Description

The invention relates to agriculture, in particular to methods for feeding broiler chickens.

A known method of feeding poultry, including lake silt (sapropel), which is added to the diet of broiler chickens in the amount of 10 and 15%, which contributes to an increase in live weight by 2.0-2.5% and increase safety by 2.0-2, 6% (see About the possibility of using sapropel in feeding meat chickens. Maltseva N.A., Yakunina I.I., Maltsev A.B. // Collection of scientific papers. Achievements and urgent problems of poultry farming in Siberia, 1997, v. 4 , p. 69-71).

However, the high moisture content of sapropel makes it difficult to transport and use as part of feed mixtures.

There is a known method of feeding, including granulated sapropel up to 1.5% in the composition of complete feeds (see Granulated sapropel - a source of biologically active substances. Egorov I., Chesnokova N., Prisyazhnaya L. // Advanced scientific and industrial experience in poultry farming: Express- Information. 1998, No. 1, pp. 16-17). However, when drying sapropel, some of the nutrients (organic) are lost, which reduces economic and livestock performance.

The objective of the invention is to improve the zootechnical and economic indicators of growing broiler chickens by using an extract of sapropel extracted from a lake in the Omsk region, which is added to the water at a dose of 1.0-1.5% of the amount of water consumed in the age of 1–42 days 2.0-2.5% in the age period of baking 1-10 days.

Sapropel extract is a non-specific stimulant of natural origin. It was obtained by extraction of sapropel extracted from a lake in the Omsk region. The preparation contains water and alcohol soluble mineral and organic substances:

- tar-like substances that stimulate the regeneration of the mucous membrane;

- ichthyol-like substances that have a stimulating effect on the whole organism of a bird and local bacteriological action;

- hormone-like substances and peptides that affect the internal secretion system (stimulation of hormone production), immunity, blood formation, general regenerative stimulation of organs and tissues of the body;

- enzymes;

- antioxidants involved in antimicrobial and antiperoxidation protection;

- energy substances.

Example 1

The experiment was carried out on broilers of Sibiryak cross-country from daily to 42 days of age. The groups were completed according to the periods of drinking 1-10, 11-22, 23-42 days, the control (sapropel extract was not added). For each age period, doses of sapropel extract from 0.5 to 3.5% were used (table 1). The calculation of zootechnical and economic indicators was carried out for the entire growing period (1-42 days).

Technological parameters (feeding front, watering, temperature and humidity, light) were the same for all groups. The control and experimental groups were fed with placer feeds, balanced in all nutrients according to the methodological recommendations for working with Sibiryak cross birds, and the feed was distributed manually. The nutritional value of the diet was calculated on a computer program taking into account the actual nutritional value of feed raw materials included in the feed mixture recipe. Sapropel extract was dissolved in water and evaporated. The administered dose of sapropel extract was calculated from the total water intake by the chicken per day (Table 2).

The results of the experiment are presented in tables 3, 4, 5, 6.

From table 3 it is seen that the broilers of the experimental groups showed a higher preservation of 97.2-99.6%, while in the control group - 96.3%, which is 1.0-3.0% lower.

In chickens of the experimental groups receiving sapropel extract in the age period of baking from 1-10 days, an increase in live weight was observed by 6.2-12.5% higher compared to the control group. The greatest increase in live weight was observed when using sapropel extract in a dose of 2-2.5%. The introduction of sapropel extract in a dose of 3.0-3.5% does not affect the increase in live weight of chickens.

From table 5 it is seen that in all experimental groups, the cost of feed is lower by an average of 7.8%.

It can be seen from the table that the greatest economic effect is observed when using sapropel extract in the first ten days, and in other periods of cultivation, there is a decrease in economic efficiency due to an increase in water consumption and, accordingly, sapropel extract. The greatest profit was obtained when using sapropel extract in a dose of 2.0-2.5% in the age period of baking 1-10 days, which is 67.8% higher compared to the control group, in the age period of baking 11-22 days profit by 36 6% higher.

The experiment was carried out on broilers of Sibiryak cross in the age period of 1-42 days, similar to that described in example No. 1, this group of chickens received sapropel extract in a dose of 1-1.5% of the amount of water consumed.

In chickens of the experimental groups receiving sapropel extract in the age period of baking from 1-10 days, an increase in live weight was observed by 6.2-12.5% higher compared to the control group. When introducing 1.0-1.5% of sapropel extract in the age period of baking 1-42 days, an increase in live weight up to 12% was observed, which is not lower than other experimental groups. The introduction of sapropel extract in a dose of 3.0-3.5% does not affect the increase in live weight of chickens.

From table 11 it is seen that in all experimental groups, feed costs are lower by an average of 7.8%, in the group that received 1.0-1.5% of sapropel extract in the age of 1–42 days of drinking, a decrease in feed costs of 1 kg gain in live weight was 10-12% compared with the control group.

The use of sapropel extract in the age period of baking 1-42 days of sapropel extract in a dose of 1.0-1.5% gives a profit higher by 17%.

Thus, the improvement of zootechnical and economic indicators of broiler chickens was experimentally proven when using sapropel extract in a dose of 1.0-1.5% in the age period of 1–42 days of baking or 2.0-2.5% in the age of 1– 10 days.
