You haven't mentioned your Category. Nevertheless, for a seat in B.V.Sc through NEET, you will need 500 and more irrespective of your Category. This is because, only 15% of the seats are filled through All India Counselling and the rest 85% of the seats are filled through State Entrance examinations. As the no.of seats available through All India Counselling are less, the cut offs are bound to be higher. So unfortunately, 377 marks is tad less for a seat in B.V.Sc.
