Though you have not mentioned your category i assume you to be of general category.since for other categories cutoff is much less

For BVSc 

Ow category previous year cutoff was 68.6

And for CW category it was 67.4

80 marks are quite a good score even then, you can get bsc in every branch since according to previous cutoffs ,they never touched 80marks for opening cutoffs

GOOD LUCK
