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

Maintaining growth in calves can be helped with the use of pain relief at marking

August 7, 2018
Article by Jamie Brown, originally published in The Land – 6 August 2018, Australia

Werris Creek near Tamworth is feeling the pinch of drought, with failed winter crop turning alluvial flats dun brown. Along the softer northern slopes, native grasses are doing a bit better but Jim Lomax, aged 92, has never recalled it so bad. For Mike and Anita Lomax on Yandilla this is a season that requires forward thinking if they expect to retain breeders going forward. Key to keeping cows healthy is to get their calves off early and that usually mean sacrificing kilos at sale time.

One way to counter some of the loss in weight that occurs during the stressful experience of marking and castration is by using pain relief. In the two years since he adopted the practice Mike says his calves no longer take a backward turn.

Mike’s youngest daughter, Dr Sabrina Lomax, works with the Dairy Science Group at The University of Sydney and did her PhD on pain relief and helped trial Tri-Solfen (Bayer Animal Health) in lamb mulesing and castration with its inventor, Dr Meredith Sheil. The product has been used in calf castration for the past two years.

Enthusiasm for pain relief

Dr Lomax’s enthusiasm for pain relief has rubbed off on her father who says the outlay in cash terms – about $3 a head – more than pays for itself at sale time with increased kilos on the scales.

Dr Lomax advocates two channels of pain relief beginning with Buccalgesic (Troy Laboratories), an anti-inflammatory which has an active ingredient called meloxicam (the patent for which has recently been released, leading to cheaper alternatives).

This is administered to male calves half an hour or so before castration. It’s role is to reduce swelling and discomfort, more appropriately termed the “inflammation cascade”, for the following 24-48 hours. Dr Lomax recommends giving 2.5-5ml orally into the mucosa of the cheek (5mL per 100kg) not down the throat as the active ingredient is absorbed through the mucus membranes in the mouth.

Administering Tri-Solfen

Once the scrotum is opened Tri-Solfen is administered with a drench gun, at 2ml per testis, along the spermatic cord before testes are cut so that the retracting tissue, with all its exposed nerve endings, are bathed in a pool of anaesthetic and antiseptic. There is also less wastage from product spilling on the ground this way. During her studies Dr Lomax was convinced of the efficacy of anaesthetic at marking and castration.

“During our research we found that lambs in pain had trouble mothering-up… Lambs with pain relief were getting back to mum. They could walk and get along. Their wounds were less sensitive, and Tri-Solfen has a barrier effect to prevent the wound and scab cracking.”

Dr Sabrina Lomax, works with the Dairy Science Group

Making a real difference

In calves the result is similar. Mr Lomax  has adopted the pain relief system for the past two seasons and says calves no longer lay on the ground as they once did.

They are up on their feet more quickly and are able to suckle and move ahead. That makes a difference to putting on kilos.

With dry conditions looming from the start of this year Mr Lomax sold weaners in January, rather than March, and turned them off at an average weight of 263kg (for an average daily gain of 1.17 kilograms), compared to the year before when they weighed 279kg (1.02 kg a day) at full term weaning.

This year he will sell in November and hopes to achieve a minimum of 180kg per calf.
