Description

The invention relates to the field of poultry, namely to castration of roosters.

Kaplunizatsiya or castration (orchidectomy) of roosters is a well-known operation since ancient times, contributing to the successful feeding of birds. A decrease in connection with the capulization of the rooster’s temperament is accompanied by a 13.5% decrease in his metabolism, as a result of which the bird quickly adds to the mass and grows fat. The meat of capons is of exceptionally delicate taste.

A known method of capunization of roosters (Operative surgery with topographic anatomy of animals, edited by Professor K.A. Petrakov. M: Colossus - 2003, pp. 282-283). The rooster is strengthened in a lateral position with legs slightly pulled backwards. The operation site is freed from feathers by plucking and irrigated with tincture of iodine. The abdominal wall is cut with a scalpel, except for the peritoneum. The latter is separated with tweezers, or slightly pulled up in the form of a fold, cut with scissors so as not to injure the intestines. Easily detectable gonads are removed with graduated forceps providing good hemostasis and removal of the entire testis. It is also possible, having cut the skin, to separate the muscles in a blunt way, in particular with a finger, which is then removed (pinched, scraped) and the testis. An experienced worker removes both sex glands through a unilateral abdominal wall incision. However, the abdominal cavity is often opened on both sides, which greatly facilitates the operation. The operation is completed by suturing the skin.

Also known is a method of capunization of cocks (Surgery with topographic anatomy edited by professors E.I. Veremey and B.S. Semenov. St. Petersburg, Quadro-2012, pp. 393-394). Authors taken for analog.

The disadvantages include:

- postoperative bleeding leading to death (Surgery with topographic anatomy edited by professors E.I. Veremey and B.S. Semenov, St. Petersburg, Quadro-2012, p. 394).

As a prototype, the method of capunization was chosen by ligation of the vas deferens according to Alvik (S. S. Bachkov. Poultry farming, No. 1 - 2011, p. 46).

Unfortunately, this method also has drawbacks, so in case of rupture of blood vessels or adrenal tissue during surgery, there may be profuse internal bleeding, which are the main cause of deaths (S. S. Bachkov. Poultry farming, No. 1 - 2011, p. 46) .

The technical result is to increase the meat productivity of egg males and the safety of their livestock.

The technical result is achieved by the fact that in the method of capunization of cocks, including the preparation of the surgical field, local anesthesia, laparotomy in the last intercostal space on the right and castration loops, according to the invention, the castration loop is applied to the spermatic cord.

The claimed technical solution differs from the prototype in the following:

- Completely eliminated bleeding from the blood vessels of the spermatic cord.

According to the scientific, technical and patent information, a similar feature set has not been identified, which allows us to conclude about the inventive step of the claimed technical solution.

Industrial applicability of the method lies in the fact that it can be used in egg poultry farming to obtain additional meat products in an industrial environment.

An example of a specific implementation of the method of orchids roosters.

The authors set the experience in the conditions of the Department of Anatomy, Veterinary Obstetrics and Surgery, as well as the clinical hospital of the Kuban State Agrarian University. To conduct the experiment, taking into account the principle of analogues, 2 groups of Lohmann-Brown egg males at the age of 2.5-3 months were created. (experimental and control) of 15 goals each. In the experimental group, all animals underwent orchidectomy by the proposed method. After 2 months, a control slaughter was carried out and the weight gain in the experimental birds was 15% higher than in the control. At the same time, the safety of the bird was 100%.
