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

Dehorning Daisy? Better make it painless.

December 9, 2013

A UBC researcher finds that calves experience emotions like depression and anxiety

University British Columbia’s Dairy Research Centre

Calves can experience depression and anxiety, suggests new research from the University of British Columbia, raising ethical concerns over cattle dehorning procedures.

study led by Heather Neave, the first to use a cognitive test to address the emotional response to pain in any species besides humans, found calves showed signs of pessimism after having their horns removed.

“The study shows they’re not just animals who have a sensory response,” said Neave, a recent master’s graduate of UBC’s Animal Welfare Program. “They possess the cognitive ability to pass judgment, interpreting ambiguous events more negatively.”

Dairy producers dehorn cattle using a chemical paste or hot iron to reduce the risk of injury to farmers and other animals. Previous research on dehorning has shown the procedure elicits behavioural and physiological responses in the animal, but little is known about the emotions it conjures.

At the UBC Dairy Research Centre in Agassiz, B.C., Neave spent three weeks training 17 calves to perform a simple task where they had to decide whether or not to approach a video monitor inside their pen, depending on the colour displayed on the screen.

Experiment explores emotional depths of calves

Using milk as a reward, half of the calves were trained to approach the monitor when it was red and avoid it when it was white. The other half learned the opposite. The calves quickly learned the suggested meaning of the two colours, and were then introduced to three shades of pink that could be interpreted positively or negatively.

Neave ran the task with the calves before and after the calves were dehorned with a hot iron at 30 days old. She found that the calves showed no change in their approach to the red or white screens, but approached the ambiguous pink screens less frequently following the procedure, taking the dim view that they would not be rewarded with milk.

According to Neave, this pessimistic response shows the calves are experiencing negative emotions.

“Statistical analysis refuted other plausible explanations for their reduced response to the ambiguous screens,” Neave said. “Human literature indicates emotions influence our interpretations and judgments of ambiguous information, which was a similar response exhibited by the calves.”

Neave wants to see dairy producers provide pain medication to their cattle in the form of a sedative and anesthetic before dehorning and a painkiller post-procedure.

Many farmers do provide pain medication during the procedure, but the pain experienced afterwards is typically not treated. Neave administered a sedative and anesthetic on the calves she trained, but withheld a painkiller in order to conduct the experiment.

Results hit home for dairy farmers

Most dairy producers cite time and cost as reasons for not providing the pain relief, but Neave says her study has them thinking twice.

“The feedback I get in conversation with dairy producers is positive,” she said. “They are surprised to learn that calves are able to complete the task and it really hits home for them when they realize the animals have an emotional response to the procedure.”

Other researchers at the centre are using the same experiment to study the impact of calves being separated from their mothers, and to probe the potential benefits of the animals being housed with a partner.

“Some dairy farmers are now moving away from dehorning altogether, by using genetically hornless animals in their herds,” Neave said. “We have a special responsibility to prevent this pain.”  Refer to Article
