Burdwan: West Bengal BJP unit chief Dilip Ghosh on Monday claimed that cows in the country produce milk which has gold in it and also added that foreign breeds are not "our gaumata" but "aunties".

"The country's own breed of cows have a special characteristic. There is gold mixed in its milk and that is why the colour of their milk is golden. There is a 'nari' (blood vessel) that helps produce gold with the help of sunlight. So, we have to keep those (local) cows. If we drink 'desi' cow milk, we will become healthy and can prevent diseases," he said at a 'Gopa Ashtami' programme here.
