing the concentration of high molecular weight components and increasing its digestibility.

Example 1 (by a known method). To 100 ml of a 25% suspension of the SK-21 compound feed in tap water (60 ° C) with vigorous stirring (a mixer with twin blades, 450 rpm) was added 1.0 g of the enzyme preparation amylosubtilin and 1.0 g of amylorizine (ratio enzyme preparation : feed

0.8: 100, M: M), incubated for 45 min with stirring and a temperature of 60 ° C. The degree of destruction of feed polysaccharides is determined by the formation of reducing sugars (BC) in a solution according to a known method and the degree of destruction of feed proteins by the formation of primary amino groups (PAs) in a solution by the Fields method. In this case, the output of the sun is 10%, PA 3% o.s. feed masses.

PRI me R 2 (the proposed method). It is carried out according to Example 1, only different amounts of amylosubtilin, maltavamorin, pectofeethidine are introduced. celloviridin at their total (constant) mass of 0.8 g, as well as 0.01 g of polyethylene glycol (PEG) and 0.01 g of dialdehyde starch

(DAK) at 55 ° C. Incubation time 45 minutes, the ratio of the combined enzyme preparation, PEG, DAK, feed (by weight) is 0.32: 0.004: 0.004: 99.672

The output of BC and PA depending on the ratio of various enzymes is presented in Table 1.

From the data of Table 1 it follows that the optimal ratio of enzyme preparations is in the range (by weight) from 1: 0.5: 0.4: 0.1 to 1: 1: 0.8: 0.2 (experiments 9-12 ).

Example 3. Performed as in Example 2 under the conditions of experiment 11. The difference is that different amounts of PEG and DAC are introduced, and also the total amount of the combined enzyme preparation is changed (keeping the relative content of amylosubtilin, maltavamorin in it , pectofoetidine and celloviridine according to experiment 11), change the temperature and processing time of compound feed composition of enzyme preparations.

The results of controlling the degree of degradation of polysaccharides and proteins by the yield of B C and PA, depending on all these parameters, are presented in Table 2.

From the data of table 2 (experiments 3-6) it follows that the optimal ratio (by weight) of the enzyme preparation, PEG DAK: mixed feed 0.01-0.5: 0.001-0.05: 0.001-0.05: 99.9988-99 , 39 A decrease in the content of the combined enzyme preparation below the limit (in relation to the weight of the compound feed) than 0.01: 100 does not lead to a decrease in the yield of the AF and PA less than 5.5 and 1.9%, respectively (Experiments 1 and 2, Table 2). An increase in the ratio of the combined enzyme preparation to the mixed feed (more than 0.5: 100) is impractical, since the output of the aircraft and the aircraft does not increase and remains at a constant level - 20.4–20.5 and 6.8–6.9% respectively (experiments 7 and 8, table 2). An increase in the treatment temperature at the optimum mass ratio combined enzyme preparation: PEPDAK: mixed feed in the range of 55-70 ° C allows reducing the processing time from 45 to 15 min (experiments 9-11, 15, Table 2), reducing the time (less than 15 min ) it is impractical because of a decrease in the yield of the BC and PA (experiment 12, table 2), an increase in the processing time (more than 45 minutes) is also impractical, since it does not lead to a further increase in the output of the BC and PA (experiment 13, table 2), an increase in temperature (over 70 ° C) leads to the inactivation of enzymes and a decrease in y output of VS and PA (experiment 14. table 2), and a decrease in temperature (less than 55 ° C) is impractical because it does not lead to an increase in the yield of VS and PA (experiment 16, table 2).

Example 4. Performed in Example 3 in Experiment 5 (Table 2), but

instead of compound feed SK-21, compound feed SK-26 or SK-31 is used, in this case, the output of the aircraft was 17.5 and 15.2% of a.s. mass of animal feed, and the output of the PA 6.0 and 5.9%.

Example 5. Performed by example.

3 in Experiment 5 (Table 2), but polypropylene glycol is used instead of PEG. The ratio (by weight) of the combined enzyme preparation, polypropylene glycol, DAC and feed

is 0.4: 0.04: 0.04: 99.52. In this case, it is established that the output of an aircraft under such conditions is 19.1% of a.s. the mass of feed (CK-21), and the output of the PA 6.1%.

Example 6. It is carried out according to Example 3 under the conditions of experiment 5 (Table 2), but only sodium salt of carboxymethylcellulose is used instead of DAK. The ratio by weight of the combined enzyme preparation, PEG.

carboxymethylcellulose, feed feeds 0.4: 0.04: 0.04: 99.52. In this example, the BC output was equal to 19.4% of a.s. the mass of feed (SC-21), and the output of the PA 6.2%.

Thus, the proposed method

allows to increase the efficiency of the processes of depolymerization of high-molecular compounds of feed (protein, starch, cellulose, hemicellulose, pectin) and, consequently, increase the efficiency

use of enzyme preparations, as well as feed digestibility.
