The world's smallest cow 'Rani' died on Thursday due to 'excessive gas accumulated in its stomach'.
Sajedul Islam, livestock officer of Savar confirmed the death to UNB.
"The cow fell ill two days ago. It was taken to Savar upazila health centre at around 11 am today and the on-duty doctor declared it dead at 12 pm," he said.
The dwarf cow of the Boxer Bhutti breed, grew up on a farm at Charigram of Savar, near the capital Dhaka.
The cow stood just 51cm (20in) high and weighed 28kg (62Ib).
It was waiting to be recognised by the Guinness Book of Records as the world's smallest cow.
The cow turned into a celebrity since its news first broke on the newspapers back in July and hundreds of visitors had been flocking to the farm to catch a sight of it.
The title for the world's smallest cow has been held officially by Manikyam, in neighbouring India, which measures 61.1cm from the hoof to the withers.
