Numnuts has been designed for use on lambs held in the type of marking cradle commonly used in Australia and New Zealand. Numnuts can be used without a lamb marking cradle. When lambs more than 7 days of age are marked a cradle improves the ease with which lambs are held for marking. When lamb marking is carried out at 2-8 weeks of age an animal handling system like a lamb marking cradle is recommended.
