Key points of boar castration

1. Castration of young boar. After cleaning the scrotum with 2% Lysol, press the testicles with the middle finger of the left hand, and fix the base of the scrotum with the thumb and index finger. With a knife in his right hand, the 2cm next to the scrotal suture was operated to squeeze out the testicles. After the left hand loosened and pinched the joint of the testes and the sheath ligament, the right hand tore off the white tendons of the fascia ligament and pulled the testis outward. After the left hand returned the total sheath and the ligament to the scrotum, the spermatic cord was fixed. At this time, the right hand loosens the testicles and scratches back and forth on the spermatic cord until the spermatic cord is broken, and then squeeze out the white liquid in the foreskin sac. When removing the other side of the testis, the septum of the scrotum can be cut open at the original wound to expose the other side of the testis and removed according to the method mentioned above.

2. Castration of boar. The operation method of big boar is basically the same as that of little boar, but the way of Baoding is different. In Baoding, the boar needs to lie on the left side of the boar and send someone to press the buttocks of the boar while pulling the right hind leg of the boar forward.

3. Castration of cryptorchidism. Cryptorchidism boar is commonly known as Zouzi pig in folk, which means that the testis of boar is not in the scrotum. Cryptorchidism is generally located behind the kidney of boar, sometimes in the groin. The time for castration of this kind of boar should be from 2 to 6 months. Baoding of cryptorchidism boar generally adopts inverted suspension or semi-supine. The surgical method is roughly the same as the above method, but the choice of surgical department is more complicated, which is generally divided into two cases: one is the posterior cryptorchidism of the kidney. Open at 2 cm at the intersection of the plumb line at the ventral midline of the tubercle. The second is cryptorchidism in the groin. Surgery is usually performed in the iliac region, pubic region, inguinal region, or lumbar region behind the kidney.

4. Scrotal hernia operation. After routine detoxification, the small intestine in the scrotum was moved back to the abdominal cavity, and then the scrotal wall was cut open. When cutting the scrotal wall, do not cut the total sheath. After peeling off the total sheath to the outer ring of the inguinal canal, hold the total sheath and testis to twist the spermatic cord for several weeks, use disinfection thread to cross a needle for ligation, and tear off the spermatic cord and total sheath in the lateral direction of the ligation. The operation is completed.
