Cattle fair organiser Maskhoor Khan said the decision was taken to prevent cows and their progenies from getting slaughtered.
Khan alleged that slaughterhouses in neighbouring Sambhal and Bijnor districts purchased cows in the fair.
The cows were then transported to the slaughterhouses in the said neighbouring districts, he said.
Over a lakh animals, including buffaloes, goats, calves are traded annually in the fair, Khan said.
