Green Livestock Marking Rings - Heavy Duty Rubber Rings for Calves and Lambs in 100, 500 and 2000 Packs These Green Marking Rings are heavy-duty rubber bands used in livestock management for the bloodless castration of male animals and tail docking in lambs. Applied using an elastrator or ring applicator, the band is placed tightly at the base of the scrotum or tail, restricting blood supply to the area. The process is bloodless, and the tissue naturally detaches within 7 to 10 days. They are suitable for use on calves, lambs, and goats, and are available in packs of 100, 500, and 2000 to suit operations of all sizes. The green colour makes these rings easy to identify and can help with colour-coded management systems on farms handling multiple livestock species. Excellent quality construction ensures consistent performance and reliable application with a standard elastrator tool. Having an adequate supply on hand before marking time means the job can be done efficiently in a single session. A standard and widely used tool in Australian livestock management.
