- 1 week
- 1 month
- 1 day old — Correct Answer
- 3 days old
Explanation:
Correct Answer: 1 day old
Both debeaking (beak trimming) and Marek's disease vaccination (HVT-MD vaccine) are performed at day-old chick stage (1 day of age).
Debeaking
- Debeaking prevents cannibalism and feather pecking.
- Done at day-old using a hot blade that cuts and cauterizes the beak tip simultaneously.
- The upper beak is cut slightly shorter than the lower beak.
Marek's Disease Vaccination
- HVT (Herpesvirus of Turkey) vaccine is the most commonly used live vaccine against Marek's disease.
- Administered subcutaneously or in ovo at day-old.
- Marek's disease is caused by a herpesvirus that causes neural and visceral tumours (lymphoma).
Other Age-Specific Management
- Dubbing (removal of comb, wattles, earlobes): Done at 3-day-old chick stage.
