Abstract

FIELD: veterinary.

SUBSTANCE: method involves preparation of surgical area around prepution orifice, infiltration anesthesia, and installation of polyamide ring of 0.6-0.8 cm diametre in the preputial orifice.

Description

The invention relates to the field of veterinary medicine, in particular to the surgical preparation of a male probe.

In the practice of veterinary surgery and veterinary obstetrics, a method for preparing a test boar by vasectomy is known, which consists in excising a section of sperm piping from a mature boar (Shipilov BC et al. Workshop on obstetrics, gynecology and artificial insemination of farm animals. - M .: Agropromizdat, 1988. - S. 42-43). As a result, after the operation, the male retains the ability to have sexual intercourse, but fertilization does not occur, since the ejaculate contains only the secret of the accessory sex glands. There is also a method of preparing a cryptorch boar, when one testis is removed from the boar and the other is introduced through the inguinal canal into the abdominal cavity. So that the testis does not move back into the scrotum, the inguinal ring is tightened with 1-2 stitches of the ligature. In this way, an artificial cryptorch (nutracea) is obtained, in the testis of which the spermatogenesis process is violated (there are no full-fledged spermatozoa), therefore, after mating with such a boar, the sow is not fertilized (Sein OB, Babanin NA A way to prepare a boar probes. No. 439-11 / 2 408-66, issued by the General Directorate of Veterinary of the State Agro-Industry of the USSR on April 22, 1988).

The disadvantage of both the first and second methods is that when detecting sexual hunting in a sow, probing boars perform sexual intercourse and, if a female has genital organs, infection of other sows may occur.

The closest technical solution, selected as a prototype, is a method of preparing a test boar by taking the penis to the side. The method consists in the fact that after fixing the boar, the surgical field is prepared, the hair is cut and shaved on the front of the abdomen around the prepuce posteriorly at a distance of 10-12 cm from its opening and in front to the umbilical tubercle. The shaved surface is washed thoroughly with warm water and a soap brush. Then rub the skin with 70% ethyl alcohol and lubricate with tincture of iodine. Local anesthesia is carried out with a 2% solution of novocaine and the skin and subcutaneous tissue are cut, the initial part of the prepuce bag with the prepuce hole is dissected. The resulting wound is powdered with penicillin powder and sutured with a knotted suture. At an angle of 70-80 ° (to the right of the abdominal line, a new location of the initial part of the prepuce bag is indicated. After local anesthesia, a new linear incision is made of the skin and subcutaneous tissue, equal to the length of the prepared prepuce section. The wound is powdered with penicillin powder and then prepared prepuce is placed in it. The edges of the wound and skin of the prepared prepuce are connected with knotted sutures, lubricated with tincture of iodine and closed with a colloid dressing. On the 12-13th day after surgery, the sutures are removed (Shipilov BC et al. Workshop on aka wool, gynecology and artificial insemination of farm animals. - M.: Agropromizdat, 1988. - P. 42-43).

The disadvantage of this method is the complexity of its implementation and the complications that often arise after surgery. At the same time, in samplers prepared in this way, during the cage, the penis is contaminated and the mucous membrane is irritated (injured) about the female's hairline. The disadvantage of the prototype method is that the removal of the penis to the side (even at 80 °) is not an obstacle to mating the probe boar with the sow, as some probes "adapt" and perform sexual intercourse in the "lateral" position.

The aim of the invention is to simplify the method of preparation of the boar probe, reducing its morbidity, as well as preventing the spread of sexually transmitted diseases.

A method for preparing a probe boar is proposed, which consists in the fact that after preparing the surgical field around the prepuce hole and performing anesthesia, a polyamide ring with an inner diameter of 0.6-0.8 cm is inserted into the prepuce hole. The edges of the prepuce hole are wrapped inside the ring and sheathed around ring rim ligature purse string suture. As a result of the operation, the diameter of the prepuce hole is narrowed, which prevents the penis from going beyond the prepuce hole and prevents intercourse.

The operation is easy to perform, less traumatic, and does not cause complications.

The drawing shows the layout of the ring after fixation in the preputial opening of the boar probe: 1 - prepuce bag; 2 - the head of the penis; 3 - penis; 4 - a ring fixed in a preputial opening.

The method of preparation of the boar probe is as follows. A boar of 5-6 months of age with well-defined sexual reflexes is selected. The boar is fixed in the dorsal position and the surgical field is prepared by cutting and shaving the hair around the prepuce hole with a diameter of 5-7 cm and thoroughly washing the shaved area with warm water with soap and a brush. Then, around the opening of the preputial sac 1, infiltration anesthesia with 1% novocaine solution is performed. After the onset of local anesthesia, a polyamide 4 ring with an inner diameter of 0.6-0.8 cm is inserted into the prepuce hole. Then the edges of the prepuce hole are wrapped inside the ring and sheathed with a purse string ligature around the ring rim. The suture is treated with ichthyol ointment, the sutures are removed on 10-12 days.

Thus, the diameter of the preputial opening is artificially narrowed and only the initial part of the head 2 of the penis 3 can go beyond it, which prevents sexual intercourse.

Boars prepared in this way were effectively used to detect sexual hunting and stimulate sexual function in sows. The method is safe for both boars and sows.
