Since Tri-Solfen® was commercially launched, over 150 million lambs have been treated and over 80% of Australian wool growers are now using Tri-Solfen for their sheep. Here’s what some of them have to say…

‘We have used pain relief for two years now and seen real production gains. We are concerned for the welfare of our animals and will continue to use pain relief to ensure they get the best care.’

Clinton Wise– Wililoo Merino Stud, Woodanilling, W.A.

'It easy to see the difference pain relief makes. Before, lambs would walk away hunched up, even taking a couple of hours to walk back to the paddock. Now they run straight back to Mum and start suckling,” says Rod. “My wool is now sold under the Better Choices brand. I see this as a definite advantage. I think it will be an advantage in the long run, to both me and the industry as a whole.'

Rod Miller– Glenpaen Merino Stud, Horsham, Vic

'After being treated with pain relief my lambs were more content and less stressed. As farmers we are sincere in looking after the welfare of our animals and using pain relief demonstrates this.'

Richard Coole– Frankland, W.A.

'We have been using pain relief for the past three years. We’re impressed by reduced bleeding in the mulesing wound immediately after application. Lambs run straight back to find the ewe, which has dramatically reduced our mortality rates. Flock management, post lamb marking is easier due to the effect of pain relief and the scab healing faster.'

Ryan & Malcom O’Dea– Peepingee Merino Stud, Narrogin, W.A.

'Using pain relief eases the stress and allows lambs to mother up and move back to the paddock easier with faster weight gains.'

Kent Lummis– Waverley Downs, Gilgandra, NSW

Proven, affordable and practical pain relief solution for surgical and accidental wounds in all animal species


Innovation in pain relief

Tri-Solfen® is a Veterinarian prescribed, farmer applied pain relief product sprayed directly onto the wound during surgical procedures such as castration, tail docking and disbudding. The product is designed to provide an adhesive barrier over the wound, numbing the area and minimising bleeding whilst providing protection against infection.The use of Tri-Solfen® is recommended by leading livestock industries, international retailers, animal welfare groups (including the RSPCA and CIWF) and highly respected welfare scientist such as Temple Grandin and Professor Peter Windsor. There has been over 150 million animals successfully treated with Tri-Solfen® addressing the urgent needs of producers and their customers to improve animal welfare outcomes. Pain management in livestock production is top of mind for many producers who want to improve animal welfare outcomes, for veterinarians who have the difficult task to help producers to improve welfare standards in a practical and cost effective manner and for consumers and governments that are increasingly demanding the improved humane treatment of animals. This has lead to livestock supply chains globally creating and enforcing new strict animal welfare codes with large retailers requiring producers to implement practices to improve the wellbeing of animals including the alleviation of pain. Currently available pain treatments are either costly or impractical for use, disrupting management practices. Tri-Solfen® is an innovative solution developed with producers and their animals in mind providing a practical solution for improved animal welfare outcome.

“A breakthrough for all livestock farmers around the World – finally a common sense approach to a highly complex issue”

Tri-Solfen® has changed wound care in animals

Meredith Sheil invented Tri-Solfen®. Her career was originally in paediatric cardiac research before she spotted a need for better treatment of animals, and recognising how human medicine could benefit livestock and farming practices. The work she and Medical Ethics have done in the area of animal wound care is now one of the products leading the way for animal welfare.
