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

Tri-Solfen® working for smallholder farming families

May 26, 2020

Working with smallholder farming families, their livestock and FMD viruses in the Mekong & beyond

Original article by Peter Windsor, Isabel MacPhillamy and Francesca Earp for Mekong Livestock Research

In our efforts to understanding how to improve livelihoods in rural SE Asia & regional food security, we are assisting the transition of some subsistence smallholder farmers from poverty to a more viable and sustainable livelihood through investing in improved livestock productivity. This work is focused on what motivates farmers to change their husbandry practices, including better feeding, preventative health & welfare, and improved household financial resilience. The collaborative work has been almost continuous since 2007 in the Mekong, supported by ACIAR-funded projects now completed in Cambodia & nearing completion in Laos, plus a DFAT Business Partnership Platform project that is current in Laos under a recently revised MOU between the partners. Fortunately we have been able to value-add these funding sources by successfully seeking numerous additional sources of support, including the Crawford Fund for field officer extension training, the New Colombo Plan for student participation, John Alwright, John Dillon and Australian Government Fellowship Awards for assisting Mekong scholars, plus collaborations with international agencies (eg OIE, ADB) and universities.

Our work has been examining, through various socioeconomic survey techniques and measures of cattle and buffalo husbandry, health and production, the best interventions for collaborating smallholder farmers to adopt, whilst assisting us to address gender issues on smallholder farms.

The introduction of forage systems and more recently, molasses feed blocks, decreases the work load of ‘cut & carry’ feeding due to ease of supplying readily available nutrition of improved quantity & quality, creating more time for other work/activities and more easily managed livestock. Lao farmers are impressed by the ease of mustering cattle back to villages for overnight housing as the animals seek access to nutrient supplementation blocks containing molasses.  As of mid-November the BPP has moved into a commercial pilot stage that is testing the marketability of blocks to farmers, particularly those that participated in previous efficacy trials and appreciate the production benefits achieved by enhanced nutrition. These blocks are now readily available from the SK Vet Clinic in Luang Prabang, along with project handbooks on livestock husbandry, reproduction and biosecurity.

Farmers have also been impressed with how calf mortality is controlled by simply deworming neonates for the roundworm Toxocara vitulorm and that regular vaccination protects against mortality and morbidity from Haemorrhagic septicaemia and Foot-and-Mouth Disease (FMD). More recently, they have been impressed that treatment of FMD lesions with a simple spray of the wound therapy Tri-Solfen® by Medical Ethics PTY provides relief from suffering, hastening healing and saving on the costs of not treating animals with expensive and unnecessary antibiotics.

Tri-Solfen® treating cattle in Nigeria with FMD lesions

A very important component of our work is to let the scientific community know of the impact of the research and sharing the findings as they may be of benefit to other development programs throughout the world. Our MLR team member and PhD candidate Franny Earp, who has been living in Laos much of this year, recently won a presenters award at the ISESSAH (International Society of the Economics and Social Sciences of Animal Health) South East Asia Conference, in Bogor, Indonesia, October 17-18. This followed her presentation on aspects of socioeconomic modelling of preventative health options data from our projects in Laos, as part of her PhD.

Even more recently, MLR team members Isabel MacPhillamy and Peter Windsor presented papers at the GFRA (Global FMD Research Alliance) 2019 scientific meeting, in Bangkok, Thailand, October 29-31, discussing all things FMD. Isabel addressed the current challenges in implementing effective biosecurity on smallholder farms in the Mekong. Peter introduced the recent findings from Laos on the use of Tri-Solfen® by Medical Ethics PTY as a novel treatment for FMD, suggesting the likelihood that this approach should be part of more effective strategies to reduce antimicrobial use in livestock and limit the serious risk to the human population from AMR (antimicrobial resistance). The Australian company that produces the Tri-Solfen® product (Medical Ethics PTY) agreed to be sponsors of the conference and the Medical Ethics PTY desk was very well attended. During the meeting, images were received of cattle with FMD in Nigeria also having been treated. A number of  conference attendees from other countries took home samples of the product for trials, including scientists from India, Bangladesh, Kenya and Cameroon. Already, cattle and sheep with FMD lesions in Cameroon have now received pain relief treatment for their FMD lesions.

Our extensive work in the Mekong has shown the importance of a systems approach that improves rural livelihoods through increased productivity, focused initially on enhancing nutrition and reducing mortality risk. As learning has continued in our programs, many farmers have continued to improve their livestock husbandry skills and have recognised that healthier more valuable livestock offer pathways for reducing food insecurity and improving rural community resilience. This applied research model from the Mekong, as is well documented on the MLR website under the Resources then Publications tabs (, provides ample evidence that where demand for beef remains strong, enhancing productivity leads to improved animal health and welfare outcomes, with better lives for farmers and their animals through reduced rural poverty. The work of the MLR group is now ready for scale-out!
