AI does grunt work on China's pig farms

From BBC - February 14, 2018

Artificial intelligence technology has been developed to help piglets survive their first months - and then to decide which sows to kill.

The scheme is being rolled out in China, the world's biggest producer and consumer of pork.

It marks the latest deployment of tech giant Alibaba's ET Brain cloud computing service.

China's pig industry is notoriously inefficient, but one expert said the tech could also prove useful elsewhere.

For now, the trial is limited to the country's Sichuan province.

Alibaba teamed up with local feed provider Sichuan Tequ and the farming group Dekon to develop the solution.

It claims that it should on average lead a sow to rear three additional offspring a year, and reduce the death rate by 3%.

The system is designed to maintain a profile of each animal, including details of their weight, age, food intake and exercise, among other details.

Vision recognition software - which relies on a number tattooed onto each swine's side - is used to keep track of each pig.

The sounds of their squeals are analysed to try to determine if any of the young ones are at risk of being suffocated under their mothers' weight.

The AI tech also listens out for coughs, which along with infrared temperature readings are used to act as an early warning system for disease outbreaks.

This should help farmers know when to provide specialised vaccinations.

And when the technology detects a sow's productivity rate has fallen below the norm it suggests she is slaughtered.
