I am so confused! Just been reading the guidance again, and it says that pigs must be identified before leaving holding of birth with either tag, tattoo, slapmark or temporary mark (so long as under 12 months and just moving between farms), and bearing in mind the discussion we are having it would seem that the temporary mark would be the best for weaners, but it doesn't say they shouldn't be tagged.
Why do there have to be so many different sets of rules, you would think they could have the same ones for different species of livestock, it would be much less confusing. Now hoping Miss Piggy manages to lose her tag in the next few days so I can replace and cross reference in out register.
Thank you to all the knowledgeable people for your help!
Sorry Berkshire Boy, typed all that before you replied, I will put one of our tags in too, thank you.
