Dr Kumudika de Silva, Dr Karren Plain and Dr Auriol Purdie from the Sydney School of Veterinary Science have been awarded a Meat and Livestock Australia  grant worth $1,084,942 for the research of alternatives to antimicrobials to keep livestock animals healthy.

“It’s wonderful to have our expertise acknowledged by industry in this way. Industry grants are very competitive, so we are very excited to have been awarded a grant of this magnitude,” said senior research fellow and project lead, de Silva.

Bovine respiratory disease
Funded in consultation with the Australian Lot Feeders’ Association, the project seeks to develop a novel vaccine to prevent against bovine respiratory disease – the most common cause of illness and death in Australian feedlot cattle.

“This grant will support research in both the development of a new vaccine and its potential application to a major disease that affects cattle and leads to reduced welfare and performance,” said Senior Research Fellow, Dr Karren Plain.

Cattle vaccine
Most vaccinations for livestock animals are currently given by injection, posing several challenges for feedlots, such as the need for refrigeration and the labour-intensive task of injecting each animal.

“We are hoping to develop a vaccine with properties that make it cheaper and easier to make, store and give to animals than most current vaccines,” said de Silva. “First, we need to understand how these animals will respond to a new vaccination method, but there is real potential for it to be used for many diseases that are important to the livestock industry.”

Working with industry on this project allows a two-way conversation in terms of the science and its application, said Dr Plain.

“We want to be able to make a difference to the health of animals in livestock production systems and also to assist producers in their efforts. It is a win-win.”
