UPSC Animal Husbandry & Veterinary Science Syllabus

For a UPSC CSE aspirant, the optional subject is also an important subject. In the UPSC mains exam, optional marks have two papers, Paper 1 and Paper 2. Each paper is of 250 marks which makes a total of 500 marks. The UPSC optional subject list contains 48 subjects in total, one of which is Agriculture.

  • Paper-I is mainly related to animal nutrition, reproduction, physiology, livestock management & production, genetics & animal breeding.
  • Paper-II has topics related to anatomy, hygiene, animal diseases, pharmacology, veterinary public health, milk products & technology related to this, meat hygiene & technology.
  • Aspirants with a background in the dairy/meat business, medicine, and those who are veterinary doctors themselves which increase the overall score of the UPSC aspirant increasing their chances of selection.
