This technological move has much to moo about. A dairy farm in Russia has arranged for virtual reality headsets for its cows to “reduce their anxiety”.

A BBC report said that the VR systems were specially adapted to fit onto the cattle heads, showing a “unique summer field simulation programme”.

The Russian Ministry of Agriculture and Food quoted research to claim a link between a cow’s emotional experience and milk yield.

Initial tests are said to have boosted the “overall emotional mood of the herd”.

A Ministry statement said that the experiments were conducted at the RusMoloko farm in Moscow’s Ramensky district.

“Examples of dairy farms in different countries show that the quantity — and sometimes quality — of milk increases markedly in a calm atmosphere,” it added.

Researchers now plan to examine the effects of the programme on a long-term basis.
