I obtained my bachelor degree in Animal Science and chose to minor in both Equine Science and Agricultural Business. I am presently employed by a local feed company as their equine representative (ie: answering horse related nutritional and care questions, recommending feed products, marketing and sales, etc.) and I would say that having a degree was a useful resume booster. Granted, practical experience and knowledge is always important.
I enjoyed getting an Equine Science degree because it exposed me to many different sectors of the equine industry: training, breeding, nutrition, etc. I would highly recommend it in some form, but also keep in mind that you may want to broaden your degree to allow for different occupations and opportunities.
