Hello Prateek.

With 300 marks, even with reservation, you will not be able to get any government veterinary college as the previous year cut off for OBC category was 540.

However, you might have a chance in private and deemed univerisities. Here is a list-

1. Mahatma Jyotiba Phule College of Veterinary Sciences

2. Khalsa College of Veterinary Sciences

3. Arawali Veterinary College

4. Guru Angad Dev Veterinary and animal sciences university

5. Apollo Veterinary College

The cut off for these colleges is usually above 400, so your chances are difficult.
