I study Animal Behaviour and Welfare (BSc). It's actually a degree that's becoming more widespread (University of Bristol have recently started one) because behavioural knowledge is becoming more highly valued in lots of areas of animal husbandry, and being able to perform natural behaviours is now considered a really important part of welfare/wellbeing (which is now being considered seperately to health).
It varies a bit from university to university, so if she is interested, she should look at the content of the courses. Some do cover aspects of physiology and health as part of the welfare side of things, so if this interests her then it might be a good degree. It is a science degree, so there will be some statistical elements, and the dissertation is a research project, not a lit review.
It prepares you for a wide range of animal related jobs, including nutrition (where a lot of the money is!), agriculture, working in a zoo, working for a welfare charity, conservation, working with animals used for experimentation (obviously not for everyone, but some people want to improve the welfare for these animals from the inside).
I think it's a good degree because it's not too narrow (obviously a degree like zoology would have this advantage too). Some degrees, such as conservation, probably don't teach you as much about animal husbandry, and the one at my university is really aimed at people specifically wanting to do in-situ conservation and fieldwork, where there aren't really that many jobs available.
If she any more specific info, then feel free to PM me :)
