RU2314063C1 - Method for preparing experimental bulls - Google Patents

Abstract

FIELD: veterinary science.

SUBSTANCE: it is necessary to dissect scrotal skin, muscular-elastic membrane, fascia and general sheath membrane and spermaduct followed by applying stitches of interrupted suture onto the wound. Moreover, one should dissect spermaduct in area of testicular adnexum caput without taking it out of the scrotum; hemorrhage should be stopped due to applying a ligature out of polycon onto spermaduct being above the incision made. Experimental bulls prepared due to the suggested technique manifested sexual activity several days after operation and kept the ability for normal natural coitus for prolonged period of time.

EFFECT: higher efficiency.

Description

The invention is intended for agricultural enterprises involved in animal husbandry.

There is a method of training bulls-probes (Shipilov B.C. Physiological basis for the prevention of infertility in cows. M., "Kolos", 1977, p.

In the known method, after fixing the bull and preparing the operative field, an incision is made on the front surface of the scrotum of the skin, the muscular-elastic membrane, fascia and the general vaginal membrane, after which the index finger is inserted into the wound and the spermatic conduit is removed by hook from the wound, and released its from the mesentery and excised. Next, the operation is repeated as in the resection of the first sperm conduit. The wound is sprinkled with white streptocide and 5-6 stitches of a knotted suture are applied to the skin. The edges of the wound are lubricated with tincture of iodine, covered with a thin layer of absorbent cotton and filled with collodion.

The disadvantage of this method of training bull probes is:

- as a result of the removal of the spermatic cord along with the sperm conduit and its release from the mesentery before excision, the infection gets into the wound and an inflammatory process develops, which can lead to sterilization of the bull;

- during excision of the sperm line, bleeding is not stopped, which also leads to the development and complication of the inflammatory process, and sometimes to the unsuitability of the bull to identify females in the hunt.

The objective of the proposed method of training bulls-probes is to simplify the operation and increase the reliability of the method of training bulls-probes.

This task is achieved by the fact that in the known method for preparing test bulls, including an incision in the skin of the scrotum, muscular-elastic membrane, fascia and the general vaginal membrane, excision of the sperm duct, according to the invention, the sperm duct is excised in the region of the head of the epididymis, and a ligature from the polycon is applied to the sperm duct incision to stop the blood.

The method of training bull probes is as follows.

Bulls aged 1-1.5 years with developed genitals are selected. Before surgery, the bulls are examined for brucellosis, tuberculosis, leukemia, chlamydia, vibriosis. In preparation for surgery, analgesia is used: atropine 0.1% - 2-3 ml subcutaneously, after 15-20 minutes, a solution of xylazine 2% is administered intravenously in a dose of 1.5-2 ml, novocaine 2% in the epidural space at a dose of 10-20 ml

In preparation for surgery, the hair of the operative field of the anterior surface of the neck of the scrotum is trimmed with a clipper. After that, the surgical field is washed with an antiseptic solution, wiped dry and treated with 5% iodine solution 2 times. An incision is made in the skin of the anterior surface of the neck of the scrotum, muscular-elastic membrane, fascia and the common vaginal membrane. The testis is pulled to the wound opening and in the area of the appendage head, the sperm conduit is perpendicular to the testis excised without removing it from the scrotum.

After excision of the sperm conduit, bleeding is stopped by applying a ligature from the polycon to the sperm conduit above its excision.

This violates the conductivity of sperm from the testis to the urogenital canal.

The common vaginal sheath is sutured with catgut No. 1, the wound is sprinkled with streptocide on the wound of the scrotum, intermittent interrupted sutures are made of polyester thread. The wound is treated with tincture of iodine and aerosol.

A similar operation is carried out to excise the sperm duct of another testis, through another section of the scrotum, parallel to the first.

To determine the effectiveness of the proposed method for training sample bulls, 8 bulls were operated on and used to identify sexual hunting and stimulate sexual function in cows and heifers.

When determining the effectiveness of the proposed method for training sample bulls in the scientific and economic experience, no postoperative consequences were found. Sample bulls prepared by the proposed method showed sexual activity a few days after the operation and for a long time retained the ability to normal natural sexual intercourse.

Claims (1)

A method for preparing test bulls, including an incision in the skin of the scrotum, muscular-elastic membrane, fascia and the general vaginal membrane, and excision of the sperm duct, followed by suturing of the stitches of the nodal suture, characterized in that the seven duct is excised in the area of the head of the epididymis without extraction from the scrotum, and bleeding is stopped by applying a ligature from the polycon on the seven-wire above the incision.
