Castration

1. Department Of Medicine, Surgery And Obstetrics HSTU,Dinajpur-5200 A PRESENTATION ON CASTRATION

2. CASTRATION Definition : Surgical removal or destruction of testes. Indication : To make the animal docile. For easy management in the presence of female animal. To prevent animal from unwanted breeding. Correction of scrotal hernia. To promote weight gain in meat animals.

3. Species on which castration is done mostly in our country: Cattle Goat Cat Dog sheep Cattle 1-2 months Sheep,Goat 2 weeks Dog 6-9 months Cat 5-6 monyhs Best age of castration

4. Dog Fasting : (6-8) hours Control :Using squeeze box ANESTHESIA :General Anesthesia is done Premedication : Diazepam (1mg/kg)+ Atropine (0.05mg/kg) Induction :xylazine HCl (1.1mg/kg)+ Ketamine HCl (5.5mg/kg)

5. Position :Dorsal recumbency Incision site : Pre-scrotal region After anesthesia clipping and shaving the incision site and painted with tincture iodine

6. CASTRATION PROCEDURE IN DOG: Incised tunica vaginalis

7. Ligate spermatic cord

8. After removing close by suture

9. Surgical Procedure : The skin just infront of the scrotal sac is incised The testicle and tunica vaginalis is elevated through the hole in the skin The tunica vaginalis is incised and the testicle exposed (this is open method) The testicular blood vessels and spermatic cords are ligated Through same procedure other testicle is removed The subcut fat layers and skin are sutured closed

10. CAT Castration in cat is same as dog, but the differences are For Premedication Acepromazine (@0.1mg/kg) is used. In cat plucking is done due to less hair and thin scrotal skin Incision is made over the scrotum & 1 incision is made for removing each testicle Due to large ductus deference ligation can be done with it,no need of suture material.

11. 2 incision for 2 testicle over scrotum

12. CATTLE Surgical castration : Open method: Animal restrain in lateral recumbency & perform anesthesia(local:2% lidocaine HCl )(6-10) ml (Ring block or inverted V-block at the base of scrotum) Incision is made down to the anterior surface of the scrotum. The testicle & tunica vaginalis is elevated; incise tunica vaginalis & remove the testicle after ligating spermatic cord. Repeat the procedure on other testicle.

13. INSTRUMENT FOR CASTRATION IN CATTLE: Burdizzo castrator Ruber ring Elastrator forceps

14. 2. Burdizzo castration(bloodless method) Restrain animal in lateral recumbency and anesthetized by 2%lidocaine HCl (6-10)ml. It is a clamp like tool use to crush & disrupt the blood vessels supplying the testicle. That causing them atrophy & die .

15. Elastic band castration: A tight rubber band is placed around the neck of the scrotum by elastrator forceps to cut off blood flow to the testicle . Over time testicle shrink & fall off. Useful for calves Elastic band method

16. SHEEP & GOAT Castration of sheep & goat is same as for cattle : Surgical method: Open method: scrotum & tunica vaginalis is incised Burdizzo castration(bloodless): smaller size burdizzo castrator is used Elastic band castration : a tight rubber band is placed around the neck of the scrotum by elastrator forceps. It is useful for lamb; kids. BURDIZZO METHOD IN GOAT

17. Overall Complication of Castration : 1. Infection 2. Anxiety 3. Swelling 4. Bleeding 5. Pain and discomfort 6. Persistent masculine behaviour

18. Post operative Care 1.Antibiotic 2.Anti-inflamatory 3.Antihistaminic 4.Regular dressing wound area. 5.Restrict movement.
