You can study animal husbandry and veterinary medicine, animal nutrition, animal genetics and breeding, aquaculture, wildlife protection and nature reserve management in agricultural and forestry colleges. According to your own idea, if you want to start your own farm, I advise you to go to a better farm and learn directly from your experience. But most of these majors are only for learning basic theoretical knowledge, which is far from practical application. It is difficult to find a job. I majored in wildlife protection, so it is difficult to find a job. I suggest you study a more practical major and get a good job.
