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

World 1st: Tri-Solfen® approved for use in calves

December 15, 2016

In a ground breaking new development for farmers and for animal welfare – the Australian Veterinarian Medicine regulator (APVMA) has now extended the approved use of Tri-Solfen® anaesthetic and antiseptic topical application to include the alleviation of pain in calves.

Tri-Solfen® is already approved by the APVMA, and widely used in over 8 million lambs per year to alleviate pain from husbandry procedures such as castration, tail docking and mulesing.

Tri-Solfen® has a unique 3-way action designed to numb the wound, minimise bleeding and protect against infection. Scientific trials have demonstrated pain alleviation up to 24 hours in calves after surgical castration and a significant improvement in wound healing in lambs. To date, Over 70 million animals have been treated with Tri-Solfen®, with the product purchased over the counter in Australia from local veterinarians or from rural retailers.

On-going trials conducted by Sydney University Veterinary School and were used to support the registration, confirmed that Tri-Solfen® is highly effective and safe to alleviate pain post castration and disbudding in calves. In addition recent studies conducted by Sydney University have also confirmed a significant reduction in pain associated with piglet castration and these studies will be used to extend the use in piglets in the near future.

It is a major win for farmers, a win for calves, a win for animal welfare – and a win for the Australian cattle and dairy industry says Allan Giffard, Managing Director of Animal Ethics. Tri-Solfen® is now approved to provide a practical means for farmers to alleviate the pain associated with husbandry procedures in calves, which are relied on for important animal health and management reasons. This in turn may improve mothering-up, minimise set-back, while also addressing consumer concerns over welfare.

‘Farm animals experience pain in the same way as dogs, cats and other companion animals. They deserve the same respect and effort to develop safe, affordable and effective pain relief and wound care that is practical for farmers to use. Tri-Solfen® provides the first important product to address this need’.

Allan Giffard concluded “This is a very exciting milestone for our company and the new calf registration sets a solid platform for Animal Ethics as we continue our international registration program in key markets such as the USA, EU, Canada, New Zealand and South America.

About Tri-Solfen®

Tri-Solfen® is a local anaesthetic and antiseptic gel spray that adheres well to wounds and acts as a barrier to environmental stimuli, promotes haemostasis and improves wound healing. Tri-Solfen® contains two proven topical local anaesthetics; fast-acting Lignocaine for immediate pain relief and long-acting Bupivacaine for prolonged post-operative pain relief.
