M Rajkumar, owner of five bulls from Avaniyapuram, said despite moving from pillar to post to register the bulls for participation through 12 browsing centres and some e-service centres, nothing worked till 5 pm. As many as 210 bulls from surroundings, including Perungudi, Vellkal, Villapuram, Meenakshi Nagar and Housing Board areas of Avaniyapuram have already been registered through screening by the veterinary staff.
