I agree with everyone else...do get a degree, even if it isnt agriculture related...I am personally pursuing a Bachelor's, Master's, and then Doctorate in Animal Science...but its because that is my dream. One thing I will caution all on though(I say this because of a prior post) be careful calling professors people "with no practical experience" it is true that lots of students with no practical experience earn Master's or even Doctorates...but it is more rare for those with no practical experience to get jobs as professors. Practical experience is a HUGE factor when universities are hiring professors...true you may get a lecturer or 2 along the way that dont have much experience, but they typically have a lot of research experience in a particular area that makes them particularly qualified to teach that class...I am not trying to tell everyone to be ag majors...just saying lots of why our industry is successful is because people went and got masters and doctorate degrees, became professors and did the massive amounts of research that developed the feeds you feed, supplements you use, etc.
On a side note should you decide to go towards an Animal Science type degree, choose a school with a good TEACHING farm...notice I didnt say RESEARCH farm...many schools pride themselveson their research farms, which I agree is vital for our industry, however in my opinion many times farms focused on research dont always make the most practical learning environments for students, especially undergraduate students...I feel lucky to go to a university with a farm that is great for the learning environment, but again I work there so I may be biased!
