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

Brazil about to move forward with pig welfare law

August 14, 2018
The Brazilian government has launched an initiative that should lead to the obligation of group housing for gestating sows as well as several other improvements in pig welfare.
To that end, the Brazilian Ministry of Agriculture, Livestock and Supply initiated a so-called ‘public consultation’, this July. Producers, consumers, as well as NGOs and the Brazilian Agricultural Research Corporation (Embrapa) have all been invited to share their views on pig welfare, which is possible until October. The views of the World Organization for Animal Health (OIE) will also be taken into account in this respect.

Minimum standard welfare requirements

The outcomes of the public consultation will eventually all be taken into account in new legislation which will stipulate minimum standard welfare requirements, on issues like e.g. group housing, castration or tail docking.

It is the next step in an ongoing trend to introduce more animal welfare in Brazil. Since about 2000, the country has adopted humane slaughter regulations. The country’s 4 largest pig producing companies, representing over 60% of the Brazilian herd, have already publicly committed to phase out sow crates by 2026. Various more progressive farms have also made the switch.

Matching other exporters’ pig welfare standards

Improving the welfare issue appears to be unstoppable trend as Brazil would like to match other exporters’ standards, like e.g. Europe or the United States. Nevertheless, the main importers of Brazilian pork don’t make any high welfare specifications, think of e.g. China, Russia, Hong Kong and other countries in Latin America.

Liziè Buss, chief of the ministry’s Welfare Division, summed up the essence of the upcoming changes, “Our proposal covers definitions of production systems, structures, management care, indicators for assessing welfare and farm productivity; mitigation of painful procedures such as ear tagging, castration, teeth clipping; euthanasia procedures; inclusion of enrichment for animals to reduce fights and stress.”

Ms Buss said, “For each situation, there is a deadline for the producers’ suitability. We are not copying European legislation, but making our own rules facing the reality in Brazil.”

For instance, with regard to group housing as well as piglet weaning, the idea is to arrange a deadline in 20 years from now for all pig producers in Brazil. With regard to mitigation of surgical castration without pain control, the term would be 2 years.
