OJD vaccination gives market advantage
The Riverina Livestock Health and Pest Authority are advising sheep and goat producers to continue or commence vaccination programs for ovine Johne’s disease to reduce losses and maximise market opportunities.
Phil Humphries, Riverina LHPA Animal Health ranger says the authority regularly receives enquiries about the value of using Gudair vaccine for ovine Johne’s disease control.
"OJD appears to be spreading west from the traditional areas so it’s timely that producers look at their options for managing OJD," he said.
"Furthermore, we are seeing increased demand for vaccinated breeders at store sales, which is another reason to vaccinate against the disease.
"Gudair vaccine can help to break the OJD cycle by preventing or delaying its spread. The use of Gudair and good husbandry can help to manage OJD, minimise risk and improve trade.
"Only one vaccination is required which costs approximately $2 per sheep or goat.
"Animals are usually infected for at least two years before developing signs of the disease. Once they start to show signs, they usually deteriorate and die within six months – there is no cure.
"In Australia, death rates of around 10 per cent are common in flocks where OJD is not managed."
Mr Humphries said producers should exercise caution when they are vaccinating their animals.
"It is very important that the animals are restrained adequately during vaccination. It is advisable to inject young lambs or kids at marking time or at least before 16 weeks of age. Vaccinated animals must be identified with an NLIS tag with a ‘V’," said Mr Humphries.
"Wethers that are destined for the meat trade don’t need to be vaccinated. Remember to keep a line of NLIS sheep tags without the ‘V’ stamped on them for use in these wethers.
"Gudair is an important tool in the fight against OJD and sheep and goat breeders are urged to play their part in managing this significant disease."
