there is no firm guidance in place yet from what i have seen, they have looked at a change in meat animals and non meat animals separately, if it does not get passed for meat animals it has a very good case for it being changed for animals not intended for the food chain. the research document is 66 pages long and quotes many different options, but what does seem to be consistant is that they support a change is required for non food chain animals, they recognise the welfare implications of tagging but the more people who show their support the more notice they will have to take.
if it does result in one tag still being required for both food chain and non food chain animals it will be very disappointing but at least an improvement on what we have to put them through now, however this may only apply to food chain animals.
