We vaccinate with Gudair, then 6-1 with B12 and Selenium. Follow this with a scabiguard vaccine. Then a numbered PIC tag, a brass stud tag, and finally a de-tailing. We used a gas knife, as this has proved less painful to the lamb than a rubber ring, (we swab the area with a fly repellant). We like to mark lambs as young as possible, and have found the cradle pictured as the best for a mixture of lamb sizes. We still use a rubber ring on the testicles, the suffering seems fairly short lived.
