how should candidates apply for veterinary with neet Mark...how many should require for Bvsc in tamilnadu ggovernment colleges

You can take admission in BVSc when there would counselling for the various AYUSH courses .It will start once the admission for MBBS and BDS is over .But merely appearing in NEET won't do .You should have a minimum score of above 400 to get admission in a government veterinary college .

In TamilNadu we haveTANUVAS(TamilNadu Veterinary and animal sciences University) offering B.VSc. &AH., - 5 and half years course including one year compulsory internship. TANUVAS have 4 colleges viz Madras Veterinary College, Chennai and other colleges located at Namakkal, Orathanadu, Tirunelveli.

Best wishes. Thank you.
