Well here at the college I'm studying at,(Texas A&M) Animal science is a great option, but look into wildlife and fisheries major. I'm currently within it to become a zoo owner, but a lot of my colleagues are taking it to be ranch managers, however a lot of the courses are more geared towards conservation. Animal science is your best bet though. It does not mean you have to be a vet, its just that option has a high percentage of vets. There are multiple degree plans within each major that can tailor fit to your needs. Here's a link to the Animal Science Production Industry Degree Plan offered here. Look for something along the lines of "<insert college="" here=""> <insert major="" here=""> Degree plans" and it should pull up something.
