Description

The invention relates to veterinary medicine and selection in the industry of reindeer husbandry and is intended to increase the manufacturability of selection and increase the volume of seed received from highly productive male producers to create a seed bank, evaluate and select males for reproduction by the quality of seed production, to reduce the uterine toxicity.

A known method of producing sperm, including electro-ejaculation and sperm collection (A.S. No. 385582, IPC A61D 7/02).

The used electric ejaculator is cumbersome and does not possess originality in the manufacturability of modern production requirements, and also has a low efficiency of seed output from animals.

There is a method of taking seed from animals, mainly from fur animals, including anesthesia of animals, their fixation in the stall, fastening in a rectum impulse with slip rings, irritation of erotic zones innervating ejaculation, and collecting ejaculate (AS No. 816468, IPC A61D 7 / 02 - prototype).

However, with this method, the ejaculation from animals is irregular and ineffective.

The invention is aimed at solving the problem of increasing the efficiency of ejaculation from animals and the creation of a simple, original and convenient device.

This is achieved by the fact that the electric ejaculator is arranged in one complex technological design, which includes: an adapter with a 6-step supply of alternating electric voltage from 3 to 12 volts; 4-5 copper rings on the probe; voltage indicator lamp and micro switch.

The invention is illustrated in the drawing, which shows schematically an electric ejaculator for selecting seed from male reindeer producers in the field.

The electro-ejaculator contains a probe 1, a housing 2 and a handle 3. The probe 1 is made of fluoroplastic and has openings for supplying wires inside. On the surface of the probe 1, ring electrodes 4 are installed, which are made of copper and connected to wires to supply electric current to them. Socket 5 is installed on housing 2 for connecting an alternating voltage of 220 V and an adapter 6 with an alternating voltage switch in the following range 3-4.5-6-7.5-9-12 V. On housing 2 there is also an indicator light 7. On the handle 3, microswitch 8 is installed.

The device operates as follows.

Electro-ejaculation is the effect of a pulsating electric current on nerve endings located near the male genital organs, normally associated with an erection and ejaculation reflex. This is achieved by placing 4-5 rings-electrodes, 0.7-1.0 cm wide, located through 2.5 cm on the surface of the probe, with a diameter of 20-25 mm, which is inserted into the rectum of the male, cleansed of feces to a depth of 20- 25 cm. Normally, the optimal operating voltage for obtaining sperm products from a deer is set from 3 to 9 volts at a frequency of 50 hertz and a current strength of up to 0.2 amperes. A positive result is achieved if the probe of the electric ejaculator is structurally correct, has good contact and is inserted into the rectum to a depth of 20-25 cm.

In the event that it is not inserted deep enough and the electrodes are not located near the nerves, the amperage and voltage exceed the permissible norms, then painful and unpleasant contractions of the muscles of the animal occur.

As a rule, when using this device of an improved design, stimulation is applied in the form of 5-6 consecutive switching of alternating voltage: 3-4.5-6-7.5-9 volts, lasting 4-5 seconds, with 10-second breaks. This is enough for the male to fully isolate the seed. The power source of the device is portable mini-power plants of the Yamaha or Honda type with a power of 0.5-1.0 kW, which can also be used to illuminate the laboratory room when determining the quality of the seed and in everyday life.

The proposed ejaculator allows technologically correct and convenient to select an increased dose of seed from a reindeer in the field for subsequent research and use.

The device has been successfully tested in 2003-2006. when selecting seed from 43 males. The average volume of sperm obtained was 25-30% higher than when using an electric ejaculator designed by M.E. Mkrtchyan. It was revealed that the proportion of producers with low reproductive capacities varies from 10 to 30% over the years, which undoubtedly affects the barrenness of the uterine population and the productivity of reindeer husbandry in general.

When introduced into production, the proposed device will allow more technologically complete the following activities:

- timely identify producers with low seed quality and eliminate them from reproduction;

- exchange between herds and farms only prepotent male producers;

- create a seed bank from highly productive and endangered deer populations with the aim of preserving and spreading genetic diversity;

- to carry out the crossing of various ecological groups of deer with minimal labor and funds to identify and use the effect of heterosis in improving the productive qualities of animals;

- use a less laborious method when crossing deer;

- importation into the herds not of the producers themselves, but of their seed in order to reduce financial and labor costs.
