Roundworm found in one-third of tested swine herds in Victoria, Australia
Agriculture Victoria, based in Victoria, Australia, has discovered roundworm (Ascaris suum) in approximately one-third of swine herds tested as part of a newly launched animal health programme, The Mirage reported.
Led by Agriculture Victoria's Principal Veterinary Officer, Dianne Phillips, and her team, the testing initiative covered 45 herds across the state and aims to raise awareness about the risks to herd health.
Dr Phillips said that the large roundworm inhabits the small intestine of swine and, if left untreated, can reduce growth rates by up to 10%, particularly in piglets aged 6-12 weeks.
These roundworm parasites have the potential to block the small intestines and bile ducts of heavily infested pigs, leading to serious health issues.
Roundworm eggs have the capacity to remain viable on pastures and concrete floors for up to a decade, posing an ongoing risk to swine herds.
Dr Phillips said that the swine herds need to be tested, adding that spaces are available, and it's a great opportunity for swine owners to seek information and ask any questions they may have.
As part of the biosecurity programme, which is funded by Victoria's Swine Compensation Fund, Agriculture Victoria aims to test 200 small, medium, and large-scale herds across the state.
The programme provides free roundworm and whipworm testing, and results are reported back along with information about treatment and management options.
Dr Phillips also shared that there have been no whipworm detections in the swine tested to date.
Whipworms (Trichuris suis), located in the large intestine, can cause severe health issues, including bloody diarrhoea, significant weight loss (up to 20% body weight), and a 10% mortality rate in affected swine.
In addition to offering free worm testing, Agriculture Victoria staff have been assisting swine owners in identifying and reducing animal health risks by developing on-farm biosecurity plans.
