Description

FIELD OF THE INVENTION

The invention relates to industrial poultry farming and can be used for reorganization from the pathogens of infectious diseases of objects of zootechnical surveillance of hatcheries and poultry hatching 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, A01K 41/00, 1990), a method of laser treatment eggs (AS USSR No. 1780668, A01K 45/00, 1990), a method for pre-incubation disinfection of eggs and incubators with an ATM surfactant (patent No. 2099939, A01K 43/00, 1997) and others.

There is also known a method of disinfection of eggs before incubation, in which 1-3% solutions containing a composition of a 4-substituted ammonium compound 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, t.4, M., 1988, s.411-415). The method involves a 6-fold processing of eggs before and during incubation.

The disadvantages of the known methods is 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 by the method of sanitation of objects of zootechnical control of the hatchery and hatching eggs, including surface treatment with an aqueous solution of the Trisan preparation based on a quaternary ammonium compound, while 0.05-0.2% is used as an aqueous solution of the drug based on a quaternary ammonium compound an aqueous solution of a composition of trimethyloctadecyl ammonium bromide - 40%, trimethyl octadecyl ammonium iodide - 40%, and trimethyl octadecyl ammonium acetate - 20%, which are treated with zoote hatchery-ethnic monitoring and hatching eggs for 2-4 hours prior to loading of eggs for incubation.

The invention consists in the following. Before processing the hatching eggs, the inner walls of the hatching cabinets are sanitized by spraying Trisan once, then the trays, carts, and the surface of the eggs are treated, after which a thin polymer protective film forms on the disinfection objects, which protects the eggs from the penetration of microbes throughout the entire period incubation, and also disinfects the surface of the shell of eggs, the walls of the incubator and other technological equipment from the causative agents of Escherichiosis, salmonellosis, mycoplasmosis, ptokokkoza, pseudomonosis, candidiasis and stafilokokkoz for the whole incubation period.

The Trisan preparation is a pasty white-yellowish substance containing a composition of three substances, the first of which is a highly concentrated tetra-substituted ammonium salt in bromoform, the second is a highly concentrated tetra-substituted ammonium salt in iodine form, and the third is a highly concentrated tetra-substituted ammonium salt in acetate form.

The method of obtaining the drug "Trisan" is as follows: take the salt of tetra-substituted ammonium trimethyl octadecyl ammonium bromide and trimethyl octadecyl ammonium iodide and trimethyl octadecyl ammonium acetate in a ratio of 4: 4: 2 and mix.

As a result of mixing the components, a pasty substance of a whitish-yellowish color is obtained - the Trisan preparation. The drug is highly soluble in alcohol, hot water 50-60 ° C, dimethylformamide, does not have an irritating, skin-resorptive and allergic effect, is not toxic, without an acute odor, does not cause corrosion of metal equipment, and has a prolonged bactericidal, virucidal and fungicidal effect during one month, in the conditions of the hatchery, which distinguishes it from other drugs that do not have a prolonged bactericidal effect and are used in the form of water-alcohol solutions with the addition of toxic alde guides, chlorine or phenol.

The drug "Trisan" 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 for one month.

The implementation of the invention

An example of the method of sanitation of objects of zootechnical control of the hatchery and hatching eggs. To reorganize the objects of zootechnical control of the hatchery, three batches of 120 thousand eggs each were selected, which were placed in trays and carts.

The first batch of eggs, along with trays and trolleys, was treated once with a wet method with a 0.05% aqueous solution of the Trisan preparation. The second batch of eggs was sanitized with a 0.2% Trisan solution. Irrigation of eggs and processing equipment was carried out using imported sprayers and a spray gun connected to a compressor. Two to three hours after treatment, hatching eggs placed in trays in trolleys were placed in incubators pretreated with a 0.1% solution of the drug.

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

Bacteriological control of egg shell swabs and the surface of technological equipment was carried out before disinfection, then after 7, 13 and 18 days after the start of incubation, 30 samples for Escherichia coli, 30 for Staphylococcus aureus, 30 for Salmonella, 30 for Candida, 30 on aspergillus.

The results of bacteriological and fungicidal studies of swabs from the surface of the eggshell and objects of zootechnical control of the hatchery are presented in the table.

Backdoor Period Single sanitation of eggs and hatchery equipment with 0.05% -0.2% Trisan solution (experience) Six-fold egg sanitation with formaldehyde vapor (control) 0.05% 0.2% Before disinfection of eggs and equipment E. coli in 2 samples, salmonella in 1 sample, staphylococcus in 2 samples. E. coli in 3 samples, salmonella in 1 sample, staphylococcus in 1 sample. E. coli in 4 samples, salmonella in 2 samples, staphylococci in 1 sample After processing after 7 days No causative agent of bacterial infection No causative agent of bacterial infection E. coli in 4 samples, salmonella in 2 samples, staphylococci in 1 sample After processing after 13 days No causative agent of bacterial infection No causative agent of bacterial infection E. coli in 6 samples, Salmonella in 2 samples, Staphylococcus in 2 samples After processing after 18 days --------- --------- E. coli in 7 samples, salmonella in 3 samples, staphylococci in 3 samples The output of young birds,% 94.8 95.1 91.2 The safety of young animals up to 20 days of cultivation,% 99,2 99.3 96.4

After a single sanitation of eggs and objects of veterinary supervision of the hatchery with a 0.05-0.1% Trisan solution, the surface of the shell of the eggs and equipment was disinfected from bacterial pathogens, while in the control with 6-fold disinfection of eggs with vapors of formaldehyde of bacterial pathogens infections were isolated throughout the incubation.

The output of young birds in the experimental batch was 3.6-3.9% higher than in the control, and the safety of young animals up to 20 days of age was also higher by 2.8-2.9%. Economic efficiency per 1 million incubated eggs is more than 420 thousand rubles.
