Australia: Preventing costly cattle disease to boost fertility rates

The impacts of a venereal disease that causes cattle infertility and costs the industry hundreds of millions of dollars could be mitigated by an experimental vaccine created at the University of Queensland. Professor Ala Tabor from the Queensland Alliance for Agriculture and Food Innovation said vaccines for the bovine trichomoniasis protozoa are available overseas, but not in Australia. "When you import a vaccine, it has to be quarantined and the animals treated with it aren't allowed into the food chain, so it is more efficient and practical to manufacture the vaccine in Australia," Professor Tabor said. "If we can get local strains of the disease and develop them into a vaccine, it's effective, safer and easier—there's no quarantine and the animals can enter the food chain." The work was prompted by the results from a survey for the disease led by Professor Michael McGowan from UQ's School of Veterinary ...
