This document discusses debeaking and dubbing procedures for poultry. It explains that debeaking involves partially removing the beak of chickens to prevent feed wastage, cannibalism, and feather pecking. There are different ages at which debeaking can be done, with 7-9 days being best as the beak is still soft. Methods include using a hot blade, cold blade, or bio-beaking tool. The document provides details on each method and stresses the importance of bird welfare before and after debeaking. It also briefly explains that dubbing removes the comb to prevent injuries and make feeding easier.

4. Partial removal of the beak of poultry, especially layer hens also
called beak-trimming.

5. It prevents from,
 Feed wastage
 Cannibalism
 Feather pecking
 Vent pecking

6. There are different ages for debeaking
( Day-old beak trimming )
oAdvantage
• Beak-trimming at the hatchery before delivery of chicks is
relatively cheap
oDisadvantage
• It cause higher mortality
• Beak regrow

7. ( 7-9days )
o Advantage
• 7-9 days “the best age to trim the beak”
• Beak still soft
• Less feed wastage
• Easy to handle
oDisadvantage
• But beak regrow

8. o( 6-8 weeks )
• In this age pullets have more time to regain lost body weight.
• As compared to those beak trimmed closer to maturity.
• Its result more accurate as compared with beak-trimming at an
early age.

9. o (8-16 weeks)
o Two-third of the upper beak and one-third of the lower beak cut
or removed in 12 weeks
oProblems
• More difficult
• More stress
• Loss of body weight
• Require 2-3 weeks to regain weight

10. Hot blade
Cold blade
Bio-beak trimming

11.  Red hot blade cut the beak
 Temp.is 650-750 C
 During cutting blade not closer than 0.3cm to the nostril
 Cauterization time is 3 sec

12.  Beak cut with knife
 But beak can regrow in this method
 This method not used in large scale in industry

13. • In 1980 bio-beaker develop
• Use high voltage (1500 volt AC)
• It burn a small hole in the upper beak of chicken
• It take 0.25sec to burn a hole
• Beak tip falling off in 5-7 days
• Wound healed by 2-3 weeks

14. o Before Debeaking
• The bird in good health
• Do not vaccine
• Supply vitamin k to the bird
o After Debeaking
• Increase the level of feed and water
• Adjust the feeder and drinker according to beak of bird
• Add some vitamins (A,B,K) to the feed

15. • Dubbing is the procedure of removing of comb and
sometime, wattles of poultry

16. • Removing comb bird taking food into mouth easily
• Prevent from injury

17. • Sterile scissors are used
• Dubbing is done when comb is more develop
