To put it as it is both courses are at par, taking into consideration the immense job opportunities that both these courses offer to a graduate. Both these courses ultimately provide the resources for farmer life and his well being.

   If you are interested, comfortable with pets, milch animals or wildlife then think no more, opt for veterinary.
 
  If in the contrary you are interested in plants, crops, soil and natural resources you should opt for a career in Agriculture .It has more broad opportunities due to the several disciplines that come under it like - Agronomy, Crop protection, Plant Breeding, Soil science, Microbiology, Statistics and so on.

So choose the course according to your personal and intellectual interests.
