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

Worlds largest beef company mandates use of Tri-Solfen®

March 18, 2020

Article originally by Mark Phelps, Queensland Country Life

AUSTRALIAN Agricultural Company chief executive officer Hugh Killen says good rain over the bulk of the organisation’s properties had helped reset the premium beef business after years of tough drought conditions.

While saying the drought in some areas was still a long way from broken and the catastrophic North Queensland floods in January and February 2019 had taken a big toll, he said the company was now in a much better position to capitalise on global markets through its premium beef brands.

Mr Killen said coronavirus was the new challenge, likening it in some ways to a natural disaster, similar to the floods, droughts, and the bushfires that had devastated parts of Australia.

That disease was still to play out through global economies, but would likely impact on supply chains.

Mr Killen said animal welfare was also central to management of the company’s supply chains.

“Animal welfare sits in three core principles around sustainability more broadly,” Mr Killen said.

“We’ve been operating this business since 1824 and by that nature we’re a sustainable company. We approach everything we do from a sustainable fashion.

“First is the land we own and operate, number two is animal welfare, and number three is our employees and the people on our properties.”

Mr Killen said central to AACo’s animal welfare program was the use of the pain relief product Tri-Solfen®, which had been mandated for use across the cattle herd.

While selectively used across in recent years, the decision to make its use mandatory was partly based on large scale trials which had shown Tri-Solfen® increased productivity and made cattle calmer. In particular weaners retained more body weight and were better at mothering up, he said.

“At a $1.50 a dose it’s not a huge impost,” Mr Killen said. “I believe the production benefits you get in terms of kilos on, mothering up and the general health of the animal makes it a no brainer.

“Whether it become mandatory, I don’t know. Whether it makes good business sense. Absolutely.

“But whether it is one extra kilo or five extra kilos isn’t the point. It’s actually the right thing for the animal.

“If we can do the right thing for our animals, that’s the right thing for our consumers.”

Mr Killen said said different markets had different priorities. Europe for example was interested in hyper-local product, while Thailand was concerned about plastic in the supply chain.

“But I believe animal welfare is always in the middle and central to the questions they have about the integrity of the supply chain.”
