QR codes on milk cartons to offer window into livestock health and welfare

 "So far, certification schemes for animal welfare have based decisions on single visits to a farm, maybe once or twice a year, so information is pretty limited," said Dr. Pol Llonch, Technical Project Manager for ClearFarm based at Universitat Autònoma de Barcelona (UAB).

"ClearFarm will be the first platform to provide non-stop, real-time information on animal welfare. Consumers and producers will be able to view information from every single animal on the farm, every single day of the year."


Wearable sensors will continually collect information, including data on activity, eating patterns, and health, enabling the farmer to monitor their animals when they cannot be with them. Farmers can spot health and welfare issues early and take action as appropriate.



As well as a steady flow of information, ClearFarm will integrate the many different recognized 'domains' of animal welfare—health, nutrition, comfort, emotional state and natural behavior. It will combine all of this to give what Llonch describes as "an unprecedented, comprehensive picture of animal welfare."

Llonch is one of eight researchers working on the ClearFarm project at UAB, returning to the institution where he completed his first degree in veterinary science. The welfare and behavior of farm animals is a lifelong passion for him.


It's not just monitoring the traditional aspects of animal welfare that Llonch is concerned with. As the ClearFarm project develops, he is keen to use the latest insights to improve all aspects of animal well-being on the farm.
