Supercomputers help target bovine TB

Researchers will use supercomputers to predict bovine TB status of dairy cows.

Animal health researchers in the U.K. are planning to use "deep learning" as a key weapon in the fight against bovine tuberculosis (TB) in the country's cattle herd.

The U.K. has been facing a long-running, widespread and highly controversial bovine TB outbreak.

Livestock scientists at Scotland’s Rural College (SRUC) have been awarded £337,000 for a project that will use highly advanced computers to predict the bovine TB status of dairy cows, an announcement said.

By analyzing millions of milk samples with a greater degree of accuracy than ever before, it is hoped that the project will strike a significant blow to a disease estimated to cost the U.K. dairy industry around £175 million a year, SRUC said.

Deep learning — a branch of machine learning — employs algorithms and techniques to make better use of increasingly huge data sets and advances in computer technology.

Previous research by SRUC and collaborators has already led to the development of the U.K.'s first national genetic and genomic evaluation for bovine TB resistance of the Holstein breed as well as the launch of TB Advantage by the country's Agricultural & Horticultural Development Board (AHDB).

By using mid-infrared spectroscopy of milk samples from National Milk Records, SRUC researchers previously confirmed the existence of significant genetic variation among individual animals for resistance to bovine TB infection.

SRUC said the funding follows a U.K. Department for Environment, Food & Rural Affairs review of its 25-year bovine TB eradication strategy, which now specifically includes “improved genetic resistance and improved diagnostic tests.”

The new SRUC project, which is being funded by the Biotechnology & Biological Sciences Research Council, will produce data that can be used for management and diagnostic purposes but also potentially for inclusion in national genetic evaluations for bovine TB host resistance.

“This is potentially a great step forward in the fight against TB. Being able to use routinely collected milk samples to alert a cow that may have been exposed to infection will allow the farmer to take remedial action long before the normal testing regime comes in," SRUC professor Mike Coffey, who is leading the project, said.

“The early removal of infected cows should lower the background level of TB and contribute to enabling more effective outcomes from the existing tools deployed to eradicate the disease,” Coffey added.
