The invention relates to livestock industry 5, in particular, to problems of artificial insemination of agricultural animals,

The aim of the invention is to prevent the occurrence of autoagglutination. I Figure 1 shows the usurastvo,: horizontal section; in FIG. 2, the same, vertical section; on figl - block diagram of the device; 4 is the simplest electrical circuit of the device; on Ifig-functional diagram of the device.

The device consists of a housing 1 in which a rotor 2 and a stator 3 with vertical grooves are fixed, in which winding 4 of the inductor is placed, a vessel 5, filled with biological object 6, is placed between the rotor and stator, winding 4 of the inductor and the neutral wire is connected to the voltage conversion unit 8 and the software block 9 (Figures 1-3). The stator 3 is made similarly to the I stator of an asynchronous three-phase electric motor with the number of poles equal to 2 p, where. The rotor 2 is made massive of any magnetic material. The vessel 5 for a biological object is made of a non-magnetic material (glass, etc.). The voltage conversion unit 8 can be made in the form of a regulator capable of varying the voltage from 0 to the nominal voltage (for example, a three-phase autotransformer can be used).

The program block 8 includes time relay 10 and voltage adjusters 11, time 12 and frequency 13. Inductor: 14 is connected via diodes 15 to frequency control 16, performed on thyristors. A voltage regulator is supplied to the frequency controller from the voltage regulator unit 17 (Fig. 5). As a voltage regulator, an electronic voltage regulator NIL can be used.

The simplest scheme of the device implementation is presented in Fig. 4, where the following symbols are adopted: inductor 14, diodes 15, rectifier 7, button Stop 18, button Start 19, coil 20 of time relay 10, coil of magnetic starter, contacts 22-24 magnetic starter 21, three phase. autotransformer 25 (applied as voltage regulator 17), contact 26 time relay 10.

The device works as follows.

The vessel 5 with a biological object 6 is placed between the rotor 2 and the stator 3. Software block 9 sets the program (time delay, frequency induction value), winding 4 of the inductor through rectifier 7 and the voltage conversion unit is connected to a three-phase network. A magnetic field is created in the vessel volume by the induced windings 4. This magnetic flux moves in a circle with a speed, rotates. The speed of rotation of the magnetic field is determined by the formula

o-f

where p 3.14;

f-frequency;

p is the number of poles.

When in the frequency range of 0.2–200 Hz, one can obtain the rotational speed of CO 1, 256–1256 s. Since in real conditions the direction of the sinusoid current is changed, the positive part of the sinusoid is used in the device to unidirectional magnetic field. This is achieved by using diodes 15 of rectifier 7 in the device circuit, which pass only positive part of the sinusoid to windings 4 of inductor 14.

The rotor 2 is designed to amplify the rotating magnetic field.

There is a processing of a biological object. After a certain period of time I has specified a time relay 10 has elapsed, program block 9 turns off frequency controllers 16 and voltage 17. The device is disconnected from the network.

The simplest principle of the device operates as follows.

The three-phase autotransformer 25 sets a certain magnetic induction voltage. A field (which ... is proportional to the current strength and voltage value of the voltage converter unit 8). The time relay (coil 20, pin 26) sets the time delay.

He presses the Start button 19. In this case, the coil 21 of the magnetic starter will have a current, a magnetic starter

triggers and closes its contacts 22 - 24. Contacts 24 connect the autotransformer 25, and therefore the Idctor 14; pin 22 blocks the start button 19, and pin 23 turns on the time relay 10. At the same time, the countdown begins after a predetermined time interval, the time relay 10 opens its contact 26 in the coil circuit of the magnetic actuator 21. The magnetic starter opens its contacts 22-24, and the device is disconnected from the network A, V.C. To switch on the device, press the Start button 19 and the cycle of work will be repeated.

A semen batch is made with a unidirectional pulsating magnetic field rotating in space for 10 minutes.

For processing, a field with the following magnetic characteristic is used: induction 0.35 T, rotation speed 104.5 s

Processed in this way, sperm is examined under a microscope. These microscopic findings prove that

a pulsed rotating field treatment completely eliminates the phenomenon of auto-agglutination.

After sperm treatment, the sows are inseminated to prove that auto-agglutination is eliminated and the fertilizing ability of the sperm increases.

Three experimental groups of bi-biological unidirectional media with 14 heads each were created.

The first group is seeded with semen, treated with a pulsing magnetic field of 0.05 T for 16 minutes.

The second group is seeded with sperm treated with a pulsating magnetic field T for 8 minutes.

For insemination of the third group, semen is used, treated with a field of 1.2 T for 1 minute.

The inseminated sows were kept in groups, the feeding regimen and the diet of the sows were set in accordance with the norms of the VIZH.-,.

The gestation period lasted 114-116 days.

As a control (IV group) use the method of processing sperm.

microelectric power, which increases the efficiency of exposure.

Thus, the device makes it possible to significantly increase the fertility of the sperm by preventing the effect of autoagglutination.
