formed by cutting down a strip of skin on the brisket
dewlaps
the removal or permanent alteration of the testicles of male
castration
advantage of castration
prevent unnecessary breeding
easy handing
meat quality
disadvantage of castration
less heavy
less mascular
tend to decrease rate of live weight
castration period in calves, lambs, and pigs
calves- 1 to 3 (average 2 months)
lambs- 7 to 14 days
pigs- 1-3 weeks
usually grown for 17-20 weeks and marketed at 3.6-4.5 kg
caponization
done usually at 2-4 weeks of age
caponization
removal of horns in cattle, goat, sheep
dehorning
advantages of dehorning

more uniform
prevent injuries
scoops the horn and horn producing skin
A barnes-type dehorner
used to remove the horn bud plus the horn producing skun
dehorning spoon or tube
destroy the horn producing skin at the base

management of cold stress
- supplying supplement heat by providing high energy content
- reduce heat loss
- use of insulators
