What are some agriculture related jobs specificly related to livestock?

Next year i plan on going to college but i dont know what for. I want to go for agriculture but before i start i want to have a basis on what specific jobs i want. I work on a crop farm but i dont want the inconsistency of being a farmer soley because of the inconsistent pay. I also raise horses and cattle my dream job would be realating to the world of horses but i have to be realistic and know that foremost i need a job with decent pay. If any of you have jobs or specificly good colleges in the upper midwest that you have attended for agriculture please tell me.
