• Council Directive 2008/120/EC
‘before carrying out tail-docking other measures are to be taken to prevent tail-
biting and other vices, taking into account environment and stocking
densities. For that reason, inadequate environmental conditions or
management systems are to be changed’
‘ensure that pigs have permanent access to a sufficient quantity of material to
enable proper investigation and manipulation activities, such as straw, hay,
wood, sawdust, mushroom compost, peat or a mixture of such (‘enrichment
material’), which does not compromise the health of those animals.’
• March 2016: EU commission recommendation (2016/336) on application of the
2008 Directive on tail docking
• Staff working document developed and available to provide guidance

Where to next…
We need to be able to rear undocked pigs in Moorepark…
• Maybe the rack is ↑ important than we realised
Finnish experience:
• Reduce no pigs/pen (0.9 m2 finishers since 2012)
• Our pens = 10.02 m2: 12 pigs = 0.84 m2
• Reduce competition at feeder • Considered ↑ important factor for Finnish farmers
(Valros et al., 2015)
• Breed?
Open to suggestions!

Take home message!
• Control of tail biting outbreaks in undocked pigs is extremely
difficult
• Step-by-step process of determining which methods work
• Farm specific
• Looking like the ban on docking will enforced reasonably
shortly – post 2019?
Must be addressed before it becomes a non-compliance
issue!
