Ananova:

A Vietnamese farmer is playing classical music to his pigs to boost productivity.

Nguyen Chi Cong plays the music of Beethoven, Mozart and Schubert to his 3,000 pigs while they are eating.

The 44-year-old said he started playing recordings of classical symphonies and sonatas over loudspeakers for the benefit of his workers.

But he also found the music had a soothing effect on the pigs, reports Sky News.

"I saw that my pigs started eating more and that they were gaining weight faster than usual," he said.

He now plays the tunes of the great European composers daily from 7-11am and 2-4pm.

"I think I am the first farmer in Vietnam to apply this technique."

Mr Cong, who has run the farm in southern Dong Nai province near Ho Chi Minh City for the past 22 years, said: "Local farmers come here to learn from my experience.

"I think that music is good not just for pigs but also for other domestic animals."
