Animal Husbandry and Veterinary Science Optional

How to prepare Animal husbandry and veterinary science optional subject for UPSC?

Animal husbandry refers to taking care of farm animals by humans. Veterinary is the treatment of the diseases of birds and animals by diagnosing them through medicines. It covers the study of animal’s physiology and preventing diseases in them. It is one of the optional subjects for the UPSC main exam. it is one of the specialised subject and should be pursued only by those who hold a degree in this field. For the candidates who don’t hold any prior knowledge about this subject then it becomes tough for them to clear the exam and score well in the main exam.

It is not so popular optional subject but is the best optional subject for those who hold a degree in this stream.

Animal Husbandry and Veterinary Science pros and cons

Before choosing an optional subject it is better to know about its pros and cons. Like other optional subjects, this optional subject has its own advantages and disadvantages. It is one of the game changer subject since it hold total of 500marks and can change the rank of the candidate drastically in the main exam.

 

First let’s looks at pros of Animal husbandry and veterinary science optional:

  • Understanding: unlike any other subject, if a candidate has studied this subject for almost five years. So the understanding with the subject would be more and basics would be much clear. Thus choosing it as an optional subject will be a lot advantageous for the candidates. If a candidate choose public administration or geography than he/she has to study from scratch. This will be time consuming and a lot of extra efforts will be required.
  • Syllabus: The syllabus of the animal husbandry and veterinary science is precise and clear. There is a clear distinction about each and every topic which can be easily understood by every aspirant.
  • Good score: Animal husbandry and veterinary science optional is one of the most scoring subjects. A candidate can fetch good marks by drawing flowcharts and diagrams in the answers.
  • Not so broad subject: this subject has all static syllabuses. This makes it easy to understand since a candidate can solely rely on the syllabus and need not to rush to different study material.
  • Same questions:  maximum questions asked in the exam are easy to understand and totally straightforward. Also if a candidate goes through previous year question papers thoroughly then he/she can easily predict about the kind of questions which can be asked in the exam.
  • Less competition: the aspirants in Animal husbandry and veterinary science optional subject are less than any other optional subjects. So a candidate faces less competition as compared to other optional subjects.
  • Helps in GS paper: though this optional subject doesn’t help directly for general studies paper. Still some of the topics like extension, milk and milk product technology and live stock production and management etc helps to prepare for GS paper also.

Secondly let’s have a look at the cons of the Animal Husbandry and Veterinary Science optional:

  • There is limited number of coaching institute available which offers coaching in this optional subject.
  • In addition to this, there is very less study material available for this subject. Therefore, very less amount of study material available doesn’t provide sufficient content to prepare from.
  • Also it is quite difficult to find test series for the main exam.

Strategy to prepare for Animal Husbandry and Veterinary Science optional:

  • Candidates should have enough knowledge about the syllabus. They should be well versed what all topics are the part of syllabus. This is one of the most important step in order to ace through the exam. Also when a candidate gets well versed with the syllabus he/she is in a better position to understand as what can be asked in the exam.

This also helps to differentiate between the topics as the one at which you are good and the ones at which you are not so good. This helps to prepare well for the main exam.

 

  • Candidates should have basic understanding about all the concepts of the animal husbandry and veterinary science. Also each topic should be studied in depth in order to acquire clear understanding. This will also help to solve questions easily and to give proper answers of the questions.

In addition to this use flowcharts and diagrams while answering the questions. It helps to fetch good marks in the main exam.

  • Also prepare notes. These notes help in revision of the entire syllabus during the time of the exam. They boost a candidate’s score in the main exam, since he/she need not to rush behind multiple reference books. Instead of this, they can simply refer to their study notes which were made during the time of preparation.
  • While answering the questions in the exam, a candidate should be updated with all the latest data of the government reports regarding animal husbandry and veterinary science. These data can be used while writing answers and it will help to get good marks in main exam.
  • One of the most crucial aspects of UPSC preparation is to solve past year papers of the optional subject. Most of the questions asked in animal husbandry and veterinary science are from past year paper. These questions are also straightforward. So it very essential to solve past year papers. This will help to score better marks.
  • Hence animal husbandry and veterinary science is one of the most scoring subjects. Students from animal husbandry background can get high marks in it by doing proper study and with basic understanding of the concepts. This is the subject which can be a rank changer since it has very high weight age and contains total of 500marks. By scoring well in this optional subject, a candidate has high chances of clearing the exam with a good rank.
