I have been looking for private scholarships also. Most are national. So, your residency will not matter. Private scholarships I have found are very specific in their focus.
I have seen vet school scholarships for equine focused students. I was not really intrested in them. They just popped up when I was looking for something else. I think they were under one of the breed associations or something like that.
I have found scholarships also for cattle, which is what I am intrested in. It appears that they are very competitive though. After finding them, one of my friends confessed that she was also applying for it and just didnt tell me because the less that apply - the better her chances are.
It took me over two weeks of careful looking to find some of these. They are there. You just have to find them.
Good Luck!
