Tesco's false moo-ve over cow advert

But the advert has upset farmers in Shropshire – who say the supermarket has picked the wrong kind of cow.

Tesco has advertised the big drop in price on its milk supply by using images of Hereford cross cows.

But they don't provide a drop of milk to help stores fill their pint bottles.

The breed is instead used exclusively in the beef industry.

The blunder has upset farmers who claim it shows the large supermarkets are out of touch with farmers.

Richard Yates, who has a herd of 100 Friesians near Bridgnorth, said it demonstrated the company's lacklustre attitude to suppliers.

"They are using Hereford cross cows which are 100 per cent beef animals that would never have been milked in their lives," Mr Yates said.

He added: "That shows how out of touch they are and what they think of dairy farmers."

Neither is Mr Yates the first person to spot the mistake, as others took to Twitter to highlight the supermarket's mistake.

"Dear #tesco why do you have pictures of beef cows,while promoting cheap milk?" wrote one user, who posts under the name @freerangechef.

Another called @loweroxleyfarm wrote: "Come on Tesco this is a rural market town and they know you don't milk beef cows."

After being contacted by the Shropshire Star, Tesco admitted its mistake and vowed to replace the signs with others which show a dairy breed.

Tesco spokesman Alasdair Gee said: "As soon as we spotted this mistake we organised for new pictures to be used.

"Customers can expect to see the new adverts in their local store very soon."
