Steinfort funding to commercialize the technique. During steining a set of clamping jaws designed by Steinfort is used to pinch up rolls of skin near the tail and anus of a lamb. Once sufficient skin is in the clamps liquid nitrogen is pumped through the jaws and onto the pinched skin. This rapidly freezes the lamb's skin. The goal is to achieve the level of cellular injury that prevents future hair growth but not so much that a 3rd degree cold burn is created. Pinching the skin is thought to mitigate the degree of the cold burn by removing it somewhat from the muscles and connective tissue beneath. The treated skin goes through the same stages of healing seen in the long method of freeze branding, terminating with permanent hairlessness. Studies show this method is at least as good at preventing flystrike as mulesing and carries few long-term consequences for the lamb's later growth and wool production. Steinfort and others invested in the process have claimed it is less painful and distressing to the animals on which it is practiced. They argue that affected nerve endings are immediately numbed and that sensation does not return during healing, when a scab forms and is eventually sloughed in 6 to 8 weeks. A 2018 study found behavioral markers indicating pain and distress in lamb who had been steined without analgesic treatment compared to those who had been given analgesics. In 2020 a University of Melbourne researcher named Ellen Jongman was commissioned to study the issue by the company Steinfort formed to commercialize his technique, SteinfortAgVet. The name of Steinfort's company subsequently changed to AgVetInnovations. On December 22, 2020 Jongman released preliminary results from her study on the relative pain of mulesing and steining. Jongman found that mulesing and steining were equally painful on the day of the procedure but that steined lambs appeared to be in less pain than mulesed lambs on subsequent days. Her study tracked and interpreted a series of lamb behaviors like the speed at which it returned to its mother after undergoing either mulesing or steining. She called for further research using physiological data such heart rate and blood sampling in addition to behavioral observations. Jongman's final report was released on January 25, 2021. In March of 2021 AWN cut ties with Steinfort and divested from this application of freeze branding. As of July 22, 2021 the position
