Hii madhan,

There is only 15% seat for veterinary science education on all India basis.e merit to get admission in any government recognized Veterinary College will be made according to the numbers achieved in NEET exams.

Cut off vary every year based On the difficulty level of the paper. It's also depend on the category, the category you belong to like Open, SC, ST, OBC..

Cutoff also vary for government, private and deemed University. 
It depends also on state of domicile and choice of college.

So for safer side try to score 350 +marks for geeting seat in Veterinary college. 

Good luck...
