Animal Science Practical 5 - Study on castration of Animal

13 important questions on Animal Science Practical 5 - Study on castration of Animal

What are the objectives of casting?

  1. To prevent animals from undesirable mating and breeding
  2. To make the animals docile and easy to handle
  3. For faster body weight gain
  4. To prevent the spread of sexual diseases
  5. To produce a more desirable type of meat

What are the methods of castration?

  1. Open method
  2. Close method
  3. Rubber ring method or bloodless method

What is open method?

By making an operation in the scrotum where the vas defererens are disconnected from the scrotum or the testicles are removed from the scrotum. Thus making spermatozoa will not be able to flow out of penis

What is the close method?

Castration with the help of Burdizzo's castrator. This method is also known as "bloodless castration". The castrator crushes each spermatic cord separately an inch or two above the testicles.

What are the precautions of using the close method/Burdizzo's castrator?

  1. The spermatic cord does not slip away at the time of the operation
  2. Castrator should not press any folds of skin
  3. The burdizzo should not place too low to crush the testicles

What is rubber ring method or bloodless method?

Use of a strong and tight rubber ring around the spermatic cord at the very early age of the calf or lamb. This creates constant pressure on the spermatic cord and disconnects with the testicles. When the testicled have been absorbed, the ring drops down.

How does chemical carponization work?

Inserting a dried pellet of stilbesterol or hexoestral in a skin pocket made in the back of the neck as near the head as possible. The hormone arrests the development of the male sexual characteristics, both primary and secondary, and results in a virtually sexless individual.

What are the precautions of castration?

  1. Should be done during cold season. Strictly avoiding rainy season for fear of fly minace
  2. Castrated animal should be rested for a few days in clean and comfortable pens
  3. Operation wounds must be watched and dressed if necessary once or twice a day

What are the tools required for castration?

  1. Burdizzo's castrator
  2. Elastrator
  3. Antiseptic cotton
  4. Knife
  5. Scissors
  6. Antiseptic solution (dettol)

At what age is castration by the close method performed on cattle?

1 year or above

At what age is castration by the close method by burdizzo's catrator performed on goats?

6 months or above

What is performed within 7 days after birth in sheep and goats?

Close method of castration using rubber ring

What are the components of the structure of the spermatic cord?

  • Testicular artery
  • Testicular vein
  • Ductus deferens or Vas deferens
  • Spermatic plexus
  • External and Internal cremaster muscles
  • Testicular lymphatics
  • Visceral layer of tunica vaginalis
  • Testicular nerve and lymph
