Hi!
I've a degree from veterinary faculty in Non-EU country.I like to do research in any subject about animal health but I don't know where can I start. do I need to do MSc before PhD or I can apply for PhD now in UK?? Thanks a lot...

I have a vet degree and I went straight on to do a PhD, so you don't need to do a masters. I think you need to decide what area you want to go into to as 'animal health' is a bit vague. If you approach a university and say that you want to do a PhD in animal health then I doubt they will take you seriously. There must be some particular areas that interest you the most.
