How to stop an out break?
PRC experiences
• Stop tail docking means:
–
–
–
–
–
–
Increased number of tail bitten pigs – even in well managed herds
Increased use of antibiotics
Increased need for hospital pens
Increased mortality rate
Increased need for occupational materials (and increased costs)
The number of condemned pigs will probably be increased
How to get started?
• Experiences from abroad and Antonius
production points out that the risk of tail
biting is reduced if:
–
–
–
–
There is solid floor with straw in the pen
The area pr. pig is increased
The pigs are healthy
Exttra enrichment with nowelty value is
used
– Stress around feeding is reduced
• Sufficient number of eating spots
• Start with a few pens with pigs with long
tails
– Learn how to take care of pigs with long
tails!
– Have a sufficient number of hospital pens
– React on tail biting immediately!
