Description

FIELD OF THE INVENTION

The invention relates to industrial poultry farming and can be used for rehabilitation from infectious pathogens of hatching poultry eggs.

State of the art

A known method of processing eggs at high temperatures (AS USSR No. 1706494, A01K 43/00, 1989), a method of treating magnetized water with drugs (AS USSR No. 1780667, A 01K 41/00, 1990), a laser method processing of eggs (AS USSR No. 1780668, A01K 45/00, 1990), a method for pre-incubation disinfection of eggs and incubators with a surface-active drug ATM (patent No. 2099939, А01К 43/00, 1997) and others.

Also known is a method of disinfection of eggs before incubation, in which 1-3% solutions containing a composition of 4 substituted ammonium compounds with salts of phosphate and sodium carbonate are used as a disinfectant. Processing of eggs is carried out for 2-4 minutes by immersion in a solution of a composition heated to 40 ° C. After dipping, the eggs are removed, dried and laid for incubation (AS USSR No. 900830, A01K 43/00, 1982).

The most widely used method of processing hatching eggs with formaldehyde vapors (Prototype. Veterinary legislation v. 4, M., 1988, p. 411-415). The method involves a 6-fold processing of eggs before and during incubation.

The disadvantages of the known methods are the length of the disinfection process, the need to use heated solutions to a certain temperature, which is a health risk, the presence of additional containers for bathing eggs or egg trays, which create hygienic inconvenience in the hatchery.

Repeated and uncontrolled fumigation with formaldehyde leads to pathological changes in the internal organs of the embryo and an increase in mortality of the embryos in the second half of incubation. The use of formaldehyde vapor has an adverse effect on staff in whom it causes allergic reactions, increases the number of respiratory diseases and is a carcinogen for people, animals and birds.

Disclosure of invention

The objective of the invention is to develop a method of producing an environmentally safe and cheap antiseptic agent with a prolonged bactericidal effect, and the use of means for the rehabilitation of objects of livestock surveillance in a hatchery.

The technical result boils down to security and obtaining a cheaper tool.

The technical result is achieved using a method for treating poultry hatching eggs, including surface treatment with an aqueous solution of a milk whey-based preparation with lactulose and a quaternary ammonium compound of trimethyl octadecyl ammonium bromide, while an aqueous solution of a milk-based preparation with lactulose and a quaternary ammonium compound of trimethyl octadecyl ammonium bromide use a 0.1-0.2% aqueous solution of the drug, taken in equal proportions and diluted in water in the ratio nii 1:10, which is used for hatching eggs 2-4 hours before laying them for incubation.

The essence of the method of processing hatching birds is as follows.

Before processing the hatching eggs, the inner walls of the hatching cabinets are sanitized by a single spray of the Bactericide antiseptic (see Nikolayenko VP Antiseptic bactericide for poultry farming // Veterinary Medicine, 2004, No. 3, p. 34-46), then process trays, carts, and also the surface of the hatching eggs with a preparation containing 0.1-0.2% aqueous solution of the preparation, including whey, lactulose, quaternary ammonium compound trimethyl octadets taken in equal proportions and diluted in water in a ratio of 1:10 ammonium bromide sludge, water - the rest, after which a thin polymer protective film is formed on the disinfection objects, which protects the eggs from penetration of microbes during the entire incubation period, and also disinfects the surface of the egg shell from the causative agents of Escherichiosis, salmonellosis, mycoplasmosis, streptococcosis, pseudomoniasis and staphylococcosis for the entire incubation period.

The drug is a light yellow liquid containing a highly concentrated salt of tetra-substituted ammonium in bromoform-trimethyl octadecyl ammonium bromide and milk whey with lactulose, taken in equal proportions and diluted in water in a ratio of 1:10.

The drug is highly soluble in alcohol, hot water 50-60 ° C, does not have an irritating, skin-resorptive and allergic effect, is not toxic, without an acute odor, does not cause corrosion of metal equipment, has a prolonged bactericidal, virucidal and fungicidal effect for one month , in the conditions of the hatchery, which compares it favorably with other drugs that do not have a prolonged bactericidal action and are used in the form of water-alcohol solutions with the addition of toxic aldehydes, chlorine or Nola.

The drug has a pronounced bactericidal effect against gram-positive and gram-negative microorganisms. Its prolonged bactericidal, virucidal and fungicidal action was established during the entire incubation period due to the formation of a thin polymer film on the treated surface, which serves as a barrier to microflora and has a bactericidal effect throughout the entire period of incubation of eggs.

The implementation of the invention

An example implementation of the method of processing hatching poultry eggs.

To process hatching poultry eggs, three batches of 10 thousand eggs each were selected, which were placed in trays and carts.

The first batch of eggs, along with trays and trolleys, is treated with a once-wet method of a 0.1% aqueous solution of a preparation based on milk whey with lactulose and a quaternary ammonium compound trimethyl octadecyl ammonium bromide, taken in equal proportions and diluted in water in a ratio of 1:10, at at the same time, as a water solution of a preparation based on whey with lactulose and a quaternary ammonium compound trimethyl octadecyl ammonium bromide, a 0.1% aqueous solution of the drug is used, which is treated with inc bation eggs 2-4 hours before laying them for incubation.

The second batch of eggs is treated with a 0.2% solution of the preparation, including surface treatment with an aqueous solution of the preparation based on milk whey with lactulose and the quaternary ammonium compound trimethyl octadecyl ammonium bromide taken in equal proportions and diluted in water in a ratio of 1:10, while as an aqueous solution of a preparation based on whey with lactulose and a quaternary ammonium compound trimethyl octadecyl ammonium bromide, a 0.2% aqueous solution of the drug is used, which is treated with ubatsionnye eggs for 2-4 hours before setting them for incubation.

Irrigation of eggs is carried out using an imported sprayer. Two to three hours after treatment, hatching eggs placed in trays in trolleys are placed in incubators pretreated with 0.2% Bactericide.

A third batch of eggs (control) is treated six times with formaldehyde vapors: 1st - after 2 hours after laying, 2nd - after sorting the eggs in the warehouse, 3rd - after sorting in the hatchery, 4th - 6 hours after the start of incubation 5th - before transferring the embryos to the conclusion, 6th - in hatchers. Incubators and processing equipment are treated with formaldehyde vapor.

Bacteriological control of the shell washings of the incubated eggs is carried out before processing, then 7 and 18 days after the start of incubation on Escherichia coli, Staphylococcus aureus and Salmonella. The results of hatching eggs and bacteriological studies of swabs from the surface of the egg shell are presented in the table.

Table Study period A single treatment of hatching eggs with 0.1-0.2% solution of the drug (experience) Six-fold egg sanitation with formaldehyde vapor (control) 0.1% 0.2% Before processing Escherichia coli in 5 samples, salmonella in the 1st sample, staphylococci in 2 samples. E. coli in 4 samples, salmonella in the 1st sample, staphylococci in the 1st sample. E. coli in 6 samples, salmonella in 3 samples, staphylococci in the 1st sample After processing after 7 days No causative agent of bacterial infection No causative agent of bacterial infection Escherichia coli in 3 samples, salmonella in the 1st sample, staphylococci in the 1st sample After processing after 18 days - - Escherichia coli in 4 samples, salmonella in 2 samples, staphylococci in the 1st sample The output of young birds,% 93.9 93.8 89.2 The safety of young animals up to 20 days of cultivation,% 98.5 98.4 95.2

After a single sanitation of poultry incubation eggs with a 0.1-0.2% solution of the preparation, the surface of the egg shell was disinfected from bacterial pathogens, while in the control, 6-fold disinfection of eggs with formaldehyde vapors of bacterial infections was isolated throughout incubation.

The output of young birds in the experimental batch was 4.6–4.7% higher than in the control, and the safety of young animals up to 20 days of age was also higher by 3.2–3.3%. Economic efficiency per 1 million incubated eggs is more than 400 thousand rubles.
