Description

The invention relates to agriculture and can be used in poultry farming.

The aim of the invention is to increase the yield of young.

Example 1. A multienzyme composition (MEK) consisting of a complex of enzyme preparations of lysozyme GH and protosubtilin GH with lysozyme activity of 150 units / g and proteolytic activity of 3.5 units / g is introduced into the basic diet at a dose of 0.05; 0.1; 0.3; 0.5; 0.6% of the total mass, feeding are from daily to 7 weeks of age.

The created IEC has an indirect effect on the egg of the chickens during their formation, promotes the accumulation of an increased amount of proteins in the egg protein, increases the level of carotenoids.

and vitamins A and B2 in chicken yolk and thereby increases the hatching of chickens.

The feasibility of using IEC, which improves the quality of breeding chickens, is shown in biochemical studies of chicken eggs.

Table 1 shows the data of studies of eggs.

From table 1 it can be seen that supplements of MEK in small and large quantities did not give positive results. Biologically complete chicken eggs were obtained by adding IEC in an amount of from 0.1 to 0.5% by weight of the feed.

The highest quality of eggs was obtained when feeding the compound feed to the hens with the addition of 0.3% MEK. Thus, in these vitamin Ba eggs there was 5.23 µg / g versus 4.09 µg / r in the control, vitamin A 7.78 µg / g versus 7.58 µg / g, carotenoids 35.40 µg / g

against 30.80. In addition, an increase in the protein content in the protein (10.26% versus 9.55%) was noted. Morphological indicators of incubatory eggs improved with the use of this dose (0.3%): the shell thickness increased to 34.74 MMK against the control 33.74 MMK, and the ratio of protein to. yolk 2.16 vs. control 2.08.

From the data of the experimental groups presented in Table 1, it can be seen that the use of IEC as a way to improve the quality of breeding chickens increased the content of vitamin B2 in the yolk by 0.25 μg, vitamin A by 0.18 μg, carotenoids by 5.72 μg, the amount Protein in protein increased from 9.6% to 10.26%, the shell thickness increased by 0.76 MMK.

Doses of 0.05% and 0.6% by weight of the feed did not give a positive result.

Example 2. The effectiveness of MEK as a way to improve the quality of pedigree pullets (1 g of which contains 150 units / r of lysozyme and 3.5 units / g of proteolytic activity) was tested on breeding hens from daily to 7 weeks of age.

Chickens at all age periods of cultivation were fed with complete feed and kept in the same conditions.

The control group received feed without IEC additives. The bird of the experimental groups with compound feed received MEK prepared from lysozyme GZx (lysozyme activity 150 units / rj and prdtosubtilin GZx (proteolytic activity 3.5 units / g). MEK was introduced into the compound feed for chickens in an amount of 0.05% by weight of feed , 0.1; 0.3; o; 5; 0.6%.

At the age of 18 weeks, even-aged cocks were set to these / chickens in a ratio of 10: 1, who received compound feed without IEC additives.

In order to ascertain the quality of the breeding chickens from chickens at 36-4 8 weeks of age, all the eggs laid were collected, sorted and taken for incubation. It was laid in the hatchery with 4 egg laying from each experimental and control groups of chickens.

Table 2 presents comparative data on the use of MEK in different doses and the known enzyme preparation of yeast gelitin GH and the control group.

From table 2 it can be seen that the doses of 0.5% and 0.6% did not give positive results compared with the control and in a known manner.

IEC action to improve quality

breeding hens, determined dose of 0.1-0.5%. However, the best results in the action of MEK were obtained from a dose of 0.3%. This amount of IEC was most effective in improving the quality of eggs compared to control. So, from the hens of hens that received this amount of IEC, more full-bodied, healthy chickens were received: the number of suffocates decreased.

1.7%, frozen - by 3.2%, blood ring - 0.7%, the number of eggs suitable for incubation also increased by 7.9%, fertility by 0.2%, hatchability of eggs by 6.9% and young hatching increased by 6.3% compared to control.

Comparing the experimental groups with the prototype (Table 2), it can be seen that the addition of IEC at a dose of 0.3% for all the above parameters gave the best results. Fertilization

increased by 0.1%, the number decreased: asphyxia by 1.0%, frozen by 1.2%, blood rings by 0.4%, the output of young animals increased by 3.9%, hatchability by 5.7% %, good for incubation eggs 5.6%.

The use of the proposed method increases the hatchability of eggs by 5.1–6.9%, increases the output of young animals by 3.6–6.3%, increases the number of fit

for incubation of breeding eggs by 4.2-7.9% more compared to the control group, the morphological and biochemical qualities of eggs laid are improved.
