Since Tri-Solfen® was commercially launched, over 80 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

EFP partner focus…Medical Ethics

June 29, 2018

As part of Winterbotham Darby’s European Farm Partnership, they caught up with Charles ‘Chick’ Olsson, co-founder of Medical Ethics, to find out more about what Medical Ethics do and why they want to be a part of the EFP.


“Our vision is to develop and deliver highly effective, safe, affordable and practical pain relief products to prevent pain and minimise suffering associated with wounds in humans, livestock and companion animals.”

Chick Olsson:
We’re an Australian Research and Development company, which was set up in 2005. Primarily we started life to deliver pain management and wound care technology to animals but are now looking to see how we can expand that to humans too.

We have a product called Tri-Solfen, which is a combination of wound care and pain relief which was developed by our Technical Director, Meredith Sheil. Meredith worked as a paediatric cardiologist, but was also a sheep farmer too. She had observed lambs, following tail-docking, in pain and wanted to see if human medicine could be adapted to animal medication. The commonality here is that neither animals nor children can express if and how much pain they are experiencing.

So she developed Tri-Solfen, a product which can be applied topically to the site of a wound (such a docked tail) which contains:

These are administrated via a spray and stay gel which sticks to the surface of the wound.

Since our inception Tri-Solfen has been used on over 80 million farm animals in the sheep and cattle sector in Australia and New Zealand.

We became involved in the UK owing to interest shown in us by our partner, Dechra, and other UK companies such as Winterbotham Darby. Recently, 33% of our company was purchased by Dechra, which allows us to expand internationally into every livestock sector.

Our projects are looking at registering Tri-Solfen in UK and EU for all animal species, as well as receiving significant interest from the human health market in Wales. Trisolfen has great potential to be used not only in the majority of necessary farm surgeries, but will also be developed further for human wounds in many areas such as hospital triage and defence forces.

We’re interested in working with Winterbotham Darby because they have shown a real interest in supporting best animal welfare practices with a group of production partners and farms. Specifically with their focus on pigs we could look to reduce pain following piglet castration. Better welfare, such as pain-free surgery for farmed animals resonates with consumers as well as being more profitable for farmers. So it’s a win/win for our animals, farmers and consumers.

We’re excited to share this exciting new research and how it can be developed into welfare programs that we’re creating with Winterbotham Darby. We’re soon to start some trials in Europe, using Tri-Solfen, with a view to obtaining EU approval.

Just like Winterbotham Darby, we’re committed to taking better care of farmed animals, right through the whole supply chain.
