Zoetis Australia is proud to announce that the new innovative sheep vaccine, GlanEry® 7 in 1 B12, will soon be available in stores near you. This product is a new formulation that combines the market leading proven protection of Glanvac® 6 B12 and Eryvac® into one convenient vaccine.
GlanEry 7 in 1 B12 will be the new gold standard of sheep vaccines as it will protect sheep and lambs against 7 endemic sheep diseases in Australia; Erysipelas arthritis, Cheesy Gland (CLA) and the 5 main clostridial diseases (pulpy kidney, tetanus, malignant oedema, black disease and black leg), all in a convenient 1mL dose. According to the MLA, these diseases collectively cost the Australia Sheep Industry approximately $90M annually.
Dr Kelly Graham, Associate Director of the Zoetis Livestock Veterinary Team is really excited about the addition of Erysipelas protection into the Zoetis Glanvac 6 in 1 range. Kelly indicated that, ‘Erysipelas arthritis, caused by the bacteria Erysipelas rhusiopathiae, is the most common cause of lame lambs on farm and results in significant losses both on farm and at the abattoir. Losses on farm are due to culling, poor growth rates and reduced trading options if animals are unfit to load, and abattoir losses are associated with trim, reduced carcase weights and potential carcase condemnations.’
There are 3 common bacteria associated with arthritis; Erysipelas, Chlamydia and pus-forming bacteria, all of which are commonly found on the sheep’s skin, and in the soil and the environment. Although it is difficult to isolate the causative bacteria when investigating arthritis, recent survey work in southern Australia by Joan Lloyd (2016) found that 57.6% of culture positive samples included Erysipelas. In a Western Australia study, Paton et al(2003), showed that 100% of culture positive cases included Erysipelas. In a southern NSW survey, Ferguson and Munro (2014) showed that 86.3% of culture positive samples included Erysipelas. This research confirms that Erysipelothrix rhusiopathiae is the most common cause of bacterial joint infections in Australian lambs.
Arthritis causes significant loss of production as a result of poor weight gain and reduced wool production in lame lambs, and failure to thrive in lambs with chronic arthritis. An abattoir study1 showed that lambs with arthritis had a reduction in total carcase weight of (HSCW) 1.2 kg compared to healthy lambs without arthritis. This does not include the losses due to trim which have been estimated at approximately 3kg per carcase. In Western Australia, Paton et al4 (2003) also estimated that 1.4% of lambs born, died before weaning or are culled due to arthritis.
When asked where these bacteria come from, Kelly said ‘Erysipelas is found all over Australia and it can persist for a long time in the environment, including in water. It is carried on to a farm by many ways; from introduced sheep i.e. sheep that are chronically infected, by feral pigs, and a variety of other native animals, in fact over 30 species of wild birds and at least 50 species of wild mammals are known to harbour Erysipelas, as well as cattle, dogs, kangaroos and mice. All these animals and birds provide an extensive reservoir, as a source of environmental contamination. So, given this bacterium can survive in the environment and is carried by a range of animals, contamination on any farm can change from year to year, therefore if a farm doesn’t experience infection one year it does not mean it won’t experience problems in subsequent years.’
The most recently published annual report (2018 – 2019) from the National Sheep Health Monitoring Project7, representing the abattoir findings of approximately 8.7 million sheep inspected across Australia, showed a high percentage of sheep lines had evidence of arthritis. Erysipelas arthritis is a significant issue in Australia.
GlanEry 7 in 1 B12 has been developed in Australia and is manufactured in Melbourne, Victoria. GlanEry 7 in 1 B12 provides the convenience of 2 vaccines in 1 with premium disease protection, so will save time, labour and cost whilst making sheep vaccination simple and easy.
