Description

The invention relates to the field of veterinary medicine, biotechnology, in particular to the development of biologically active additives for birds.

Bile is a secret produced by hepatocytes. It has a complex chemical composition, which is based on bile acids, pigments, decay products of hemoglobin, mucin, cholesterol, lecithin, fats, some enzymes, hormones and other components. Such a complex composition of bile ensures the neutralization of the contents coming from the stomach into the small intestine, and also participates in the emulsification of lipids, the breakdown of lipids and proteins, the absorption of the split components, promotes normal intestinal motility, and has a bacteriostatic effect on the conditionally pathogenic and pathogenic intestinal microflora.

Bile acids (cholic, deoxycholic, metacholic, glycocholic, taurocholic) lower the surface tension of fat and other lipid drops, emulsifying them. This makes the substrate accessible to hydrolytic enzymes. Bile acids are involved in the transport of water-insoluble components (for example, stearins) through cell membranes into the blood and lymph channels. They stimulate the excretion of pancreatic juice and activate the activity of many enzymes of lipid, carbohydrate and protein metabolism.

The above indicates the feasibility of using natural bile of hens as a feed biologically active additive (hereinafter BAA), which provides an increase in live weight of chickens.

In domestic and foreign literature available to us, we have not found publications on the development of dry dietary supplements for poultry on natural chicken bile.

The aim of the invention is the development of dry biologically active additives for poultry based on natural chicken bile.

The technical result of this invention is the development of the composition and method of preparation of a dry preparation of natural chicken bile dietary supplement - "STIKFEL", providing when feeding broiler chickens, an increase in their live weight by 4.7% compared with the control over the entire growing period (during 49 days), with a decrease in feed intake by these chickens by 5.9%.

The specified result is achieved through the use of a filler in the process of preparing a dry preparation for dehydration of natural chicken bile, a bran dehydrator with a residual moisture content of not more than 2%, treated with hydrophobic aerosil grade AM-1-300, and using the components presented below in the following ratio (percent by weight):

natural chicken bile from 10.0 to 15.0 sucrose (stabilizer) from 5.0 to 6.0 aerosil hydrophobic AM-1-300 brands (disaggregant) from 1.5 to 2.0 residual moisture bran no more than 2% (filler-dehydrator) from 77.0 to 83.5

The essence of the invention lies in the fact that natural chicken bile is dried in a contact way using bran with a residual moisture content of not more than 2% as a filler-dehydrator, and sucrose is used as a stabilizer of the drying medium, while the ratio of the drying medium and the filler-dehydrator is from 1 : 3.6 to 1: 5.6.

Execution example

A method of preparing a dry preparation of dietary supplement "STIKFEL" includes the following stages:

- preparation of a drying medium;

- preparation of a mixture of dried bran with hydrophobic aerosil;

- dehydration of the drying medium with a mixture of dried bran with hydrophobic aerosil.

To obtain a dry preparation of bile, benign bran with a residual moisture content of not more than 2% is used. Bran drying is carried out in drying and drying ovens or other drying units at a temperature of from 90 to 104 ° C for at least 4 hours. Dried bran is stored at a temperature of from 4 to 30 ° C.

Bile is taken in accessible ways from the gall bladders of a dead bird and placed in a clean container. The drying medium is prepared as follows: 1.0 kg of bile is placed in a mixing container and 0.6 kg of stabilizer (sucrose) is added gradually with stirring. The mixing process is continued until the stabilizer is completely dissolved. The drying medium is stored in a closed container at a temperature of (6 ± 2) ° C for no more than 12 hours.

Dehydration of the drying medium is carried out in mixer grinders.

For one cycle of operation of the apparatus of the mixer-grinder, 8.2 kg of dry bran and 1.6 kg of drying medium are required. 8.2 kg of bran with a residual moisture content of not more than 2% and 0.2 kg of hydrophobic aerosil is introduced into a non-working apparatus (mixer-grinder), and the apparatus is turned on. The mixing time of the components is 2 minutes When the apparatus is in operation, the drying medium is gradually added to the resulting mixture in an amount of 1.6 kg. Mixing time is 10 minutes. Dewatering of dehydrated biomass is carried out in a vacuum drying oven at room temperature with a residual pressure of 50 to 60 mm Hg. within (2.5 ± 0.5) hours.

The finished product is unloaded in a special container and stored in a dark place at a temperature of (4 ± 2) ° C for 6 months, at a temperature of (15 ± 2) ° C for 1 month.

Ready dry preparation of chicken bile dietary supplement - "STIKFEL" is a loose powder of light gray color. The residual moisture content of the dry preparation of chicken bile is from 6 to 14%.

The work on assessing the effect of broiler chickens introduced into bile feed on their weight gain was carried out on the Competitor-2 cross-country up to 49 days old in the central vivarium of the GUSP EPH VNITIP in Sergiev Posad. Chickens were kept in R-15 cell batteries of 40 animals under the same microclimate conditions and planting density.

For the experiment, two groups were formed. Feeding and drinking chickens was plenty, with free access to feed and water. The experimental design is presented in table 1.

Table 1 - Scheme of experience Group No. The method of drug administration Number of goals 1 (dry bile preparation) 0.1% of the diet 120 2 (control) Without the inclusion of bile in the diet 120

During the experiment, the following indicators were taken into account: live weight of chickens by weekly, individual weighing throughout the entire breeding at 1-, 2-, 3-, 4-, 5-, 6-, 7-week olds; the growth rate of live weight of chickens according to the results of weighing at 1-, 2-, 3-, 4-, 5, - 6-, 7-week-old age.

The speed was determined by the absolute increase in live weight of chickens, calculated by the formula:

where U ₁ is the mass at the beginning of the growing period, g;

U ₂ - weight at the end of cultivation, g

The average daily weight gain of chickens was calculated by the formula:

where U / t is the average daily absolute increase, g · day ^-1 ;

t ₁ - age at the beginning of the growing period, days;

t ₂ - age at the end of the growing period, days;

The safety of the livestock was carried out daily, taking into account the cause of death. Feed costs for growing periods by accounting for a given feed and its residues for the corresponding period.

The results of weekly measurements of live weight of chickens are presented in table 2. Analysis of the results presented in table 2 indicates that the best result was obtained in group 1, where a dry bile preparation was used to feed broiler chickens throughout the entire growing period. Starting from the first week, the live weight of broiler chickens was 7.6% higher compared to the control. By the end of the rearing (49 days), the average live weight of the group 1 chickens exceeded the control by 4.74%. The difference in live weight of broiler chickens at 7 weeks of age between the experimental group and the control was achieved at P <0.05. The safety of the bird was almost the same and did not depend on the introduction of bile into the diet. In the experiment, a regular increase in live weight of broiler chickens was established weekly.

For 49 days of cultivation, the average daily weight gain of broiler chickens in the 1st group was 41.00 g, which is 4.86% higher compared to the control. The results of the calculations are presented in table 3

As can be seen from table 4, the lowest feed costs were at 6 weeks in the experimental group and amounted to 1.99 kg per 1 kg of growth, while in the control this indicator was 2.11 kg. It should be noted that this trend continued at 7 weeks, but the feed costs were higher.

Thus, studies have shown that the inclusion of dry chicken bile preparation additives in the amount of 0.1% of the diet of broiler chickens in the feed ration helps to increase their live weight, average daily gain and reduce the cost of feed consumption.

With the introduction of dry bile into broiler chickens, their live weight in 49 days increased by 4.74% compared with the control. The average daily increase on average increased by 4.86%, and feed costs decreased by 5.96% compared with the control.
