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

Pain relief blocks draw funds

October 4, 2018

An Australian researcher is one of three scientists to receive a major grant through Bayer’s new Care-4Cattle program.

Original article by Penelope Arthur for the North Queensland Register

The three recipients were announced during Bayer’s Future Farming Dialogue being held in Germany and the Netherlands last week. Dr Dominique van der Saag was selected for her research into novel ways in which calves can self-administer pain relief after husbandry practices such as de-horning or castration. Together with her team of five scientists, Dr van der Saag uses medicated lick blocks to provide a constant level of pain relief in a way that limits the handling of the cattle, therefore improving
welfare outcomes. “Whilst studying my bachelor in animal and veterinary bioscience at the University of Sydney, my interest in livestock and animal well-being really grew,” she said.

“This could be a strategy to improve cattle well-being.”

Dr van der Saag

“I began to see how improvement of livestock welfare through the use of pain relief was extremely important.” Dr van der Saag said that in many countries, it was not mandatory to use anesthesia or analgesia for painful procedures performed on cattle. “However, there has been a shift in recent years, with producers wanting to take on pain relief practices so long as they are feasible to implement,” she said. “This is the first step towards something that could be much bigger. Currently there are no practical options for long-lasting analgesia in livestock, which is necessary not only for surgical husbandry procedures but many painful conditions.”

“If we can show it has the potential to be effective, this could be a strategy to improve cattle well-being. We would really like to see this grow into something bigger. The Care4Cattle initiative was launched by Bayer in March this year and attracted more than 100 entries across 37 nations. Each of the three winning projects will receive grants worth just under A$50,000.

The initiative aims to recognise forward thinking livestock professionals who have created new ways to advance cattle well-being. The other winning projects include a study by Brazilian Professor Mateus Paranhos da Costa on the effects of different weaning methods on beef calves and an initiative from Reuben Newsome at The Cattle Lameness Academy in the UK to support farmers in dealing with the rising threat of lameness.
