SU1790398A3 - Pig artificial insemination device - Google Patents

Description

The invention relates to agriculture, in particular to artificial insemination of farm animals, in particular to artificial insemination of pigs.

Known devices for artificial insemination of pigs.

Universal probe UZ K-5 for insemination of sows, consisting of a metal probe catheter with a soft rubber head, a plexiglass cap, into which two bottles with a capacity of 100-150 ml are placed - one for diluting semen, the other for glucose-salt filler, connecting sleeve , rubber tubes, clamps, handle, Richardson balls.

A rubber tube runs from the Richardson balls in the handle, the bifurcated ends of which are inserted through the cork into the vials. The metal catheter is attached with a sleeve. The device contains spare plastic catheters. When air is forced into the vials through the tubes, it displaces the liquid through the tubes that are lowered to the end of the vials, through which the liquid enters the catheter. On the back of the cap there are clips for each bottle. They allow you to regulate the introduction of diluted semen and solution during insemination of pigs. The bottom of the hood opens downwards. The bottle is replaced through the open bottom. Before insemination, two bottles are placed in the device - one with

1790398 AZ with diluted sperm, the other with glucose-saline solution.

Device T.M. Kozenko consists of a glass jar or a graduated glass or polyethylene bottle with a stopper, into which two rubber tubes are inserted. A catheter is attached to one of them, and a rubber bottle is attached to the other, at the bottom of which a small hole is made. Sperm is injected into the uterus of a pig by gravity or by pumping it into a bottle with air semen. An air filter is connected to a rubber tube through which air is pumped. Before insemination, the air filter with a rubber balloon is separated and the cotton wool is sterilized and reattached to the device.

However, the listed devices have the following disadvantages: they are difficult to manufacture and laborious to use, they do not provide a high percentage of insemination.

The closest in technical essence to the claimed device is a device for artificial insemination of rags POS-5. It consists of a catheter and a 150 ml vial with a screw cap. The catheter 60 cm long has a thickening c at one end. with an outer diameter of up to 14 mm, and on the other there is a connecting sleeve for screwing onto the neck of the bottle, the bottle has a scale with a graduation of 25 ml. However, this device has the following disadvantages: low labor productivity, high up to 40 blanks and significant losses of high-quality sperm due to bougie loss.

The aim of the invention is to improve the ease of use of the device for artificial insemination of pigs.

For this purpose, a dosing container made in the form of a syringe, a piston rod with a flange, a spring to ensure optimal overpressure of the working fluid, a removable elastic balloon (bougie), an adjustable valve to release the excess air pressure into there is an air blower in the rear of the syringe. In this case, the piston rod, in its downward movement, interacts with the flange at the end of the introduction of the working fluid (semen) with the drive element of the adjustable valve to relieve excess air pressure in the bootie. Bougie, air blower and valve are connected by pneumatic lines. In addition, the device includes a separate attachment for semen collection and a retainer for fixing the piston rod in a position corresponding to the required volume of working fluid (semen).

Figure 1 shows a device for artificial insemination of pigs: figure 2 is an adjustable valve for relieving excess air pressure in the booze: figure 3 is a separate nozzle for collecting semen.

The device consists of a syringe body 1 with two screw caps 2,

3. Inside the housing 1 is a piston rod 4 with the ability to move along the longitudinal axis of the housing 1; it is spring-loaded by a spring 5, which is necessary to create an optimal semen injection pressure. A clamp 6 is rigidly fixed to the cover 2, which is necessary to fix the piston rod 4 in positions corresponding to the required volume of injected semen. The axis of the retainer 6 is perpendicular to the longitudinal axis of the piston rod 4. On the cover 2 by means of a threaded connection, an adjustable valve is attached to relieve excess air pressure in the buge 7, so that at the end of the injection of semen the flange of the piston rod 4 interacts with the actuating element of the valve 7. The inserted part ( catheter) 8 is screwed to the cap 3 (when collecting sperm, a removable nozzle is attached to the cap 3 - see Fig. 3). A removable elastic bougie 9 is coaxially placed on the catheter 8. With the help of sealed pneumatic lines 10, the air blower 11 is connected simultaneously with the adjustable valve 7 and bougie 9.

The device works as follows.

To collect semen in the required volume, the piston rod 4, located inside the housing 2, is retracted up until the lock 6 is triggered. In this case, the nozzle for semen collection (see Fig. 3) is connected to the cap 3. Then the catheter is connected to the cap 3. which is fixed bougie 9. Air blower 11, adjustable valve 7 and bougie 9 are connected by pneumatic lines. 10. A catheter 8 is inserted, with an air blower .11, the air pressure is injected in the buge 9 until it is fixed in the vagina. The device is fixed in close proximity to the machine at a height of about 1.3-1.7 m. After stopping the fixation of the piston rod 4, it moves downward under the action of the spring 5, which provides optimal excess pressure for sperm injection. At the end of the movement of the piston rod 4, it interacts with its flange with the drive element of the adjustable valve 7, which releases air from the bougie 9 into the atmosphere. This completes the process of artificial insemination. Catheter 8 can be removed from the vagina.
