Camera system could alert farmers to tail biting
Tail biting occurs unpredictably and can spread rapidly through the litter.
Researchers developing technology into early warning system

A camera-based system to identify signs of tail biting in pigs could help farmers prevent outbreaks, according to new research.

Writing in the journal PLOS ONE, researchers show that pigs hold their tails down and close to their body when tail biting is about to begin. In a series of experiments, researchers placed 3D cameras above feeders to automatically measure when the pigs’ tails were up and curly, or held down. 

The study was conducted using 23 groups of
pigs that were regularly scored for signs of injury to their tail. Researchers monitored the pigs closely and put a stop to the tail biting as soon as they detected an outbreak.

Tail biting is a financially devastating disease of which there is no single cause. Elements of the pig’s genetics, nutrition, environment and management are all thought to contribute to its spread.

When an outbreak of tail biting occurs, it does so unpredictably and can spread rapidly through the litter. Tail docking was once used as a measure to control the disease, however this is no longer seem as an acceptable solution.

“Tail docking of piglets is partly effective at reducing tail biting in later life, but is seen as an undesirable mutilation and its routine use is banned in the EU,” explained lead author Dr Rick D’Eath from Scotland’s Rural College (SRUC).

“This research has achieved everything we hoped for. We can automatically measure tail posture, and we’ve proved it can act as an early warning of tail biting. The challenge for us now is to develop this promising technology into a robust on-farm early warning system that works on any pig farm.”

The concept is now set to be developed into a project called “TailTech” funded by Innovate UK. The project will gather data from more diverse pig farms and develop and test a prototype early warning system.

New app to improve street dog welfare

News Story 1
 A new free app will support vital work in clinics caring for stray dogs around the world, experts say. Created by the University of Edinburgh, the tool allows vets to track the wellbeing of dogs going through catch-neuter-return schemes, which are common in countries with large numbers of strays.

Vets say the welfare of individual dogs can be overlooked during the process of capture, transport or surgery. The app, piloted across Asia and Africa, helps staff to monitor welfare, spot signs of distress and develop strategies to improve care. It was launched at BSAVA Congress on Friday 6 April.

Farm to fork traceability championed in new service

Defra has created a new information service to offer farm to fork traceability when the UK leaves the EU. The Livestock Information Service, which is set to be operational from 2019, will identify and track animal movements via electronic IDs, meaning the industry and government are better placed to respond in the event of a disease outbreak.

Environment secretary Michael Gove said: “This service will be instrumental in improving traceability and providing guarantees to consumers about the origin of their food. NFU President Minette Batters, among others, has helped lead the way on this, showing how it will drive a progressive and vibrant livestock industry once we leave the EU.”
